A Multiwavelength Study of High-mass Gamma-ray Binaries
Joel Coley (Howard University / NASA-GSFC)

In this talk, I will present a multiwavelength overview of High-mass Gamma-ray binaries (HMGBs), which consist of a compact object and a massive star orbiting their center of mass. Compared to the hundreds of X-ray binaries that are currently known, only nine HMGBs have been firmly identified. While we have witnessed in the last two decades a significant advancement of our understanding of these sources, the high-energy emission is only confirmed to be driven by an intrabinary shock between a rapidly spinning pulsar compact object and the wind of a massive star in only in three HMGBs (PSR B1259-63, PSR J2032+4127 and LS I+61 303). I will additionally present multiwavelength spectral and timing results of three High-mass Gamma-ray binaries 1FGL J1018.6-5856, LS 5039 and 4FGL J1405.1-6119 and discuss the synchrotron and inverse Compton emission driving their high-energy emission.
