AGN accretion disks as spatially resolved by polarimetry
Makoto Kishimoto, Robert Antonucci, Omer Blaes +4
A crucial difficulty in understanding the nature of the putative accretion disk in AGNs is that some of its key intrinsic spectral signatures cannot be observed directly. The stron…
Radiation-Dominated Disks Are Thermally Stable
Shigenobu Hirose, Julian H. Krolik, Omer Blaes
When the accretion rate is more than a small fraction of Eddington, the inner regions of accretion disks around black holes are expected to be radiation-dominated. However, in the…
The characteristic blue spectra of accretion disks in quasars as uncovered in the infrared
Makoto Kishimoto, Robert Antonucci, Omer Blaes +4
Quasars are thought to be powered by supermassive black holes accreting surrounding gas. Central to this picture is a putative accretion disk which is believed to be the source of…
Epicyclic Motions and Standing Shocks in Numerically Simulated Tilted Black-Hole Accretion Disks
P. Chris Fragile, Omer M. Blaes
This work presents a detailed analysis of the overall flow structure and unique features of the inner region of the tilted disk simulations described in Fragile et al. (2007). The…
