Title: Understanding the Nature of PHL 1811 Analogs

PI Name: William Brandt

A central tenet of X-ray astronomy is that luminous X-ray emission is a universal property of efficiently accreting supermassive black holes. However, we have recently studied a population of type 1 quasars that challenge this idea: PHL 1811 analogs. These objects are all X-ray weak and have exceptional UV emission-line properties. We propose snapshot observations of 10 bright radio-quiet PHL 1811 analogs that will more than double the sample of these objects with sensitive X-ray coverage. The improved sample size will better characterize the X-ray weakness of this population and allow correlation tests with emission-line properties. The improved photon statistics will aid joint spectral analyses investigating hints of hard X-ray spectra and X-ray absorption.

Title: Gas Dynamics of Wide Angle Tail Radio Galaxies: A Chandra Study of the ICM around 3C 130

PI Name: Ralph Kraft

We propose a 60 ks Chandra/ACIS-S observation of the cluster gas around the canonical wide-angle tail radio galaxy 3C 130 to determine if the transition from collimated jets to diffuse lobes/plumes is the result of an interaction between the jet and the ICM structure. In particular, we will search for surface brightness discontinuities in the cluster gas at the position of this jet-> lobe transition. Such interfaces and strong shear flows along them commonly occur in merging clusters. Hydrodynamic simulations show that jets bend and entrain material at these shear flows. If detected, this would conclusively demonstrate that the WAT phenomenon is related to cluster merging and resolve a long-standing question in jet dynamics.

Title: Determination of Dark Matter Fractions and M/L in Elliptical Galaxies

PI Name: David Pooley

Sparsely sampled X-ray observations (every >=5 years) of stellar microlensing in quadruply gravitationally lensed quasars offer two powerful methods of determining the dark matter to stellar matter ratio in the lensing galaxies. The first is by measuring the frequency of caustic crossings over time. The second comes through treating these widely spaced observations as independent snapshots of the stellar content of the lensing galaxies and using them in a single-epoch analysis. The random motions of the microlensing stars in the lensing galaxies ensure that widely spaced observations will effectively sample independent rearrangements of the stellar content.

Title: X-ray Confirmation of Optically Selected Kpc-Scale Binary AGNs

PI Name: Xin Liu

Binary Active Galactic Nuclei (AGNs) with kpc separations offer an important laboratory to study the accretion and evolution of SMBHs in mergers, the effects of merger-induced AGN on galaxy evolution, and the initial conditions of pc-scale binary SMBHs. Despite decades of searching, and strong reasons that they exist, X-ray verified kpc binary AGNs are scarce and mostly serendipitous. We propose ACIS-S imaging of a pilot sample of high-quality binary-AGN candidates optically selected from our systematic survey. The detection of two luminous hard X-ray nuclei in each system will provide robust evidence for binary AGNs. The results will characterize the success rate of optically-identified binary-AGN candidates, and will likely double the number of X-ray verified kpc binary AGNs.

Title: The Hierarchical Assembly of Massive Black Holes: Identifying Kpc-Scale Triple AGNs with Chandra, HST, and EVLA

PI Name: Xin Liu

We propose to image three optically selected kpc-scale triple-AGN candidates with Chandra, HST, and EVLA. The detection of three luminous hard X-ray point sources in each system would confirm their triple AGN nature unambiguously, enabling the first direct evidence for galaxies containing triple massive black holes. The joint HST and EVLA imaging will help characterize the excitation mechanism of the observed emission (AGN, starburst, and/or shocks), and will explore host galaxy morphologies and spatially resolved star formation activity in these unique mergers.

Title: Caught in the Act: X-ray Imaging of the Highest-Redshift Binary AGN in a Lensed Submillimeter Galaxy Merger

PI Name: Asantha Cooray

As the most intensively star-forming galaxies, submillimeter galaxies (SMGs) carry important clues to the mass assembly history of massive elliptical galaxies. With Herschel, we have identified a 1:1 merger of two bright SMGs at z = 2.31, with contemporary starburst and black hole accretion in both partners. The proposed Chandra observation will directly confirm the binary AGN hypothesis making this the most distant system with a binary AGN separated by < 10 kpc in physical separation. We will use broad Halpha dispersion to establish the balckhole masses of the system. This unique dataset will prove invaluable for our understanding of the complex physical processes inside the progenitors of the elliptical galaxies today.

