Quantifying Kinematic Substructure in the Milky Way's Stellar Halo

Xiang-Xiang Xue, Hans-Walter Rix, Brian Yanny +13

We present and analyze the positions, distances, and radial velocities for over 4000 blue horizontal-branch (BHB) stars in the Milky Way's halo, drawn from SDSS DR8. We search for…

On the time variability of the star formation efficiency

R. Feldmann, N. Y. Gnedin

A star formation efficiency per free fall time that evolves over the life time of giant molecular clouds (GMCs) may have important implications for models of supersonic turbulence…

The SEGUE Stellar Parameter Pipeline. IV. Validation with an Extended Sample of Galactic Globular and Open Clusters

Jason P Smolinski, Young Sun Lee, Timothy C Beers +7

Spectroscopic and photometric data for likely member stars of five Galactic globular clusters (M3, M53, M71, M92, and NGC 5053) and three open clusters (M35, NGC 2158, and NGC 6791…

Constraining Dark Matter in Galactic Substructure

Eric J. Baxter, Scott Dodelson, Savvas M. Koushiappas +1

Detecting the dark matter annihilation signal from Galactic substructure, or subhalos, is an important challenge for high-energy gamma-ray experiments. In this paper we discuss det…

Statistical Properties of Blue Horizontal Branch Stars in the Spheroid: Detection of a Moving Group approximately 50 kpc from the Sun

Matthew J. Harrigan, Heidi Jo Newberg, Lee A. Newberg +4

A new moving group comprising at least four Blue Horizontal Branch (BHB) stars is identified at (l,b) = (65 deg, 48 deg). The horizontal branch at g0=18.9 magnitude implies a dista…

Starry Messages: Searching for Signatures of Interstellar Archaeology

Richard A. Carrigan

Searching for signatures of cosmic-scale archaeological artifacts such as Dyson spheres or Kardashev civilizations is an interesting alternative to conventional SETI. Uncovering su…

The Orbit of the Orphan Stream

Heidi Jo Newberg, Benjamin A. Willett, Brian Yanny +1

We use recent SEGUE spectroscopy and SDSS and SEGUE imaging data to measure the sky position, distance, and radial velocities of stars in the tidal debris stream that is commonly r…
