Long-term Stability of Non-thermal X-ray Modulation in the Gamma-ray Binary Ls 5039
We report on long-term stability of X-ray modulation apparently synchronized with an orbital period of 3.9 days in the γ-ray binary LS 5039. Recent observations with the Suzaku satellite in the year 2007, which covered continuously more than one orbital period, have provided us with detailed characterization of X-ray flux and spectral shape as a function of orbital phase. Motivated by the resul...
متن کاملStudy of the Spectral and Temporal Characteristics of X-ray Emission of the Gamma-ray Binary Ls 5039 with Suzaku
We report on the results from Suzaku broadband X-ray observations of the galactic binary source LS 5039. The Suzaku data, which have continuous coverage of more than one orbital period, show strong modulation of the X-ray emission at the orbital period of this TeV gamma-ray emitting system. The X-ray emission shows a minimum at orbital phase ∼ 0.1, close to the so-called superior conjunction of...
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 کاملA numerical model for the γ - ray emission of the microquasar LS 5039
The possible association between the microquasar LS 5039 and the EGRET source 3EG J1824−1514 suggests that microquasars could also be sources of high-energy γ-rays. In this paper, we explore, with a detailed numerical model, if this system can produce the emission detected by EGRET (>100 MeV) through inverse Compton (IC) scattering. Our numerical approach considers a population of relativistic ...