Title: Keeping Tabs on the Unique Jet in M87 During Cycle 14

PI Name: Daniel Harris

We request 2 observations of the M87 jet at 5 ks each. The first should be in 2012Dec (the beginning of the "TeV M87 Season") and the second in 2013 March (halfway through the season). There are two reasons for this modest proposal. The first is that if our M87 ToO is triggered, we can understand the results much better if we have some idea as to the intensity of each component in the jet before the onset of TeV flaring. The other reason is to ascertain if the nucleus, the highly variable knot HST-1, or knot D (known to be variable in the optical) have increased substantially since the last time we obtained Chandra data (2012 Feb). If we were to find a substantial change, a DDT request would be instigated.

Title: A late time look at the candidate relativistic tidal disruption event Swift 2058+0516

PI Name: Andrew Levan

In 2011, we discovered two examples of an apparently new class of high energy transient. Named Swift 1644+57 and Swift 2058+0516, they are exceptionally X-ray bright events, accompanied by emission across the electromagnetic spectrum. A working model for these events has emerged, explaining them as the tidal disruption of a main sequence star by the central supermassive black hole in a distant galaxy, although alternative models remain plausible. Here we seek long term observations of the second event, Swift 2058+0516. Using Chandra we will measure the lightcurve at late times while the source is too faint for the Swift-XRT. In doing so we will determine the late time properties of the object and compare the late time lightcurve to the expectations for tidal disruption events.

Title: TeV Flaring from M87: Triggering Chandra to Detect an X-ray Counterpart

PI Name: Daniel Harris

From VERITAS, HESS, and MAGIC observations, it appears that there are TeV flaring states for M87 which last a few days to a week or more and provide many detections at a level significantly higher than the quiet state . Because we model the TeV emission as IC scattering by the same electrons responsible for X-ray synchrotron emission, we expect that TeV variability will be mirrored in the X-rays. To determine the location of TeV flaring, to further constrain X-ray time scales, and to obtain simultaneous photometry to refine sync/IC calculations, we request a Chandra ToO program to be triggered by TeV flaring. We request a maximum of 70 ks, divided into 5ks observations so as to construct a lightcurve for comparison with those obtained by the Cherenkov observatories.

PI Name: Guido Risaliti

We propose a 200 ks ACIS-S observation of the Compton-thick AGN in NGC 4945, with the aim of performing an unprecedented spatially-resolved spectral analysis of the clumpy circumnuclear structure. With its superior angular resolution, Chandra is the only present X-ray observatory capable of resolving the central reflector in the source. A spatial and spectral study of the continuum and Iron Kalpha emission would pose a cornerstone in the understanding of the environment surrounding the central engine of AGNs.

Title: ENERGY DEPENDENT X-RAY MICROLENSING AND THE STRUCTURE OF QUASARS

PI Name: Christopher Kochanek

The structure of the X-ray emitting regions of quasars remains an open question. Using microlensing in lensed quasars, we can now constrain the sizes, finding that they are compact compared to the UV emission (2500A) with 1/2 light radii of ~10-30 gravitational radii. We propose measuring the relative sizes of the hard and soft X-ray emission, better constraining the overall X-ray sizes and comparing them to the hottest regions of the accretion disk by coarsely monitoring 6 lenses with CXO (6 epochs each) and 5 with HST/UV (2 epochs). In essence, the variability amplitudes of the X-ray/UV compared to our well-sampled optical light curves allows us to measure the sizes. We request ~2/3 (1/3) of the time in Cycle 14 (15) for a total of 864~ks (with slew tax) and 12 HST orbits.

