A New Method for the Reconstruction of Strongly Lensed Galaxies with Resolved Kinematics
Anthony J. Young, Charles R. Keeton, Andrew J. Baker
Integral field spectroscopy of high-redshift galaxies has become a powerful tool for understanding their dynamics and evolutionary states. However, in the case of gravitationally l…
The Impact of Baryonic Cooling on Giant Arc Abundances
Eduardo Rozo, Daisuke Nagai, Charles Keeton +1
Using ray tracing for simple analytic profiles, we demonstrate that the lensing cross section for producing giant arcs has distinct contributions due to arcs formed through image d…
Chandra Observations of SDSS J1004+4112: Constraints on the Lensing Cluster and Anomalous X-Ray Flux Ratios of the Quadruply Imaged Quasar
N. Ota, N. Inada, M. Oguri +15
We present results from Chandra observations of SDSS J1004+4112, a strongly lensed quasar system with a maximum image separation of 15". All four bright images of the quasar, as we…
Identifying Lenses with Small-Scale Structure. II. Fold Lenses
Charles R. Keeton, B. Scott Gaudi, A. O. Petters
When the source in a 4-image gravitational lens lies close to a "fold" caustic, two of the lensed images lie close together. If the lens potential is smooth on the scale of the sep…
Finite Source Effects in Strong Lensing: Implications for the Substructure Mass Scale
Gregory Dobler, Charles R. Keeton
Flux ratio `anomalies' in quadruply-imaged gravitational lenses can be explained with galactic substructure of the sort predicted by CDM, but the strength and uniqueness of that hy…
Gravitational lensing magnification without multiple imaging
Charles R. Keeton, Michael Kuhlen, Zoltan Haiman
Gravitational lensing can amplify the apparent brightness of distant sources. Images that are highly magnified are often part of multiply-imaged systems, but we consider the possib…
