Confirmation of persistent radio jets in the microquasar LS 5039
We present here new observations conducted with the EVN and MERLIN of the persistent microquasar LS 5039 discovered by Paredes et al. (2000) with the VLBA. The new observations confirm the presence of an asymmetric two-sided jet reaching up to ∼ 1000 AU on the longest jet arm. The results suggest a bending of the jets with increasing distance from the core and/or precession. The origin and loca...
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...
