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…
Radiative Properties of Magnetically-Arrested Disks
Fu-Guo Xie, Andrzej A. Zdziarski
Magnetically-arrested disks (MADs) appear when accretion flows are supplied with a sufficient amount of magnetic flux. In this work, we use results of magnetohydrodynamic simulatio…
Spectral and temporal properties of Compton scattering by mildly relativistic thermal electrons
Andrzej A. Zdziarski, Michal Szanecki, Juri Poutanen +2
We have obtained new solutions and methods for the process of thermal Comptonization. We modify the solution to the kinetic equation of Sunyaev \& Titarchuk to allow its applicatio…
Jets in the soft state in Cyg X-3 caused by advection of the donor magnetic field and unification with low-mass X-ray binaries
Xinwu Cao, Andrzej A. Zdziarski
The high-mass accreting binary Cyg X-3 is distinctly different from low-mass X-ray binaries (LMXBs) in having powerful radio and -ray emitting jets in its soft spectral state. H…
Combined Dark Matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, HESS, MAGIC and VERITAS
Louise Oakes, Celine Armand, Eric Charles +13
The search for Dark Matter (DM) has great potential to reveal physics beyond the Standard Model. As such, searches for evidence of DM particles are being carried out using a wide r…
Variable jet Lorentz factors can explain soft self-absorbed radio spectra of accreting black-holes
Andrzej A. Zdziarski
We study the effect of variable jet bulk Lorentz factors, i.e., either jet acceleration or deceleration, on partially synchrotron self-absorbed radio spectra from cores of radio-lo…
