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 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 kinematics and the origin of the ionized gas in NGC 4036
E. M. Corsini, F. Bertola, M. Sarzi +3
The kinematics of stars and ionized gas has been studied near the center of the S0 galaxy NGC 4036. Dynamical models based both on stellar photometry and kinematics have been built…
