The initial mass function of early-type galaxies
T. Treu, M. W. Auger, L. V. E. Koopmans +3
We determine an absolute calibration of the initial mass function (IMF) of early-type galaxies, by studying a sample of 56 gravitational lenses identified by the SLACS Survey. Unde…
The Sloan Lens ACS Survey. IX. Colors, Lensing and Stellar Masses of Early-type Galaxies
M. W. Auger, T. Treu, A. S. Bolton +5
We present the current photometric dataset for the Sloan Lens ACS (SLACS) Survey, including HST photometry from ACS, WFPC2, and NICMOS. These data have enabled the confirmation of…
Cosmic Evolution of Virial and Stellar Mass in Massive Early-Type Galaxies
David J. Lagattuta, Christopher D. Fassnacht, Matthew W. Auger +7
We measure the average mass properties of a sample of 41 strong gravitational lenses at moderate redshift (z ~ 0.4 - 0.9), and present the lens redshift for 6 of these galaxies for…
Detection of a Dark Substructure through Gravitational Imaging
S. Vegetti, L. V. E. Koopmans, A. Bolton +2
We report the detection of a dark substructure through direct gravitational imaging - undetected in the HST-ACS F814W image - in the gravitational lens galaxy of SLACS SDSSJ0946+10…
Cluster and cluster galaxy evolution history from IR to X-ray observations of the young cluster RX J1257.2+4738 at z=0.866
M. P. Ulmer, C. Adami, G. B. Lima Neto +8
The cosmic time around the z~1 redshift range appears crucial in the cluster and galaxy evolution, since it is probably the epoch of the first mature galaxy clusters. Our knowledge…
Strong Lensing as a Probe of the Mass Distribution Beyond the Einstein Radius. Mass & Light in SL2S J08544-0121, a Galaxy Group at z=0.35
Marceau Limousin, Eric Jullo, Johan Richard +6
Precise modelling of strong lensing systems can be affected by external mass distributions, e.g. the group or cluster within which the lens is embedded. In this article, we propose…
