VLBI imaging of the gravitational lenses B1422+231 and MGJ0414+0534
E. Ros, J. C. Guirado, J. M. Marcaide +5
We present wide-field images of the quadruple gravitational lenses B1422+231 and MGJ0414+0534 obtained from global Very Long Baseline Interferometry (VLBI) observations at 8.4 GHz…
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,…
