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 کاملSpectral energy distribution of the γ - 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 کاملHigh-energy Γ-ray Emission from Microquasars: Ls 5039 and Ls I +61 303
The possible associations between the microquasars LS 5039 and LS I +61 303 and the EGRET sources 3EG J1824−1514 and 3EG J0241+6103 suggest that microquasars could also be sources of high-energy γ-rays. In this work, we present a detailed numerical inverse Compton (IC) model, based on a microquasar scenario, that reproduces the high-energy γ-ray spectra and variability observed by EGRET for the...
متن کاملMulti-wavelength (radio, X-ray and Γ-ray) Observations of the Γ-ray Binary Ls I +61 303
We present the results of the first multiwavelength observing campaign on the high-mass X-ray binary LS I +61303 comprising observations at the TeV regime with the MAGIC telescope, along with X-ray observations with Chandra, and radio interferometric observations with the MERLIN, EVN and VLBA arrays, in October and November 2006. From our MERLIN observations, we can exclude the existence of lar...
