Temperature Anisotropy of the CMBR and the Non-zero Cosmological Constant
Jan Schee, Evariste N. Boj
We analyze the effect of a spherically symmetric clump on the anisotropy of the cosmic microwave background radiation temperature in the framework of the standard model of cosmolog…
Timing of echoes in electromagnetic radiation from hot spots orbiting a Kerr black hole impostor
Sudipta Hensh, Jan Schee, Zdeněk Stuchlík
We investigate the light curve of an isolated bright spot in a Keplerian orbit around a Kerr black hole candidate to probe possible deviations from the standard event-horizon pictu…
Appearance of Keplerian discs orbiting on both sides of a reflection-symmetric wormhole
Jan Schee, Zdeněk Stuchík
We construct optical appearance and profiled spectral lines of Keplerian discs with inner edge at the innermost circular geodesic located on both sides of the reflection-symmetric…
Strong gravitational lensing around Kehagias-Sfetsos compact objects surrounded by plasma
Sudipta Hensh, Jan Schee, Ahmadjon Abdujabbarov +1
We present the analysis how Hořava gravity and plasma influence the strong lensing phenomena around Kehagias-Sfetsos (KS) black holes. Using the semi-analytical Bozza method of str…
Light curves of the hot spots on circular orbits around generic regular black holes related to non-linear electrodynamics with Maxwellian weak-field Limit
Dmitriy Ovchinnikov, Jan Schee, Zdenek Stuchlík +1
The combined effect of a strong gravitational field and electromagnetic field in the vicinity of a generic regular black hole related to non-linear electrodynamics with Maxwellian…
Shadow of the magnetically and tidally deformed black hole
R. A. Konoplya, Jan Schee, Dmitriy Ovchinnikov
We consider a simple model of a black hole surrounded by a toroidal structure and experiencing deformation due to magnetic field and the tidal force. For this system we construct t…
