ABSTRACT
We have reported the discovery of VHE gamma ray emission from the X-ray binary Cen X-3. We report further VHE observations of this object taken in 1998 and 1999. While these new data also show VHE gamma ray emission, no evidence of modulation at either the orbital or pulsar periods is found. © 2000 American Institute of Physics.

    With new generation VHE telescopes, X-ray binary systems become very promising targets for VHE γ-ray observations. In particular, if sources with relativistic jets are thought of as galactic analogues of AGNs, the acceleration mechanisms should be similar. We survey the prospects of studying...

    Cen X-3 is a well-studied high-mass accreting X-ray binary and a variable source of high energy gamma rays from 100 MeV to I TeV. The object has been extensively monitored with the University of Durham Mark 6 telescope. Results of observations, including those taken in 1998 and 1999, are...

    Evidence for orbital modulation of the very high energy (VHE) γ-ray emission from the high-mass X-ray binary and microquasar LS 5039 has recently been reported by the HESS collaboration. The observed flux modulation was found to go in tandem with a change in the GeV – TeV spectral...

    The recent detection of very-high-energy (GeV – TeV) γ-ray emission from the Galactic black-hole candidate and microquasar LS 5039 has sparked renewed interest in jet models for the high-energy emission in those objects. In this work, we have focused on models in which the high-energy...

    We discuss the implications of late flares following GRBs for determining the nature of the central engine. We argue that since the flare timescales are much longer than naturally expected for a stellar mass compact object, progenitor systems containing a non-compact star are favored for short...

    During our Swift/XRT program to obtain X-ray positions at arcsecond level for a sample of Galactic X-ray binaries, we discovered that SAX J0840.7+2248 is not a binary, but rather BeppoSAX/WFC+GRBM X-ray Rich GRB 980429. Here we report on this discovery and on the properties of this long, X-ray...

    The ongoing work of the IBIS Survey Team has produced regular catalogues of the source populations of the gamma-ray sky. The most recent, the 3rd IBIS/ISGRI Survey Catalogue (Bird et al. 2007), lists 68 confirmed High Mass X-ray binaries (HMXBs) as gamma-ray sources in the 20–100 keV...

    Three-dimensional numerical hydrodynamical modeling of a radiative wind and accretion disk in a close binary system with a compact object is carried out, using the massive X-ray binary LMC X-3 as an example. This system contains a precessing disk, and may have relativistic jets. These...
