Title: The Physics of the Jets of Powerful Radio Galaxies and Quasars

PI Name: Eric Perlman

We propose HST polarimetry and deep Chandra imaging of the jet of PKS 0637-752. This is thought to be the most Compton dominated quasar jet, and n ow that the IC/CMB model appears ruled out (thanks largely to our discovery of high optical polarization in the PKS 1136-135 jet), it provides an excellen t opportunity to test synchrotron models in the most extreme circumstances. While the synchrotron model does not require exceptionally fast flows (Gamma>3 0) at hundreds of kpc, tiny viewing angle (only a few degrees) and super-Eddington kinetic power, it does require particles to be accelerated up to tens o f TeV and hence radiative lifetimes as short as a few years. Additional Chandra observations will also look for spectral curvature and possible variabilit y in the X-rays.

Title: 2MASS J00423991+3017515: An AGN On The Run?

PI Name: James Hogg

We have discovered a peculiar AGN, 2MASS J00423991+3017515, in a local (z=0.14), disturbed galaxy whose optical spectrum has multiple broad lines that are consistently offset from the narrow line emission and host galaxy absorption by 1530 km/s. The morphology of the host galaxy and spectral propert ies thus suggest this AGN may be a recoiling supermassive black hole (SMBH). We propose high-resolution X-ray imaging and spectral follow-ups with the ACI S camera on Chandra to determine if the source of the kinematically-offset broad line emission is also spatially offset from the nucleus of the host galax y. If a single, spatially offset AGN is detected, this source will be strongest candidate for a recoiling AGN candidate discovered to date.
