Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core gravitationally collapses inward upon itself, compressing to a point of zero volume and
accretion disksWe present results from a survey of the properties of the central black holes in nearby AGN. This shows that AGN radiating near Eddington are on average less massive now than at z-1.Stuart LumsdenJonathan Digby-NorthOlivia Jones...
Several black hole X-ray transients have a very long recurrence time, decades of years [2]. We interpret this as a marginal occurrence of a dwarf nova type disk instability in the cool outer accretion disk. We compute how the recurrence time varies with the mass overflow rate from the ...
[21]were found to rely on an overly optimistic model for the black hole accretion rate[22]and continue to be updated as our understanding of accretion improves[23]. Similarly, uncertainty in the modeling of the PBH merger rate has led to several revisions of the bounds from gravitational ...
Black hole mass and accretion rate of Active Galactic Nuclei Besides applying these relations in deriving black hole masses of various types of AGNs, we also employed the fundamental plane of elliptical galaxies to ... XB Wu,FK Liu,R Wang,... - 《Journal of the Korean Physical Society》 ...
A newly formed black hole may be directly identified if late-time accretion of material from the base of the ejected envelope generates a luminosity that is observable in the tail of the supernova light curve. In this work we estimate the rate at which events where the black hole ``emerges...
Coevolution of black hole accretion and star formation in galaxies up to z = 3.5 Aims. We study the coevolution between the black hole accretion rate (BHAR) and the star formation rate (SFR) in different phases of galax... R Carraro,G Rodighiero,P Cassata,... - EDP Sciences 被引量...

Charged Kiselev black holeaccretionAccretion of matter onto a compact is one of the interesting astrophysical processes. Here, we study the accretion of matter onto a charged Kiselev black hole. The problem of static and spherically symmetric accretion of a polytropic fluid is explored for the ...
Low accretion rates at the AGN cosmic downsizing epoch We estimate the black hole masses and Eddington ratios of an X-ray selected sample of AGN in the Chandra Deep Field South at z<1, probing the epoch... Babić,Ana; Miller,Lance; Jarvis,... - 《Astronomy & Astrophysics》 被引量: ...
