Constraining the charge of the Galactic centre black hole
Michal Zajaček, Arman Tursunov, Andreas Eckart +6
In this contribution, we summarize our results concerning the observational constraints on the electric charge associated with the Galactic centre black hole - Sgr A*. According to…
On the charge of the Galactic centre black hole
Michal Zajaček, Arman Tursunov, Andreas Eckart +1
The Galactic centre supermassive black hole (SMBH), in sharp contrast with its complex environment, is characterized by only three classical parameters -- mass, spin, and electric…
Orbital widening due to radiation reaction around a magnetized black hole
Arman Tursunov, Martin Kološ, Zdeněk Stuchlík
Radiation reaction acting on a charged particle moving at a stable circular orbit of a magnetized black hole can lead to the shift of the orbital radius outwards from the black hol…
The distinguishing signature of Magnetic Penrose Process
Naresh Dadhich, Arman Tursunov, Bobomurat Ahmedov +1
In this Letter, we wish to point out that the distinguishing feature of Magnetic Penrose process (MPP) is its super high efficiency exceeding (which was established in mid…
A stellar fly-by close to the Galactic centre: Can we detect stars on highly-relativistic orbits?
Michal Zajaček, Arman Tursunov
The Galactic centre Nuclear Star Cluster is one of the densest stellar clusters in the Galaxy. The stars in its inner portions orbit the supermassive black hole associated with com…
Radiation reaction of charged particles orbiting magnetized Schwarzschild black hole
Arman Tursunov, Martin Kološ, Zdeněk Stuchlík +1
In many astrophysically relevant situations radiation reaction force acting upon a charge can not be neglected and the question arises about the location and stability of circular…
