The Structure & Dynamics of Massive Early-type Galaxies: On Homology, Isothermality and Isotropy inside one Effective Radius
L. V. E. Koopmans, A. Bolton, T. Treu +7
Based on 58 SLACS strong-lens early-type galaxies with direct total-mass and stellar-velocity dispersion measurements, we find that inside one effective radius massive elliptical g…
Strong gravitational lensing probes of the particle nature of dark matter
Leonidas A. Moustakas, Kevork Abazajian, Andrew Benson +44
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these ca…
The Sloan Lens ACS Survey. V. The Full ACS Strong-Lens Sample
Adam S. Bolton, Scott Burles, Leon V. E. Koopmans +5
We present the definitive data for the full sample of 131 strong gravitational lens candidates observed with the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope…
Numerical investigation of lenses with substructures using the perturbative method
Sébastien Peirani, Christophe Alard, Christophe Pichon +2
We present a statistical study of the effects induced by substructures on the deflection potential of dark matter halos in the strong lensing regime. This investigation is based on…
Late-time observations of SN2006gy: Still Going Strong
Nathan Smith, Ryan J. Foley, Joshua S. Bloom +9
Owing to its extremely high luminosity and long duration, SN2006gy radiated more energy in visual light than any other known SN. Two hypotheses to explain its high luminosity -- th…
The Sloan Lens ACS Survey. VI: Discovery and analysis of a double Einstein ring
Raphael Gavazzi, Tommaso Treu, Leon V. E. Koopmans +4
We report the discovery of two concentric Einstein rings around the gravitational lens SDSSJ0946+1006, as part of the Sloan Lens ACS Survey. The main lens is at redshift zl=0.222,…
