Mapping the Asymmetric Thick Disk: III. The Kinematics and Interaction with the Galactic Bar
Roberta M. Humphreys, Timothy C. Beers, Juan E. Cabanela +4
In the first two papers of this series, Larsen et al (2010a,b) describe our faint CCD survey in the inner Galaxy and map the over-density of Thick Disk stars in Quadrant I (Q1) to…
Near-infrared counterparts of Chandra X-ray sources toward the Galactic Center
Curtis DeWitt, Reba M. Bandyopadhyay, Stephen S. Eikenberry +4
The Chandra X-ray Observatory has now discovered nearly 10,000 X-ray point sources in the 2 x 0.8 degree region around the Galactic Center (Muno 2009). The sources are likely to be…
The Membership and Distance of the Open Cluster Collinder 419
Lewis C. Roberts, Douglas R. Gies, J. Robert Parks +6
The young open cluster Collinder 419 surrounds the massive O star, HD 193322, that is itself a remarkable multiple star system containing at least four components. Here we present…
A Hidden Population of Massive Stars with Circumstellar Shells Discovered with the Spitzer Space Telescope
S. Wachter, J. C. Mauerhan, S. D. Van Dyk +3
We have discovered a large number of circular and elliptical shells at 24 microns around luminous central sources with the MIPS instrument on-board the Spitzer Space Telescope. Our…
SDSS J1254+0846: A Binary Quasar Caught in the Act of Merging
Paul J. Green, Adam D. Myers, Wayne A. Barkhouse +5
We present the first luminous, spatially resolved binary quasar that clearly inhabits an ongoing galaxy merger. SDSS J125455.09+084653.9 and SDSS J125454.87+084652.1 (SDSS J1254+08…
Red Clump Stars in the Sagittarius Tidal Streams
Kenneth Carrell, Ronald Wilhelm, Yuqin Chen
We have probed a section (l ~ 150, b ~ -60) of the trailing tidal arm of the Sagittarius dwarf spheroidal galaxy by identifying a sample of Red Clump stream stars. Red Clump stars…
