Combining Strong and Weak Gravitational Lensing in Abell 1689
M. Limousin, J. Richard, E. Jullo +14
We present a reconstruction of the mass distribution of galaxy cluster Abell 1689 at z = 0.18 using detected strong lensing features from deep HST/ACS observations and extensive gr…
Truncation of galaxy dark matter halos in high density environments
M. Limousin, J. P. Kneib, S. Bardeau +5
Our aim is to constrain the properties of dark matter halos inhabiting high density environments, such as is the case in massive galaxy clusters. We use galaxy-galaxy lensing techn…
A New Survey for Giant Arcs
Joseph F. Hennawi, Michael D. Gladders, Masamune Oguri +11
We report on the first results of an imaging survey to detect strong gravitational lensing targeting the richest clusters selected from the photometric data of the Sloan Digital Sk…
Strong lensing statistics in large, z~<0.2 surveys: bias in the lens galaxy population
Ole Moeller, Manfred Kitzbichler, Priyamvada Natarajan
We calculate the expected lensing statistics of the galaxy population in large, low-redshift surveys. Galaxies are modeled using realistic, multiple components: a dark matter halo,…
The Virial Mass Function of Nearby SDSS Galaxy Clusters
Kenneth Rines, Antonaldo Diaferio, Priyamvada Natarajan
We present a new determination of the cluster mass function and velocity dispersion function in a volume Mpc using the Fourth Data Release of the Sloan Digital…
Substructure and the Cusp and Fold Relations
Amir Babak Aazami, Priyamvada Natarajan
Gravitational lensing of a background source by a foreground galaxy lens occasionally produces four images of the source. The cusp and the fold relations impose conditions on the r…
