BH AND NS BINARIES
Proposal Title: COMPLETE COMPACT OBJECT AND BINARY SURVEY OF 47TUC
PI: DR. JONATHAN E. GRINDLAY
Our cycle 1 observation of 47Tuc has shown its promise as the ultimate
laboratory for study of the production and evolution of compact binaries and co
mpact objects in globular clusters. We propose a deep (4 x 75ksec) ACIS-S obser
vation to measure the complete populations of millisecond pulsars (MSPs) and ca
taclysmic variables (CVs) by their variability and spectra and to constrain the
main sequence binary population. Coordinated HST (ACS) data would provide uniq
ue identifications of CVs and many MSPs and allow the full population of quiesc
ent low mass x-ray binaries to be distinguished from CVs. This dataset would pr
ovide fundamental constraints for the origins of neutron stars, millisecond pul
sars, magnetic white dwarfs and compact binaries in globular clusters.

SN, SNR AND ISOLATED NS
Proposal Title: A CHANDRA SURVEY FOR COMPACT OBJECTS IN SUPERNOVA REMNANTS
PI: PROF. SHRINIVAS R. KULKARNI
Observer: DAVID KAPLAN
It has become increasingly clear that the natal properties of young neu
tron stars exhibit a rich diversity --- dramatically illustrated by the enigmat
ic central object in Cas A and hinted at by early 3D modeling of core-collapse.
We propose a survey of an objectively constructed sample of nearby SNRs which,
when combined with archival data and our vigorous multi-wavelength observation
program, will give us a reliable view of the true variety of neutron stars. Th
e ensuing statistics and studies of the central objects will advance our unders
tanding of core-collapse and have bearing on related topics (supernova energeti
cs, natal kicks, etc). We believe that this comprehensive effort, a census of s
uch objects within 5 kpc, will be one of the enduring legacies of the Chandra m
ission.

NORMAL GALAXIES
Proposal Title: MONITORING THE EXTREME X-RAY FLARING OF SAGITTARIUS A* AND A DEEP
SURVEY OF THE CENTRAL 40 PC OF THE GALAXY
PI: DR. FREDERICK K. BAGANOFF
In Cycle 1, we discovered the first clear evidence of X-ray emission fr
om Sgr A*, the compact radio source associated with the massive black hole (MBH
) at the dynamical center of the Milky Way. In Cycle 2, we made the first detec
tion of rapid, large-amplitude X-ray variability of Sgr A*. To gather unprecede
nted information about the immediate environment of an MBH, we propose a 510-ks
ACIS-I observation of Sgr A* to measure the quiescent-state emission spectrum
and to characterize the timescales, duty cycle, energetics, and spectral evolut
ion of the flares. Simultaneous monitoring with OVRO and VLBA are being propose
d to search for correlated variations and lags predicted by theory to character
ize the flaring state emission process. We will also obtain a deep survey in th
is rich field.

ACTIVE GALAXIES AND QUASARS
Proposal Title: AN IN-DEPTH STUDY OF THE X-RAY SOURCE POPULATION AND HOT ISM OF THE
ANTENNAE GALAXIES
PI: DR. GIUSEPPINA FABBIANO
We propose a deep 375~ks observation of the prototypical merger galaxie
s NGC~4038/39 (``The Antennae''), divided into 5 time segments. Together with t
he archival data, we will obtain a deep 450ks ACIS-S exposure and time monitori
ng over 3 yrs. The unique significance of the Antennae for our understanding of
mergers and the extraordinary characteristics of the X-ray emission of this sy
stem, make this study essential for probing a wide range of fundamental questio
ns on the properties and evolution of XRBs, the range of black hole masses impl
ied by the rich ULX population, the properties of the multiphase ISM, and the e
volution of galaxy mergers, that cannot be addressed by looking at more normal
galaxies.

ACTIVE GALAXIES AND QUASARS
Proposal Title: RESOLVING THE WARM ABSORBER IN NGC 5548
PI: DR. JELLE S. KAASTRA
We propose to map the ionization and velocity structure of the X-ray an
d UV absorbers in NGC 5548 with the LETGS and HETGS of Chandra and STIS/HST. NG
C 5548 is an important target for this kind of study because 1) it shows multip
le kinematic components in the UV characterized by a range in ionization parame
ter and effective column, 2) it shows evidence for multiple kinematic and ioniz
ation components in previous Chandra X-ray spectra, and 3) it has a low Galacti
c column, which permits coverage of spectral lines out to 80 Angstrom with the
LETGS. These data yield the ionization parameter and column density of the abso
rption-line regions as a function of radial velocity, and constrain the element
al abundances and shape of the unobserved EUV continuum.

CLUSTERS OF GALAXIES
Proposal Title: MACS: THE X-RAY PROPERTIES OF THE MOST MASSIVE GALAXY CLUSTERS AT
Z>0.3
PI: DR. HARALD EBELING
We propose ACIS-I and HST observations of 30 distant and very X-ray lum
inous clusters (z>0.3, Lx>1e45) detected in the MAssive Cluster Survey (MACS).
22 of these 30 are new discoveries. Our targets are the high-z counterparts of
the best-studied local systems and, combined with 4 others scheduled for observ
ation, form a statistical sample >10 times larger than any previous one in this
redshift and luminosity range. Chandra's unique capabilities will allow us to
obtain spatially resolved gas temperature and density maps to constrain both th
e cosmological and physical parameters governing the evolution of the most mass
ive clusters at z<0.5. The proposed observations are complemented by extensive
groundbased follow-up studies of weak gravitational lensing, galaxy dynamics an
d the SZ effect.

EXTRAGALACTIC DIFFUSE EMISSION AND SURVEYS
Proposal Title: THE CHANDRA SURVEY OF THE HUBBLE DEEP FIELD NORTH AREA: A PUBLIC
RESOURCE FOR THE PRESENT AND FUTURE OF X-RAY ASTRONOMY
PI: PROF. WILLIAM NIELSEN BRANDT
We propose to extend the Chandra deep survey of the HDF-N and its vicin
ity. The ultimate goal is to obtain 5 Ms of coverage over the next 5 years; cur
rently we have 1 Ms coverage. Here we propose two public 500 ks observations. T
his project will fulfill one of Chandra's central design goals and will be a lo
ng-lasting legacy of Chandra, laying the groundwork for the next generation of
X-ray observatories. We should remain nearly photon limited for point-sources n
ear the aim point. We will study obscured and high-redshift AGN, starbursts, no
rmal galaxies, clusters, groups, and diffuse X-ray emission. The HDF-N field is
the ideal region for multiwavelength follow-up studies due to the enormous dat
abase already in place. Our ACIS team expertise will be extensively utilized.