Title: The Energetics and Shielding of FeLoBAL Quasar Outflows

PI Name: Fred Hamann

Quasar accretion disk outflows are ubiquitous and potentially important for feedback affecting host galaxy evolution. The `FeLoBAL' variety of these flows, with very low-ionization broad absorption lines (BALs), is found exclusively in starbursting/young hosts with a remarkable inverse correlation between the BAL strengths and star formation rates that is strongly indicative of feedback. However, it is not known if FeLoBAL outflows are truly capable of feedback because their energetics and basic physical properties are still poorly understood. We propose ACIS-S observations of 3 carefully-selected FeLoBAL quasars to place unprecedented new constraints on the outflow physics using a combined analysis of the X-ray absorption plus ground-based measurements of diagnostic BALs in the rest UV.

Title: Chandra Confirmation of Candidate Inspiraling, Binary, or Recoiling Black Holes in Nearby Galaxies

PI Name: Jeremy Darling

We propose to observe two candidate supermassive massive black holes (SMBHs) offset from their host galaxies to confirm that they are indeed black holes and to detect dual black holes at the host galaxies' centers. Chandra observations will provide the key confirmation of offset black holes and will be the culmination of an intensive many-year multi-wavelength systematic search for off-nuclear inspiraling or recoiling SMBHs in a complete sample of 923 nearby 2MASS galaxies containing radio sources >100 mJy. This survey simultaneously addresses three scientific problems: (1) SMBH/galaxy co-evolution implied by the SMBH/bulge mass correlation, (2) the "merger-tree" theory of SMBH evolution, and (3) the expected contribution of merging SMBH binaries to the gravitational wave background.

Title: 3C 111: An Ideal Galaxy for Reavealing Jet Physics

PI Name: Eric Perlman

One of Chandra's milestone discoveries was that many quasar and radio galaxy jets are X-ray emitters. The X-ray emission process for these objects has become the source of much debate, with both synchrotron and inverse-Compton radiation possible, and with implications that impact not only jet physics but also cluster feedback models. To obtain the best constraints it is critical to study long, nearby jets. We therefore propose deep Chandra+HST observations of 3C 111, which has an extraordinary, 1.5-arcminute long X-ray jet. We will constrain the X-ray and optical morphologies of the knots and hotspots, and obtain X-ray spectra and SEDs for all components. This will constrain the emission mechanism and the evolution of jet parameters as a function of distance from the AGN.

Title: A High-Resolution Study of Long-Term Absorption Variation and the X-ray/UV Connection in NGC 3783

PI Name: William Brandt

We propose a 170 ks HETGS observation of the bright Seyfert 1 galaxy NGC 3783 to explore the new parameter space of high-resolution warm absorber (WA) variation in ionization, structure, and kinematics over 11 yr. NGC 3783 is the ideal candidate for such a long-term variation study, due to its extraordinary baseline of HETGS (from 2000-2001) and UV spectroscopy, its extremely rich absorption spectrum, and its X-ray/UV brightness. In addition to mapping long-term WA evolution in unprecedented detail, we will assess joint X-ray/UV absorption variations over long time scales with a supporting HST COS spectrum; substantial UV variations over the past 11 yr indicate that corresponding X-ray variations should be detected and be physically informative.

Title: The Herschel Legacy of powerful 3C radio galaxies and quasars II: observing Proposal.

PI Name: Joanna Kuraszkiewicz

We propose X-ray observations of 23 sources from a well-defined sample of 77 z < 1 3CR radio sources for which we were allocated Herschel observations (PI Haas). The inclusion of Chandra and Herschel data will complete their radio-X-ray spectral energy distributions allowing us to quantify the orientation-dependence of AGN radiation, investigate the interplay between accretion and star formation and understand the evolution of the black-hole/stellar-bulge relation. The X-ray data enable us to determine the strength of any nuclear activity, estimate the obscuration, study the orientation dependence of the X-ray properties, probe the nuclear geometry with full SED modeling and study evolution via comparison with our higher redshift/luminosity 3CR sources.

