Electric Penrose process: high-energy acceleration of ionized particles by non-rotating weakly charged black hole
Arman Tursunov, Bakhtinur Juraev, Zdeněk Stuchlík +1
In many astrophysical scenarios the charge of the black hole is often neglected due to unrealistically large values of the charge required for the Reissner-Nordström spacetime metr…
Radiative Penrose process: Energy Gain by a Single Radiating Charged Particle in the Ergosphere of Rotating Black Hole
Martin Kološ, Arman Tursunov, Zdeněk Stuchlík
We demonstrate an extraordinary effect of energy gain by a single radiating charged particle inside the ergosphere of a Kerr black hole in presence of magnetic field. We solve nume…
Supermassive black holes as possible sources of ultra high energy cosmic rays
Arman Tursunov, Zdeněk Stuchlík, Martin Kološ +2
Production and acceleration mechanisms of ultra-high-energy cosmic rays (UHECRs) of energy eV, clearly beyond the GZK-cutoff limit remain unclear that points to exotic na…
Effect of Electromagnetic Interaction on Galactic Center Flare Components
Arman Tursunov, Michal Zajaček, Andreas Eckart +5
Recently, near-infrared GRAVITY@ESO observations at have announced the detection of three bright "flares" in the vicinity of the Galactic center supermassive black…
Multi-messenger signals from short gamma ray bursts
Agnieszka Janiuk, Kostas Sapountzis, Bestin James +1
We present the results of simulations done with the code HARM-COOL developed in the CTP PAS Warsaw research group over the years 2017-2019. It is based in the original GR MHD schem…
Determination of chaotic behaviour in time series generated by charged particle motion around magnetized Schwarzschild black holes
Radim Pánis, Martin Kološ, Zdeněk Stuchlík
We study behaviour of ionized region of a Keplerian disk orbiting a Schwarzschild black hole immersed in an asymptotically uniform magnetic field. In dependence on the magnetic par…
