TL;DR: In this paper, a 64-night spectroscopic monitoring campaign at the Lick Observatory 3m Shane telescope with the aim of measuring the masses of the black holes in 12 nearby (z < 0: 05) Seyfert 1 galaxies with expected masses in the range of 10 6 -10 7, and also the well-studied nearby active galactic nucleus (AGN) NGC 5548.

TL;DR: In this article, a 64-night spectroscopic monitoring campaign at the Lick Observatory 3m Shane telescope with the aim of measuring the masses of the black holes in 12 nearby (z < 0.05) Seyfert 1 galaxies with expected masses in the range ~10^6-10^7 M_sun and also the well-studied nearby active galactic nucleus (AGN) NGC 5548.
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.

Dissecting the Gravitational lens B1608+656. II. Precision Measurements of the Hubble Constant, Spatial Curvature, and the Dark Energy Equation of State
Sherry H. Suyu,Philip J. Marshall,Philip J. Marshall,Matthew W. Auger,Matthew W. Auger,Stefan Hilbert,Roger Blandford,Léon V. E. Koopmans,Christopher D. Fassnacht,Tommaso Treu,Tommaso Treu +10 more
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.