Title: Testing the slim disk scenario for active intermediate mass black holes

PI Name: Elena Gallo

Chandra observations of high luminosity intermediate mass black holes from the Greene & Ho (2004) sample show that the optical to X-ray spectral slope is flatter then in more massive systems. This is interpreted as evidence for slim disks operating in IMBHs with bolometric luminosities above 10 per cent of the Eddington limit. In order to test this scenario, we propose new observations of a parent sample of optically selected IMBHs with bolometric luminosities in the range -2

Title: The Remarkable Case of NGC 5252: Turning Chandra into a Time Machine

PI Name: Junfeng Wang

Ionization cones in Seyfert galaxies are among the best evidence for both AGN unification models and AGN-host galaxy interactions. We propose for a 180 ks ACIS-S imaging spectroscopic observation of NGC 5252, an S0 Seyfert 2 galaxy that exhibits spectacular optical ionization cones characterized by a series of prominent ridges. Adding this to the existing Chandra, HST and radio data, we will: (1) Characterize the ionization structure along the cones, thereby reconstructing the activity history of the nucleus on ~10^4 to ~10^6 years timescale; (2) Study the detailed X-ray morphology and spatially resolved spectra of the extended narrow line region, to determine whether at least part of the diffuse emission is due to an outflowing wind driven by the central AGN.

Title: Feedback in 3C 277.3

PI Name: Andrew Young

We propose multi-wavelength Chandra, EVLA and Gemini-N observations of the radio galaxy 3C 277.3 to determine how its radio jet interacts with its environment. The jet in this object is deflected by ~30 degrees when it runs into a cloud of gas, which produces a radio, optical and X-ray emitting "hot spot". The X-ray observations will reveal the morphology and emission mechanism associated with this jet-cloud interaction. The radio maps will show the flux and polarization, and trace the path of the jet. The optical integral field unit spectroscopy will reveal ionization and velocity gradients across the jet-cloud interaction. Obtaining high quality data of these feedback processes is important because they play a key role in regulating the formation and evolution of galaxies.

Title: Are Double-Peaked Optical Emission Lines Reliable Indicators of Dual AGNs?

PI Name: Claire Max

How frequently in the merger process are both SMBHs active as a pair of AGNs? To search for dual AGNs, we got Keck II Adaptive Optics NIRC2 imaging of double-peaked [O III] emission line SDSS AGNs. Out of 112 double-peaked AGNs imaged, 32 objects (29%) show double spatial components that lie within 3 . However, there are many other explanations for double spatial structure, such as interacting jets, a chance superposition, etc. Only Chandra has the spatial resolution necessary to confirm these true dual AGNs with small (< 3 ) pair separations. We propose to use Chandra ACIS-S for a total of 215 ksec to image 12 galaxies with both dual spatial structure and double-peaked [O III] emission lines to test the efficiency of the presence of double-peaked lines as indicators of true dual AGNs.

Title: Probing The Causes of the High/Low Jet Power Dichotomy in AGN Jets with Chandra and HST

PI Name: Preeti Kharb

We propose for deep Chandra-HST observations of 3 hybrid MOJAVE quasars. As these sources have jets with different powers (Fanaroff-Riley type I & II) on either side of the central engine they could be the touchstone for ideas put forth to explain the question of the FR dichotomy and the nature of AGN jets in general. These deep observations will constrain unambiguously the X-ray emission mechanisms in these jets through the construction and modeling of broad-band SEDs at multiple jet positions. The X-ray imaging may reveal asymmetries in the hot gas on either side of the AGN, telling us about jet propagation in low/high power sources. The lack of such features may provide support to the idea of highly magnetized jets, which could be examined further through broad-band SED modeling.

Title: Joint Chandra/XMM/EVLA Monitoring of the Gas Cloud G2 as it Encounters Sgr A*

PI Name: Daryl Haggard

A dense, cold cloud (G2) is on a collision course with Sgr A*, the radio source at our Galactic Center. G2 is on an eccentric orbit and already shows signs of tidal disruption by the black hole. High-energy emission from Sgr A* will likely increase significantly due to this encounter, peaking at pericenter (summer 2013). We propose simultaneous Chandra, XMM, and EVLA monitoring observations to constrain the rates and emission mechanisms of faint X-ray flares, study the radiation properties of Sgr A* as G2 breaks up and feeds gas to the central accretion flow, and detect G2 itself as it is shocked and heated. Multiwavelength observations of this encounter will have a profound impact on our understanding of radiatively inefficient accretion flows into, and outflow from, massive black holes.

