Journal ArticleDOI

Constraints on the equation of state of dark energy and the Hubble constant from stellar ages and the CMB

TL;DR: In this article, the relative ages of the oldest galaxies in the universe as a function of redshift, dz/dt, were calculated from SDSS galaxies and an independent estimate for the Hubble constant, H_0 = 69 \pm 12 km s-1 Mpc-1.
Journal ArticleDOI

Massive Dark Matter Halos and Evolution of Early-Type Galaxies to z ~ 1

TL;DR: In this article, the authors presented new observations and models of three lens systems (CFRS 03.1077, HST 14176+5226, and HST 15433+5352) and the combined results from the five field E/S0 lens galaxies at z ≈ 0.5-1.0 analyzed as part of the Lenses Structure and Dynamics (LSD) Survey.
Journal ArticleDOI

Dissecting the Gravitational lens B1608+656. II. Precision Measurements of the Hubble Constant, Spatial Curvature, and the Dark Energy Equation of State

TL;DR: In this article, a Bayesian analysis of the strong gravitational lens system B1608+656 is presented, incorporating new, deep Hubble Space Telescope (HST) observations, a new velocity-dispersion measurement of 260 ± 15 km s-1 for the primary lens galaxy, and an updated study of the lens' environment.
