Global Properties of M31's Stellar Halo from the SPLASH Survey. I. Surface Brightness Profile

Karoline M. Gilbert, Puragra Guhathakurta, Rachael L. Beaton +10

We present the surface brightness profile of M31's stellar halo out to a projected radius of 175 kpc. The surface brightness estimates are based on confirmed samples of M31 red gia…

Detailed Abundances of Two Very Metal-Poor Stars in Dwarf Galaxies

Evan N. Kirby, Judith G. Cohen

The most metal-poor stars in dwarf spheroidal galaxies (dSphs) can show the nucleosynthetic patterns of one or a few supernovae. These supernovae could have zero metallicity, makin…

The Bizarre Chemical Inventory of NGC 2419, An Extreme Outer Halo Globular Cluster

Judith G. Cohen, Evan N. Kirby

We present new Keck/HIRES observations of six red giants in the globular cluster NGC 2419. Although the cluster is among the most distant and most luminous in the Milky Way, it was…

Two Distant Halo Velocity Groups Discovered by the Palomar Transient Factory

B. Sesar, J. G. Cohen, D. Levitan +8

We report the discovery of two new halo velocity groups (Cancer groups A and B) traced by 8 distant RR Lyrae stars and observed by the Palomar Transient Factory (PTF) survey at R.A…

The Dynamics and Metallicity Distribution of the Distant Dwarf Galaxy VV124

Evan N. Kirby, Judith G. Cohen, Michele Bellazzini

VV124 (UGC 4879) is an isolated, dwarf irregular/dwarf spheroidal (dIrr/dSph) transition-type galaxy at a distance of 1.36 Mpc. Previous low-resolution spectroscopy yielded inconsi…
