Observing an intermediate-mass black hole GW190521 with minimal assumptions [PDF]
, 2021 On May 21, 2019 the Advanced LIGO and Advanced Virgo detectors observed a gravitational-wave transient GW190521, the heaviest binary black-hole merger detected to date with remnant mass of 142 Mm that was published recently. This observation is the first

An intermediate‐mass black hole candidate in M51? [PDF]
Astronomische Nachrichten, 2016 AbstractWe present the current results of an investigation into M51 ULX‐7, using archival data from XMM‐Newton, Chandra and NuSTAR, and optical and radio data from HST and VLA. The source has a consistently hard power‐law X‐ray spectrum and high short‐term variability.

Accretion Into and Emission from Black Holes [PDF]
, 1976 Analyses are given of various processes involving matter falling into or coming out of black holes. A significant amount of matter may fall into a black hole in a galactic nucleus or in a binary system.

Discovery of a Planar Black Hole Mass Scaling Relation for Spiral Galaxies
The Astrophysical Journal Letters, 2023 Supermassive black holes (SMBHs) are tiny in comparison to the galaxies they inhabit, yet they manage to influence and coevolve along with their hosts.

Tidal disruption of white dwarfs by intermediate mass black holes
EPJ Web of Conferences, 2012 Modeling ultra-close encounters between a white dwarf and a spinning, intermediate mass black hole requires a full general relativistic treatment of gravity. This paper summarizes results from such a study.

The Astrophysical Journal, 2023 X-ray spectroscopy of Galactic black hole binaries serves as a powerful tool to gain an overall understanding of the system. Not only can the properties of the accretion disk be studied in detail, the fundamental properties of the black hole such as spin

An escaping outflow in a galaxy with an intermediate-mass black hole
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT While in massive galaxies active galactic nucleus (AGN) feedback plays an important role, the role of AGN feedback is still under debate in dwarf galaxies. With well spatially resolved data obtained from the Multi-Unit Spectroscopic Explorer, we identify a spatially extended ($\rm \sim 3\,\, kpc$) and fast ($V_{80} \sim 471\,\, \

Hypervelocity Stars from a Supermassive Black Hole–Intermediate-mass Black Hole Binary [PDF]
The Astrophysical Journal, 2019 Abstract In this paper we consider a scenario in which the currently observed hypervelocity stars in our Galaxy have been ejected from the Galactic center as a result of dynamical interactions with an intermediate-mass black hole (IMBH) orbiting the central supermassive black hole (SMBH).
