Microquasar LS 5039: a TeV gamma-ray emitter and a potential TeV neutrino source
The recent detection of TeV γ-rays from the microquasar LS 5039 by HESS is one of the most exciting discoveries of observational gamma-ray astronomy in the very high energy regime. This result clearly demonstrates thatX-ray binaries with relativistic jets (microquasars) are sites of effective acceleration of particles (electrons and/or protons) to multi-TeV energies. Whether the γ-rays are of h...
متن کاملSpectral energy distribution of the gamma - ray microquasar LS 5039
The microquasar LS 5039 has recently been detected as a source of very high energy (VHE) γ-rays. This detection, that confirms the previously proposed association of LS 5039 with the EGRET source 3EG J1824−1514, makes of LS 5039 a special system with observational data covering nearly all the electromagnetic spectrum. In order to reproduce the observed spectrum of LS 5039, from radio to VHE γ-r...
متن کاملIntegral 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 کاملOn the magnetic field and the TeV emitter location in Cygnus X - 1 and LS 5039
Context. Cygnus X-1 and LS 5039 are two X-ray binaries detected at TeV energies. Both sources are compact systems, contain jetlike (radio) structures, and harbor very luminous O stars. The two systems show TeV signal around the superior conjunction of the compact object, when the largest gamma-ray opacities are expected. Aims. We investigate the implications of the TeV detections of Cygnus X-1 ...
متن کاملA possible black hole in the gamma - ray microquasar LS 5039
The population of high energy and very high energy gamma-ray sources, detected with EGRET and the new generation of ground-based Cherenkov telescopes, conforms a reduced but physically important sample. Most of these sources are extragalactic (e.g., blazars), while among the galactic ones there are pulsars and supernova remnants. The microquasar LS 5039, previously proposed to be associated wit...
