Infrared Spectroscopic Study of 8 Galactic Globular Clusters

Andrew W. Stephens, Jay A. Frogel

We have obtained medium-resolution infrared K band spectra of 44 giants in seven heavily reddened clusters in the Galactic bulge, as well as 12 giants in omega Centauri. We measure…

M-BH - sigma relation for a Complete Sample of Soft X-ray Selected AGNs

Dirk Grupe, Smita Mathur

We present black hole mass--bulge velocity dispersion relation for a complete sample of 75 soft X-ray selected AGNs: 43 broad line Seyfert 1s and 32 narrow line Seyfert 1s. We use…

The central image of a gravitationally lensed quasar

Joshua N. Winn, David Rusin, Christopher S. Kochanek

A galaxy can act as a gravitational lens, producing multiple images of a background object. Theory predicts there should be an odd number of images but, paradoxically, almost all o…

Survey for Transiting Extrasolar Planets in Stellar Systems: I. Fundamental Parameters of the Open Cluster NGC 1245

Christopher J. Burke, B. Scott Gaudi, D. L. DePoy +2

We derive fundamental parameters for the old, rich open cluster NGC 1245 using BVI photometry from the MDM 1.3m and 2.4m telescopes. Based on detailed isochrone fitting, we find NG…

The Supernova Relic Neutrino Backgrounds at KamLAND and Super-Kamiokande

Louis E. Strigari, Manoj Kaplinghat, Gary Steigman +1

We calculate the Supernova Relic Neutrino (SRN) background flux for the KamLAND and Super-Kamiokande (SK) detectors, motivated by the reduction in background at SK and new results…

Enhanced production of HD and D_2 molecules on small dust grains in diffuse clouds

Azi Lipshtat, Ofer Biham, Eric Herbst

Motivated by recent observations of deuterated molecules in the interstellar medium, we examine the production of HD and D molecules on dust grain surfaces. A mechanism for the…
