The Century Survey Galactic Halo Project III: A Complete 4300 deg^2 Survey of Blue Horizontal Branch Stars in the Metal-Weak Thick Disk and Inner Halo
Warren R. Brown, Timothy C. Beers, Ronald Wilhelm +4
We present a complete spectroscopic survey of 2414 2MASS-selected blue horizontal branch (BHB) candidates selected over 4300 deg^2 of the sky. We identify 655 BHB stars in this non…
Spectroscopic Determination of the Faint End of the Luminosity Function in the Nearby Galaxy Clusters A2199 and Virgo
Kenneth Rines, Margaret J. Geller
We report a new determination of the faint end of the galaxy luminosity function in the nearby clusters Virgo and Abell 2199 using data from SDSS and the Hectospec multifiber spect…
MMT Extremely Metal Poor Galaxy Survey I. An Efficient Technique to Identify Metal Poor Galaxies
Warren R. Brown, Lisa J. Kewley, Margaret J. Geller
We demonstrate a successful strategy for identifying extremely metal poor galaxies. Our preliminary survey of 24 candidates contains 10 metal poor galaxies of which 4 have 12+log(O…
Hypervelocity Stars III. The Space Density and Ejection History of Main Sequence Stars from the Galactic Center
Warren R. Brown, Margaret J. Geller, Scott J. Kenyon +2
We report the discovery of 3 new unbound hypervelocity stars (HVSs), stars traveling with such extreme velocities that dynamical ejection from a massive black hole (MBH) is their o…
--PhotoZ: Photometric Redshifts by Inverting the Tolman Surface Brightness Test
Michael J. Kurtz, Margaret J. Geller, Daniel G. Fabricant +2
Surface brightness is a fundamental observational parameter of galaxies. We show, for the first time in detail, how it can be used to obtain photometric redshifts for galaxies, the…
Minor Galaxy Interactions: Star Formation Rates and Galaxy Properties
Deborah Freedman Woods, Margaret J. Geller
We study star formation in a sample of 1204 galaxies in minor (| Δm_z | \geq 2) pairs and compact groups, drawn from the Sloan Digital Sky Survey Data Release 5 (SDSS DR5). We anal…
