Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry
suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these …

Galaxy masses play a fundamental role in our understanding of structure formation models.
This review addresses the variety and reliability of mass estimators that pertain to stars, gas …

We study the volume-limited and nearly mass-selected (stellar mass M stars≳ 6× 109 M⊙)
ATLAS3D sample of 260 early-type galaxies (ETGs, ellipticals Es and lenticulars S0s). We …

We investigate the well-known correlations between the dynamical mass-to-light ratio (M/L)
and other global observables of elliptical (E) and lenticular (S0) galaxies. We construct two …

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

As part of a research program exploring how and why dwarf elliptical (dE) galaxies depart
from the fundamental plane defined by luminous elliptical (E) galaxies, we have analyzed …

We use HST/WFC3 imaging from the CANDELS Multi-Cycle Treasury Survey, in conjunction
with the Sloan Digital Sky Survey, to explore the evolution of galactic structure for galaxies …

Based on 58 SLACS strong-lens early-type galaxies (ETGs) with direct total-mass and stellar-
velocity dispersion measurements, we find that inside one effective radius massive elliptical …

The combination of gravitational lensing and stellar dynamics breaks the mass-anisotropy
degeneracy and provides stringent constraints on the distribution of luminous and dark …

The tidal disruption of a star by a massive black hole is expected to yield a luminous flare of
thermal emission. About two dozen of these stellar tidal disruption flares (TDFs) may have …
