The Lenses Structure & Dynamics Survey: The internal structure and evolution of E/S0 galaxies and the determination of H0 from time-delay systems
L. V. E. Koopmans, T. Treu
Abstract
The Lenses Structure & Dynamics (LSD) Survey aims at studying the internal structure of luminous and dark matter - as well as their evolution - of field early-type (E/SO) galaxies to z~1. In particular, E/S0 lens galaxies are studied by combining gravitational lensing, photometric and kinematic data obtained with ground-based (VLA/Keck/VLT) and space-based telescopes (HST). Here, we report on preliminary results from the LSD Survey, in particular on (i) the constraints set on the luminous and dark-matter distributions in the inner several Reff of E/S0 galaxies, (ii) the evolution of their stellar component and (iii) the constraints set on the value of H0 from time-delay systems by combining lensing and kinematic data to break degeneracies in gravitational-lens models.
