Observational signatures of misaligned double-ring and double-torus configurations around a Schwarzschild black hole
Dmitriy Ovchinnikov, Jan Schee, Zdeněk Stuchlík
We investigate the observational signatures of an idealized double-ring and double-torus system orbiting a Schwarzschild black hole, allowing the two emitting components to have mu…
Dynamical and observational properties of weakly Proca-charged black holes
Abylaikhan Tlemissov, Arman Tursunov, Jiří Kovář +1
The simplest approach to include a mass into the electromagnetic vector potential is to modify the Einstein-Maxwell action to the Einstein-Proca form. There are currently no exact…
Deterministic and Stochastic Study of the X-ray Emission from the TeV Blazar Mrk~421
Radim Pánis, Gopal Bhatta, Tek P. Adhikari +6
We present a comprehensive timing analysis of X-ray data from the {\it XMM-Newton} satellite, examining 50 light curves covering 17 years of observations of the blazar Mrk~421. Thi…
Radiative Back-Reaction on Charged Particle Motion in the Dipole Magnetosphere of Neutron Stars
Zdeněk Stuchlík, Jaroslav Vrba, Martin Kološ +1
The motion of charged particles under the Lorentz force in the magnetosphere of neutron stars, represented by a dipole field in the Schwarzschild spacetime, can be determined by an…
Light escape cones in the locally non-rotating reference frames of the Kerr-de Sitter superspinars and related superspinar shadows
Daniel Charbulák, Zdeněk Stuchlík
The construction of local escape cones and their complementary cones, related to the locally non-rotating frames (LNRFs) orbiting superspinars with the external field described by…
Radiating particle in the vicinity of the weakly charged Schwarzschild black hole
Bakhtinur Juraev, Zdeněk Stuchlík, Arman Tursunov +1
It is well known that supermassive black holes in the centers of galaxies are capable of accelerating charged particles to very high energies. In many cases, the particle accelerat…
