Modeling Targets and Optimal Frequencies for Imaging the Shadows of Nearby Supermassive Black Holes
The Astrophysical JournalHorizon-scale imaging of supermassive black holes has opened a new avenue for studying strong-field gravity and plasma physics in low-luminosity accretion flows.

Supermassive black holes with stellar companions
AIP Conference Proceedings, 1994 Low‐mass stars in close orbits around supermassive black holes in active galactic nuclei (AGN) may provide an important signature for testing the existence of supermassive black holes. Here we discuss how such systems can form by being ‘‘ground down’’ by their interaction with an AGN accretion disk and discuss the peculiarities of such binaries with ...

Supermassive black hole binaries at high energies [PDF]
, 2022 An accretion disk around a supermassive black hole may be strongly perturbed by the presence of a secondary black hole. Recent simulations have shown that, under certain conditions, the tidal torques exerted by the secondary black hole may open an ...

Constraints on alternatives to supermassive black holes [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2006 Abstract Observations of the centres of galaxies continue to evolve, and it is useful to take a fresh look at the constraints that exist on alternatives to supermassive black holes at their centres. We discuss constraints complementary to those of Maoz and demonstrate that an extremely wide range of other possibilities can be excluded ...

Physical Origin of the Dark Spot in the First Image of Supermassive Black Hole SgrA*
, 2022 We elucidate the physical origin of the dark spot in the image of supermassive black hole SgrA* presented very recently by the EHT collaboration. It is argued that this dark spot, which is noticeably smaller than the classical black hole shadow, is the ...

The Astrophysical JournalMany stellar-mass black holes (sBHs) are expected to orbit supermassive black holes at galactic centers. For galaxies with active galactic nuclei, it is likely that the sBHs reside in a disk.
