Supermassive black holes: Coevolution (or not) of black holes and host galaxies [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractSupermassive black holes (BHs) have been found in 75 galaxies by observing spatially resolved dynamics. The Hubble Space Telescope (HST) revolutionized BH work by advancing the subject from its ‘proof of concept’ phase into quantitative studies of BH demographics.

Black hole entropy and models [PDF]
, 1997 No universally accepted statistical explanation of black hole entropy exists up to now, therefore, it is worth another try. Admittedly, black hole entropy does not have to have a statistical origin. If the "black hole entropy" is called "black hole index"

High-energy signatures of binary supermassive black holes
EPJ Web of Conferences, 2013 Some active galactic nuclei are supposed to harbor binary systems of supermassive black holes. They are an attractive target for gravitational wave experiments.

, 2013 We present a new type of observation relating the gravitational wave emission of supermassive black hole mergers to their electromagnetic counterparts. This dual emission involves variability of a relativistic jet arising from the spin-orbit precession ...

Primordial Origins of Supermassive Black Holes [PDF]
, 2019 At the center of the Milky Way sits a supermassive black hole named Sagittarius A*1, which is over a million times the mass of our sun. Other galaxy centers host similar black holes which are up to thousands of times larger than even Sagittarius A*. Some

The Astrophysical JournalAccretion supermassive black holes in the center of active galaxies usually produce “jet”-collimated bipolar outflows of relativistic particles. Magnetic fields near the black hole event horizon may play a crucial role in the formation of jets/outflows ...
