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…
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…
Non-thermal emission from secondary pairs in close TeV binary systems
V. Bosch-Ramon, D. Khangulyan, F. A. Aharonian
Massive hot stars produce dense ultraviolet (UV) photon fields in their surroundings. If a very high-energy (VHE) gamma-ray emitter is located close to the star, then gamma-rays ar…
Formation of hard VHE gamma-ray spectra of blazars due to internal photon-photon absorption
F. Aharonian, D. Khangulyan, L. Costamante
The energy spectra of TeV gamma-rays from blazars, after being corrected for intergalatic absorption in the Extragalactic Background Light (EBL), appear unusually hard, a fact that…
Modeling interaction of relativistic and nonrelativistic winds in binary system PSR 1259-63/SS2883. I.Hydrodynamical limit
S. V. Bogovalov, D. Khangulyan, A. V. Koldoba +2
In this paper, we present a detailed hydrodynamical study of the properties of the flow produced by the collision of a pulsar wind with the surrounding in a binary system. This wor…
