Outflows from naked singularities, infall through the black hole horizon: hydrodynamic simulations of accretion in the Reissner-Nordström space-time
Włodek Kluźniak, Tomasz Krajewski
We performed the first simulations of accretion onto the compact objects in the Reissner-Nordström (RN) spacetime. The results obtained in general relativity are representative of…
H.E.S.S. observations of the 2021 periastron passage of PSR B1259-63/LS 2883
H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +141
PSR B1259-63 is a gamma-ray binary system that hosts a pulsar in an eccentric orbit, with a 3.4 year period, around an O9.5Ve star. At orbital phases close to periastron passages,…
General Relativistic Magnetohydrodynamic Simulations of Accreting Tori: Resolution Study
Angelos Karakonstantakis, Debora Lančová, Włodek Kluźniak +1
We present two-dimensional general relativistic radiative magnetohydrodynamical simulations of accretion disks around non-rotating stellar-mass black hole. We study the evolution o…
Equilibrium tori orbiting Reissner-Nordström naked singularities
Ruchi Mishra, Włodek Kluźniak
In general relativity, the asymptotically flat space-time of a charged, spherically symmetric (non-rotating) body is described by the Reissner-Nordström metric. This metric corresp…
The peculiar new state of the blazar PKS 1510-089
H. M. Schutte, M. Zacharias, M. Böttcher +4
Contemporaneous multiwavelength observations with H.E.S.S., SALT, Fermi-LAT, Swift, and ATOM show that the blazar PKS 1510-089 suffered a significant decrease in its optical flux,…
Prospects for -ray observations of the Perseus galaxy cluster with the Cherenkov Telescope Array
The Cherenkov Telescope Array Consortium, :, K. Abe +564
Galaxy clusters are expected to be dark matter (DM) reservoirs and storage rooms for the cosmic-ray protons (CRp) that accumulate along the cluster's formation history. Accordingly…
