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…

The Sloan Lens ACS Survey. VII. Elliptical Galaxy Scaling Laws from Direct Observational Mass Measurements

Adam S. Bolton, Tommaso Treu, Leon V. E. Koopmans +5

We use a sample of 53 massive early-type strong gravitational lens galaxies with well-measured redshifts (ranging from z=0.06 to 0.36) and stellar velocity dispersions (between 175…

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…

A More Fundamental Plane

Adam S. Bolton, Scott Burles, Tommaso Treu +2

We combine strong-lensing masses with SDSS stellar velocity dispersions and HST-ACS effective (half-light) radii for 36 lens galaxies from the Sloan Lens ACS (SLACS) Survey to stud…

The Sloan Lens ACS Survey. I. A Large Spectroscopically Selected Sample of Massive Early-Type Lens Galaxies

Adam S. Bolton, Scott Burles, Leon V. E. Koopmans +2

The Sloan Lens ACS (SLACS) Survey is an efficient Hubble Space Telescope Snapshot imaging survey for new galaxy-scale strong gravitational lenses. The targeted lens candidates are…

HST Observations of Heavy Elements in Metal-Poor Galactic Halo Stars

John J. Cowan, Christopher Sneden, Timothy C. Beers +6

We present new abundance determinations of neutron-capture elements Ge, Zr, Os, Ir, and Pt in a sample of 11 metal-poor (-3.1 <= [Fe/H] <= -1.6) Galactic halo giant stars, based on…
