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.

Multiwavelength Follow-up of the Hyperluminous Intermediate-mass Black Hole Candidate 3XMM J215022.4−055108 [PDF]
Astrophysical Journal, 2020 We recently discovered the X-ray/optical outbursting source 3XMM J215022.4−055108. It was best explained as the tidal disruption of a star by an intermediate-mass black hole of mass of a few tens of thousand solar masses in a massive star cluster at the ...

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

Intermediate mass black hole formation in compact young massive star clusters [PDF]
, 2020 Young dense massive star clusters are a promising environment for the formation of intermediate mass black holes (IMBHs) through collisions. We present a set of 80 simulations carried out with Nbody6++GPU of 10 initial conditions for compact $\sim 7 ...

Radio Emission from an Ultraluminous X-Ray Source [PDF]
, 2003 The physical nature of ultraluminous x-ray sources is uncertain. Stellar mass black holes with beamed radiation and intermediate mass black holes with isotropic radiation are two plausible explanations.

The Fifth Candidate for an Intermediate-mass Black Hole in the Galactic Center [PDF]
Astrophysical Journal, 2020 We report the results of high-resolution molecular line observations of the high-velocity compact cloud HCN–0.085–0.094 with the Atacama Large Millimeter/submillimeter Array. The HCN J = 4–3, HCO+ J = 4–3, and CS J = 7–6 line images reveal that HCN–0.085–

Looking for Intermediate-Mass Black Holes [PDF]
Nuclear Physics B - Proceedings Supplements, 2010 A discussion of the entropy of the universe leads to the suggestion of very many intermediate-mass black holes between thirty and three hundred thousand solar masses in the halo. It is consistent with observations on wide binaries as well as microlensing and considerations of disk stability that such IMBHs constitute all cold dark ...

Radio Detections During Two State Transitions of the Intermediate Mass Black Hole HLX-1 [PDF]
, 2012 Relativistic jets are streams of plasma moving at appreciable fractions of the speed of light. They have been observed from stellar mass black holes ($\sim$3$-$20 solar masses, M$_\odot$) as well as supermassive black holes ($\sim$10$^6$$-$10$^9$ M$_ ...

Does NGC 6397 contain an intermediate-mass black hole or a more diffuse inner subcluster? [PDF]
, 2020 We analyze proper motions from the Hubble Space Telescope (HST) and the second Gaia data release along with line-of-sight velocities from the MUSE spectrograph to detect imprints of an intermediate-mass black hole (IMBH) in the center of the nearby, core-
