Host Galaxies of Lensed Luminous Quasars at z~2
H. -W. Rix, E. Falco, C. Impey +5
We present H-band observations of gravitationally lensed QSO host galaxies obtained with NICMOS on HST as part of the CfA-Arizona-Gravitational-Lens-Survey (CASTLES). The detection…
The Evolution of Gravitational Lens Galaxies
C. S. Kochanek, E. E. Falco, C. D. Impey +6
Most gravitational lens galaxies are early-type galaxies in relatively low density environments. We show that they lie on the same fundamental plane as early-type galaxies in both…
The Interstellar Medium of Lens Galaxies
B. A. McLeod, E. E. Falco, C. S. Kochanek +6
We use observations from the CASTLES survey of gravitational lenses to study extinction in 23 lens galaxies with . The median differential extinction between lensed im…
The CASTLES gravitational lensing tool
E. E. Falco, C. S. Kochanek, J. Lehar +6
We describe a series of new applications of gravitational lenses as astrophysical and cosmological tools. Such applications are becoming possible thanks to advances in the quality…
A New Wide-Separation Gravitational Lens Candidate: RXJ 0921+4529
J. A. Munoz, E. E. Falco, C. S. Kochanek +8
The lens candidate RXJ 0921+4529 consists of two z_s=1.66 quasar separated by 6."93 with an H band magnitude difference of Δm=1.39. The lens appears to be a z_l=0.31 X-ray cluster,…
The Fundamental Plane of Gravitational Lens Galaxies and The Evolution of Early-Type Galaxies in Low Density Environments
C. S. Kochanek, E. E. Falco, C. D. Impey +6
Most gravitational lenses are early-type galaxies in relatively low density environments -- a ``field'' rather than a ``cluster'' population. We show that field early-type galaxies…
Finding Gravitational Lenses With X-rays
J. A. Munoz, C. S. Kochanek, E. E. Falco
There are , 0.1 and 0.01 gravitationally lensed X-ray sources per square degree with soft X-ray fluxes exceeding and respecti…
The Updated Zwicky Catalog (UZC)
Emilio E. Falco, Michael J. Kurtz, Margaret J. Geller +6
The Zwicky Catalog of galaxies (ZC), with m_Zw<=15.5mag, has been the basis for the Center for Astrophysics (CfA) redshift surveys. To date, analyses of the ZC and redshift surveys…
Spectral Energy Distributions and Light Curves of GRB 990123 and its Afterglow
T. J. Galama, M. S. Briggs, R. A. M. J. Wijers +38
Gamma-ray bursts (GRBs) are thought to result from the interaction of an extremely relativistic outflow interacting with a small amount of material surrounding the site of the expl…
The CASTLES project
J. A. Munoz, E. E. Falco, C. S. Kochanek +5
We describe the goals of the CASTLES (CfA-Arizona-Space-Telescope-LEns-Survey) project including a sample of NICMOS images of gravitational lenses and a brief list of the prelimina…
