Magnetic layers and neutral points near rotating black hole
V. Karas, O. Kopacek
Magnetic layers are narrow regions where the field direction changes sharply. They often occur in the association with neutral points of the magnetic field. We show that an organis…

Thermal disc emission from a rotating black hole: X-ray polarization signatures
M. Dovciak, F. Muleri, R. W. Goosmann +2
Thermal emission from the accretion disc around a black hole can be polarized, due to Thomson scattering in a disc atmosphere. In Newtonian space, the polarization angle must be ei…

Hot-spot model for accretion disc variability as random process
T. Pechacek, V. Karas, B. Czerny
Theory of random processes provides an attractive mathematical tool to describe the fluctuating signal from accreting sources, such as active galactic nuclei and Galactic black hol…
