Properties of Galaxies Hosting X-ray Selected Active Galactic Nuclei in the Cl1604 Supercluster at z=0.9
Dale D. Kocevski, Lori M. Lubin, Brian C. Lemaux +4
To investigate the role of feedback from Active Galactic Nuclei (AGN) in driving the evolution of their host galaxies, we have carried out a study of the environments and optical p…
A shrinking Compact Symmetric Object: J11584+2450?
S. E. Tremblay, G. B. Taylor, J. F. Helmboldt +2
We present multi-frequency multi-epoch Very Long Baseline Array (VLBA) observations of J11584+2450. These observations clearly show this source, previously classified as a core-jet…
The Observatory for Multi-Epoch Gravitational Lens Astrophysics (OMEGA)
Leonidas A Moustakas, Adam J Bolton, Jeffrey T Booth +15
(abridged) The Observatory for Multi-Epoch Gravitational Lens Astrophysics (OMEGA) is a mission concept for a 1.5-m near-UV through near-IR space observatory that will be dedicated…
Automated detection of galaxy-scale gravitational lenses in high resolution imaging data
Philip J. Marshall, David W. Hogg, Leonidas A. Moustakas +4
Lens modeling is the key to successful and meaningful automated strong galaxy-scale gravitational lens detection. We have implemented a lens-modeling "robot" that treats every brig…
GRB 071003: Broadband Follow-up Observations of a Very Bright Gamma-Ray Burst in a Galactic Halo
D. A. Perley, W. Li, R. Chornock +26
The optical afterglow of long-duration GRB 071003 is among the brightest yet to be detected from any GRB, with R ~ 12 mag in KAIT observations starting 42 s after the GRB trigger,…
Chandra Observations of the Cl1604 Supercluster at z=0.9: Evidence for an Overdensity of Active Galactic Nuclei
Dale D. Kocevski, Lori M. Lubin, Roy Gal +3
We present the results of Chandra observations of the Cl1604 supercluster at z~0.9. The system is the largest structure mapped at redshifts approaching unity, containing at least e…
