Office of Scientific Computing
The Office of Scientific Computing designs, develops, and implements the computer systems required to process and analyze astrophysical data at the Astrophysics Science Division. The office supervises and performs the processing of all data through the final analysis phases. It manages all aspects of the Division's computer processing and serves as the focal point for all computer related matters, including information technology security. The office develops requirements for and monitors performance of all contracts for programming and data processing support services.

Multiwavelength Characterization of High Mass X-ray Binaries in Local Group Galaxies
Margaret Lazzarini (California State University, Los Angeles)
Multiwavelength observations of populations of evolved massive stellar binaries are crucial for understanding the complex process of massive binary stellar evolution. High mass X-ray binaries (HMXBs) are evolved massive stellar binaries in which the primary star has become a compact object and accretes from a massive secondary star. In this talk I will discuss ongoing work to characterize the population of HMXBs in massive spiral and low mass, dwarf galaxies in the Local Group. Combining deep optical and X-ray observations allows us to characterize each galaxy’s HMXB population including measuring X-ray luminosities, physical properties of the secondary stars, and the HMXB age distribution and production rate for each galaxy. These measured population demographics can be used to constrain theoretical binary stellar evolution models.
