The SPLASH Survey: Spectroscopy of 15 M31 Dwarf Spheroidal Satellite Galaxies
Erik J. Tollerud, Rachael L. Beaton, Marla C. Geha +13
We present a resolved-star spectroscopic survey of 15 dwarf spheroidal (dSph) satellites of the Andromeda Galaxy (M31) as part of the Spectroscopic and Photometric Landscape of And…
Very Early Ultraviolet and Optical Observations of the Type Ia Supernova 2009ig
Ryan J. Foley, P. J. Challis, A. V. Filippenko +18
Supernova (SN) 2009ig was discovered 17 hours after explosion by the Lick Observatory Supernova Search, promptly classified as a normal Type Ia SN (SN Ia), peaked at V = 13.5 mag,…
The Lick AGN Monitoring Project 2011: Reverberation Mapping of Markarian 50
A. J. Barth, A. Pancoast, S. J. Thorman +46
The Lick AGN Monitoring Project 2011 observing campaign was carried out over the course of 11 weeks in Spring 2011. Here we present the first results from this program, a measureme…
The Sagittarius impact as an architect of spirality and outer rings in the Milky Way
Chris W. Purcell, James S. Bullock, Erik Tollerud +2
Like many galaxies of its size, the Milky Way is a disk with prominent spiral arms rooted in a central bar, although our knowledge of its structure and origin is incomplete. Tradit…
Small-Scale Structure in the SDSS and LCDM: Isolated L* Galaxies with Bright Satellites
Erik J. Tollerud, Michael Boylan-Kolchin, Elizabeth J. Barton +2
We use a volume-limited spectroscopic sample of isolated galaxies in the Sloan Digital Sky Survey (SDSS) to investigate the frequency and radial distribution of luminous (M_r <~ -1…
