TL;DR: In this article, a transient behavior characterized by significant deficits in flux and equivalent width of the strong broad broad UV emission lines is identified in an active galactic nucleus reverberation mapping campaign, and two plausible mechanisms for the observed behavior are suggested: (i) temporary obscuration of the ionizing continuum incident upon BLR clouds by a moving veil of material lying between the inner accretion disk and inner BLR, or (ii) a temporary change in the intrinsic ionizing spectrum spectral energy distribution resulting in a deficit of ionizing photons with energies > 54 eV, possibly due to

TL;DR: In this paper, the authors present observational results from a new Hubble Space Telescope (HST) Snapshot program to extend the methods of the Sloan Lens ACS (SLACS) Survey to lower lens-galaxy masses.
Journal ArticleDOI
AMUSE-Field I: NUCLEAR X-RAY PROPERTIES OF LOCAL FIELD AND GROUP SPHEROIDS ACROSS THE STELLAR MASS SCALE
TL;DR: The first results from AMUSE-Field, a Chandra survey designed to characterize the occurrence and intensity of low-level accretion onto supermassive black holes (SMBHs) at the center of local early-type field galaxies are presented in this article.
Journal ArticleDOI
The mass assembly history of spheroidal galaxies : Did newly formed systems arise via major mergers?
TL;DR: In this article, the scaling relations between the dynamical mass M_(dyn), determined from stellar velocity dispersions, and the stellar mass M_*, determined from optical and infrared photometry were determined for a morphologically selected sample of 0.4 < z < 1.0 spheroidal galaxies in the GOODS fields.
