Integral Serendipitous Detection of the Gamma-ray Microquasar Ls 5039
LS 5039 is the only X-ray binary persistently detected at TeV energies by the Cherenkov HESS telescope. It is moreover a γ-ray emitter in the GeV and possibly MeV energy ranges. To understand important aspects of jet physics, like the magnetic field content or particle acceleration, and emission processes, such as synchrotron and inverse Comp-ton (IC), a complete modeling of the multiwavelength...
متن کاملVERITAS observations of HESS J0632+057
HESS J0632+057 is one of only two unidentified high energy gamma-ray sources which appear to be point-like in nature. It is possibly associated with the massive star MWC 148 and has been suggested to resemble known TeV binary systems like LS I +61 303 or LS 5039. These binaries are rare and extreme (only three TeV binaries are known to date), and their gamma-ray emission mechanism has not been ...
متن کاملPulsar wind zone processes in LS 5039
Several γ-ray binaries have been recently detected by the High-Energy Stereoscopy Array (H.E.S.S.) and the Major Atmospheric Imaging Cerenkov (MAGIC) telescope. In at least two cases, their nature is unknown. In this paper we aim to provide the details of a theoretical model of close γ-ray binaries containing a young energetic pulsar as compact object, earlier presented in recent Letters. This ...
متن کاملEVN and MERLIN confirmation of the LS 5039 jets
The microquasar nature of LS 5039 was revealed by May 1999 VLBA+VLA observations showing a twosided jet at milliarcsecond scales. Here we present follow-up interferometric observations carried out with the EVN and MERLIN at 5 GHz in March 2000. The obtained maps with both the EVN and MERLIN show a two-sided jet with a similar position angle to the previous VLBA+VLA map. The total length of the ...
متن کاملVERITAS Observations of MGRO J1908+06/HESS J1908+063
The unidentified TeV gamma-ray source MGRO J1908+06/HESS J1908+063 was observed with the VERITAS Imaging Atmospheric Cherenkov Array during October 2007 and May-June 2008. This extended source is located on the galactic plane at a galactic longitude of 40.45 degrees and has a hard TeV spectrum with an index of Γ≈2.08 [1]. The Very High Energy (VHE) gamma-ray flux was measured by H.E.S.S. out to...
