Study of the Spectral and Temporal Characteristics of X-Ray Emission of the Gamma-Ray Binary LS 5039 with Suzaku
T. Takahashi, T. Kishishita, Y. Uchiyama +6
We report on the results from Suzaku broadband X-ray observations of the galactic binary source LS5039. The Suzaku data, which have continuous coverage of more than one orbital per…
Clues to unveil the emitter in LS 5039: powerful jets vs colliding winds
V. Bosch-Ramon, D. Khangulyan, F. A. Aharonian
LS 5039 is among the most interesting VHE sources in the Galaxy. Two scenarios have been put forward to explain the observed TeV radiation: jets vs pulsar winds. The source has bee…
Hydrodynamics of interaction of pulsar and stellar winds and its impact on the high energy radiation of binary pulsar systems
D. V. Khangulyan, F. A. Aharonian, S. V. Bogovalov +2
The hydrodynamics of the interaction of pulsar and stellar winds in binary systems harboring a pulsar and its impact on the nonthermal radiation of the binary pulsar PSR B1259-63/S…
A search for a dark matter annihilation signal towards the Canis Major overdensity with H.E.S.S
HESS Collaboration, F. Aharonian
A search for a dark matter (DM) annihilation signal into -rays toward the direction of the Canis Major (CMa) overdensity is presented. The nature of CMa is still controversial a…
The magnetic field and the location of the TeV emitter in Cygnus X-1 and LS 5039
V. Bosch-Ramon, D. Khangulyan, F. A. Aharonian
Cygnus X-1 and LS 5039 are two X-ray binaries observed at TeV energies. Both sources are compact systems, contain jet-like (radio) structures, and harbor very luminous O stars. A T…
Understanding the Very High-Energy Emission from Microquasars
Valenti Bosch-Ramon, Dmitry Khangulyan
Microquasars are X-ray binaries with relativistic jets. These jets are powerful energy carriers, thought to be fed by accretion, which produce non-thermal emission at different ene…
