Accretion disks around kicked black holes: Post-kick Dynamics
Accretion disks kicked black holes: Post-kick Dynamics
font style='font-size:12px;'>
2011/9/29
Numerical calculations of merging black hole binaries indicate that asymmetric emission of gravitational radiation can kick the merged black hole at up to thousands of km/s, and a number of systems ha...
Can Self Organized Critical Accretion Disks Generate a Log-normal Emission Variability in AGN?

Active Galactic Nuclei (AGN), such as Seyfert galaxies, quasars, etc., show light variations in all wavelength bands, with various amplitude and in many time scales. The variations usually look errati...

Accretion disks in white dwarf systems are believed to be tilted. In a recent publication, the lift force has been suggested to be a source to disk tilt, a source that is likely relevant to all accret...

2010/12/22
We explore conditions and structure of accretion disks in short-period Cata- clysmic Variables (CVs), which have evolved beyond the period minimum. We show that accretion discs in systems with extreme...