Title: C-GOALS: The Chandra-RBGS Survey of a Complete Sample of Major-Merger LIRGs

PI Name: David Sanders

We propose to finish our Chandra-ACIS survey of a statistically complete sample of 87 major-merger LIRGs [log(Lir/Lsun)=11.0-12.57], from the IRAS RBGS. Our proposed Cycle-14 observations of the 29 lower-luminosity objects (11.0-11.72) will allow us to have a uniform and complete census of AGN and X-ray luminous starbursts in the nearest and brightest major-merger LIRGs, and will complement our existing Spitzer-IRAC/MIPS/IRS, HST-ACS, GALEX and Herschel observations of the same sample. The results will be used to address the following key questions: are binary AGN a common feature of these LIRGs, and if so, when and at what level is the AGN activity triggered in each nucleus? And can the fueling and growth of massive black holes be correlated in time with the merger phase?

Title: A High-Resolution View of the Warm Absorber and Iron Line in Mrk 1040

PI Name: Andrew Lobban

Mrk 1040 is a nearby type-1 Seyfert galaxy where a recent XMM observation revealed the presence of a deep soft X-ray warm absorber. However the current data are unable to resolve the components of the absorber so very little is known about its properties. We propose to obtain a 200 ks definitive Chandra HETG observation of Mrk 1040 from 0.5-9.0 keV where we will resolve the lines for the first time enabling a detailed analysis of the kinematics and energetics to be made. We will also obtain the first high-resolution spectrum > 2 keV in this source allowing us to resolve the narrow Fe K alpha core. Furthermore, through a 125 ks Suzaku observation we will also study the Fe K complex in unprecedented detail while simultaneously determining the origin of the hard excess.

Title: Arp 299: a case study of one of the most luminous star-forming galaxies

PI Name: Andreas Zezas

We propose a 100ksec ACIS-S observation of Arp299 the second most X-ray luminous starburst galaxy in the local Universe. Short XMM and Chandra observations showed: one (and possibly two) AGN(s), a large population of ULXs and a luminous hot gaseous component. These characteristics together with its high star-formation rate make it one of the very few local analogs of high-z normal galaxies detected in deep X-ray surveys. This observation will allow us to: i) characterize the two nuclei and measure their contribution to the energy output of the system; ii) study its population of X-ray sources, providing a benchmark for the ULX populations at very high SFR; iii) investigate the hot gaseous component associated with the system, possibly related with a galactic scale outflow.

Title: CGCG~298-021: X-ray counterpart to an Ultra High Energy Cosmic Ray source?

PI Name: Glennys Farrar

Discovering the astrophysical sources of Ultra-High Energy Cosmic Rays (UHECRs) is a great unsolved problem. The only known compact cluster of UHECRs (containing four events out of ~ 200) is consistent with being sourced by a Swift-BAT AGN, CGCG 291-028. This is highly significant given the uniqueness of this UHECR cluster and the absence of any other candidate source (of any kind) in the field. Spatial imaging with Chandra will constrain the location of the X-ray source with respect to the AGN and allow the ejection hypothesis to be tested. The X-ray spectrum from a 25~ks Chandra observation will go much deeper than the Swift-XRT spectrum, allowing a good measurement of the X-ray luminosity and spectral energy distribution, crucial for constraining the UHECR acceleration mechanism.

Title: X-ray monitoring of Sgr A* during outburst

We propose to trigger a 100ks HETG observation, followed by a monitoring campaign of several 45 or 30ks HETG observations (depending on the source flux level), if an outburst L_SgrA*>10^36 erg s-1 from the super-massive Black Hole SgrA* is observed. In these conditions SgrA* will be the brightest AGN in the 3-10 keV sky. This study will open new avenues in our understanding of accretion onto Black Holes.
