Galactic Centre stellar winds and Sgr A* accretion
J. Cuadra, S. Nayakshin, V. Springel +1
(ABRIDGED) We present in detail our new 3D numerical models for the accretion of stellar winds on to Sgr A*. In our most sophisticated models, we put stars on realistic orbits arou…
Accretion of cool stellar winds on Sgr A*: another puzzle of the Galactic Centre?
J. Cuadra, S. Nayakshin, V. Springel +1
Sgr A* is currently being fed by winds from a cluster of gravitationally bound young mass-loosing stars. Using observational constraints on the orbits, mass loss rates and wind vel…
Self-gravitating accretion disk in Sgr A* few million years ago: was Sgr A* a failed quasar?
Sergei Nayakshin, Jorge Cuadra
Sgr A* is extra-ordinarily dim in all wavelengths requiring a very low accretion rate at the present time. However, at a radial distance of a fraction of a parsec from Sgr A*, two…
Feeding the black hole with condensing accretion flows: radiatively efficient and radiatively inefficient cases
Sergei Nayakshin
We study the accretion flow of a hot gas captured by the black hole gravity in the presence of a thin cold accretion disk. Such geometrical arrangement is expected in Active Galact…
Ionization physics evidence for magnetic flare origin of X-rays in AGN
Sergei Nayakshin
We present full disk X-ray reflection spectra for two currently popular accretion flow geometries for AGN -- the lamppost model frequently used to discuss the iron line reverberati…
Corona Energy Budget in AGN and GBHCs
Sergei Nayakshin
Recent progress in observations and understanding of spectra of Seyfert Galaxies shows that X-rays are most likely produced by magnetic flares on the surface of the disk, similar t…
