A4_7 Supermassive (Interstellar) Black Hole [PDF]

open access: yes, 2014
This paper considers the plausibility of an event from the 2014 film Interstellar. It states that an hour on a planet orbiting a supermassive back hole is equivalent to 7 years passing on Earth.

Evolution of black hole shadow in the presence of ultralight bosons

open access: yesPhysics Letters B, 2020
Kerr black holes coupled to quantized bosonic fields display a special version of the Hawking effect, governed by the superradiance condition. This leads to rapid growth of boson cloud through spontaneous creation, leading to slowing down of the black ...

Modeling Targets and Optimal Frequencies for Imaging the Shadows of Nearby Supermassive Black Holes

open access: yesThe Astrophysical Journal
Horizon-scale imaging of supermassive black holes has opened a new avenue for studying strong-field gravity and plasma physics in low-luminosity accretion flows.

Formation of Merging Stellar-mass Black Hole Binaries by Gravitational-wave Emission in Active Galactic Nucleus Disks

open access: yesThe Astrophysical Journal
Many 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.

A supermassive black hole fundamental plane for ellipticals [PDF]

open access: yes, 2007
We obtain the coefficients of a new fundamental plane for supermassive black holes at the centers of elliptical galaxies, involving measured central black hole mass and photometric parameters that define the light distribution.

Enhancing the rate of tidal disruptions of stars by a self-gravitating disc around a massive central black hole

open access: yesEPJ Web of Conferences, 2012
We further study the idea that a self-gravitating accretion disc around a supermassive black hole can increase the rate of gradual orbital decay of stellar trajectories (and hence tidal disruption events) by setting some stars on eccentric trajectories ...
