A very-high-energy component deep in the Gamma-ray Burst afterglow
H. Abdalla R. Adam F. Aharonian F. Ait Benkhali E. O. Anguener M. Arakawa, C. Arcaro, C. Armand +219
Gamma-ray bursts (GRBs) are brief flashes of gamma rays, considered to be the most energetic explosive phenomena in the Universe. The emission from GRBs comprises a short (typicall…
Modelling the interaction between relativistic and non-relativistic winds in binary pulsar systems: strong magnetization of the pulsar wind
Sergey V. Bogovalov, Dmitry Khangulyan, Alexander V. Koldoba +2
We present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with the circumbinary environment. We focus on studying…
Detection of UHE gamma rays from the Crab Nebula: Physical Implications
Dmitry Khangulyan, Masanori Arakawa, Felix Aharonian
The Crab Nebula is an extreme particle accelerator boosting the energy of electrons up to a few PeV (), close to the maximum energy allowed by theory. The physica…
Multi-wavelength Emission from Galactic Jets: the Case of the Microquasar SS433
Takahiro Sudoh, Yoshiyuki Inoue, Dmitry Khangulyan
SS433 is a Galactic microquasar with powerful jets, where very-high-energy particles are produced. We study particle acceleration in the jets of SS433 in the light of the recent mu…
On the Origin of High Energy Neutrinos from NGC 1068: The Role of Non-Thermal Coronal Activity
Yoshiyuki Inoue, Dmitry Khangulyan, Akihiro Doi
NGC 1068, a nearby type-2 Seyfert galaxy, is reported as the hottest neutrino spot in the 10-year survey data of IceCube. Although there are several different possibilities for the…
On high-energy particles in accretion disk coronae of supermassive black holes: implications for MeV gamma rays and high-energy neutrinos from AGN cores
Yoshiyuki Inoue, Dmitry Khangulyan, Susumu Inoue +1
Recent observations with ALMA have revealed evidence for non-thermal synchrotron emission from the core regions of two nearby Seyfert galaxies. This suggests that the coronae of ac…
