Multiwavelength survey of X-ray sources in the Sculptor Dwarf Spheroidal Galaxy

R. M. Arnason, P. Barmby, A. Bahramian +2

We present an unprecedented, deep study of the primordial low-mass X-ray binary population in an isolated, lower-metallicity environment. We perform followup observations of previo…

Very Broad [O III]4959,5007 Emission from the NGC 4472 Globular Cluster RZ2109 and Implications for the Mass of Its Black Hole X-ray Source

Stephen E. Zepf, Daniel Stern, Thomas J. Maccarone +6

We present Keck LRIS spectroscopy of the black hole-hosting globular cluster RZ2109 in the Virgo elliptical galaxy NGC 4472. We find that this object has extraordinarily broad [OII…

Gemini/GMOS Imaging of Globular Clusters in the Virgo Galaxy NGC 4649 (M60)

Duncan A. Forbes, Favio Raul Faifer, Juan Carlos Forte +6

We present Sloan g and i imaging from the GMOS instrument on the Gemini North telescope for the globular cluster (GC) system around the Virgo galaxy NGC 4649 (M60). Our three point…

Some Constraints On the Effects of Age and Metallicity on the Low Mass X-ray Binary Formation Rate

Arunav Kundu, Thomas J. Maccarone, Stephen E. Zepf +1

We have studied the low mass X-ray binary (LMXB) populations within and outside globular clusters (GC) in NGC 4365 and NGC 3115. Using published age and metallicity constraints fro…

Globular Cluster Systems of Elliptical Galaxies

Stephen E. Zepf, Keith M. Ashman

We review the observed properties of globular cluster systems and their implications for models of galaxy formation. Observations show that globular clusters form in gas-rich merge…
