Andromeda XXXV: The Faintest Dwarf Satellite of the Andromeda Galaxy

The Astrophysical Journal Letters
Abstract We present the discovery of Andromeda XXXV, the faintest Andromeda satellite galaxy discovered to date, identified as an overdensity of stars in the Pan-Andromeda Archaeological Survey and confirmed via Hubble Space Telescope imaging. Located at a heliocentric distance of

Stellar Populations in the Andromeda V Dwarf Spheroidal Galaxy

, 2008
Using archival imaging from the Wide Field Planetary Camera 2 aboard the Hubble Space Telescope, we investigate the stellar populations of the Local Group dwarf spheroidal Andromeda V - a companion satellite galaxy of M31.

On the accretion origin of a vast extended stellar disk around the Andromeda galaxy

, 2005
We present the discovery of an inhomogenous, low-surface brightness, extended disk-like structure around the Andromeda galaxy (M31) based on a large kinematic survey of more than 2800 stars with the Keck/DEIMOS spectrograph.

A dynamical model of the local cosmic expansion

, 2014
We combine the equations of motion that govern the dynamics of galaxies in the local volume with Bayesian techniques in order to fit orbits to published distances and velocities of galaxies within $\sim 3$ Mpc. We find a Local Group (LG) mass $2.3\pm 0.7\

A Deep Photometric Look at Two of Andromeda's Dwarf Spheroidals: X and XVII

, 2011
We use deep wide-field photometry from the Large Binocular Camera to study the stellar and structural properties of the recently discovered Andromeda X and Andromeda XVII (And X and And XVII) dwarf galaxies.
