Metallicities and Physical Conditions in Star-forming Galaxies at z~1.0-1.5
Xin Liu, Alice E. Shapley, Alison L. Coil +2
We present a study of the mass-metallicity (M-Z) relation and H II region physical conditions in a sample of 20 star-forming galaxies at 1.0<z<1.5 drawn from the DEEP2 Galaxy Redsh…
The Varied Fates of z~2 Star-forming Galaxies
Charlie Conroy, Alice E. Shapley, Jeremy L. Tinker +2
Star-forming galaxies constitute the majority of galaxies with stellar masses >10^10 M_Sun/h^2 at z~2 and dominate the star-formation rate density of the Universe at this early epo…
A Search for Stellar Populations in High Velocity Clouds
M. H. Siegel, S. R. Majewski, C. Gallart +3
We report the results of a photometric search for giant stars associated with the cores of four high velocity clouds (HVCs) -- two of which are compact HVCs -- using the Las Campan…
On the nature of the ring-like structure in the outer Galactic disk
Amina Helmi, Julio F. Navarro, Andres Meza +2
We examine the tidal disruption of satellite galaxies in a cosmological simulation of the formation of a disk galaxy in the CDM scenario. We find that the disruption of satellit…
Exploring Halo Substructure with Giant Stars III: First Results from the Grid Giant Star Survey and Discovery of a Possible Nearby Sagittarius Tidal Structure in Virgo
A. Kundu, S. R. Majewski, J. Rhee +14
We describe first results of a spectroscopic probe of selected fields from the Grid Giant Star Survey. Multifiber spectroscopy of several hundred stars in a strip of eleven fields…
Starcounts Redivivus. IV. Density Laws Through Photometric Parallaxes
M. H. Siegel, S. R. Majewski, I. N. Reid +1
In an effort to more precisely define the spatial distribution of Galactic field stars, we present an analysis of the photometric parallaxes of 70,000 stars covering nearly 15 squa…
