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…
The Stellar and Gas Kinematics of the LITTLE THINGS Dwarf Irregular Galaxy NGC 1569
Megan Johnson, Deidre A. Hunter, Se-Heon Oh +5
In order to understand the formation and evolution of dIm galaxies, one needs to understand their three-dimensional structure. We present measurements of the stellar velocity dispe…
Stellar Kinematics of the Andromeda II Dwarf Spheroidal Galaxy
Nhung Ho, Marla C. Geha, Ricardo R. Munoz +7
We present kinematical profiles and metallicity for the M31 dwarf spheroidal (dSph) satellite galaxy Andromeda II (And II) based on Keck DEIMOS spectroscopy of 531 red giant branch…
Galaxies behind the Galactic plane: First results and perspectives from the VVV Survey
E. B. Amôres, L. Sodré, D. Minniti +8
Vista Variables in The Via Lactea (VVV) is an ESO variability survey that is performing observations in near infrared bands (ZYJHKs) towards the Galactic bulge and part of the disk…
A spectroscopic survey of Andromeda's Western Shelf
Mark A. Fardal, Puragra Guhathakurta, Karoline M. Gilbert +7
The Andromeda galaxy (M31) shows many tidal features in its halo, including the Giant Southern Stream (GSS) and a sharp ledge in surface density on its western side (the W Shelf).…
The Lick AGN Monitoring Project 2011: Dynamical Modeling of the Broad Line Region in Mrk 50
Anna Pancoast, Brendon J. Brewer, Tommaso Treu +33
We present dynamical modeling of the broad line region (BLR) in the Seyfert 1 galaxy Mrk 50 using reverberation mapping data taken as part of the Lick AGN Monitoring Project (LAMP)…
