Spectral energy distribution of the gamma-ray microquasar LS 5039
J. M. Paredes, V. Bosch-Ramon, G. E. Romero
The microquasar LS 5039 has recently been detected as a source of very high energy (VHE) -rays. This detection, that confirms the previously proposed association of LS 5039 with…
A broadband leptonic model for gamma-ray emitting microquasars
V. Bosch-Ramon, G. E. Romero, J. M. Paredes
Observational and theoretical studies point to microquasars (MQs) as possible counterparts of a significant fraction of the unidentified gamma-ray sources detected so far. At prese…
Orbital X-Ray Variability of the Microquasar LS 5039
V. Bosch-Ramon, J. M. Paredes, M. Ribo +3
The properties of the orbit and the donor star in the high mass X-ray binary microquasar LS 5039 indicate that accretion processes should mainly occur via a radiatively driven wind…
A possible black hole in the gamma-ray microquasar LS 5039
J. Casares, M. Ribo, I. Ribas +3
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 physic…
Orbital Parameters of the Microquasar LSI +61 303
J. Casares, I. Ribas, J. M. Paredes +2
New optical spectroscopy of the HMXB microquasar LSI +61 303 is presented. Eccentric orbital fits to our radial velocity measurements yield updated orbital parameters in good agree…
High energy processes in microquasars
Josep M. Paredes
Microquasars are X-ray binary stars with the capability to generate relativisticjets. It is expected that microquasars are gamma-ray sources, because of the analogy with quasars an…
