Polarization of light from warm clouds above an accretion disk: effects of strong-gravity near a black hole
J. Horak, V. Karas
We study polarization from scattering of light on a cloud in radial motion along the symmetry axis of an accretion disk. Radiation drag from the disk and gravitational attraction o…

Of NBOs and kHz QPOs: a low-frequency modulation in resonant oscillations of relativistic accretion disks
J. Horak, M. Abramowicz, V. Karas +1
The origin of quasi periodic modulations of flux in the kilohertz range (kHz QPOs), observed in low-mass X-ray binaries, is usually assumed to be physically distinct from that of t…
