Revealing the intermediate-mass black hole at the heart of the dwarf galaxy NGC 404 with sub-parsec resolution ALMA observations [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2020
We estimate the mass of the intermediate-mass black hole at the heart of the dwarf elliptical galaxy NGC 404 using Atacama Large Millimetre/submillimetre Array (ALMA) observations of the molecular interstellar medium at an unprecedented linear ...

Study of the intermediate mass ratio black hole binary merger up to 1000:1 with numerical relativity [PDF]

open access: yesClassical and quantum gravity, 2022
We explicitly demonstrate that current numerical relativity techniques are able to accurately evolve black hole binaries with mass ratios of the order of 1000:1. This proof of principle is relevant for future third generation gravitational wave detectors

An intermediate‐mass black hole candidate in M51? [PDF]

open access: yesAstronomische 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.

The Nature of the IMBH Candidate CXO J133815.6+043255: High-frequency Radio Emission

open access: yesThe Astrophysical Journal, 2023
The ultraluminous X-ray source CXO J133815.6+043255 is a strong candidate for a bona fide intermediate-mass black hole residing in the outskirts of NGC 5252.

Investigating the mass of the intermediate mass black hole candidate HLX-1 with the SLIMBH model [PDF]

open access: yes, 2014
In this paper we present a comprehensive study of the mass of the intermediate mass black hole candidate HLX-1 in the galaxy ESO 243-49. We analyse the continuum X-ray spectra collected by Swift, XMM-Newton, and Chandra with the slim disc model, SLIMBH ...

Galactic Center IRS 13E: Colliding Stellar Winds or an Intermediate-mass Black Hole? [PDF]

open access: yesAstrophysical Journal, 2020
A small cluster of massive stars residing in the Galactic center, collectively known as IRS 13E, is of special interest due to its close proximity to the central supermassive black hole Sgr A* and the possibility that an embedded intermediate-mass black ...

Features of globular cluster’s dynamics with an intermediate-mass black hole

open access: yesOpen Astronomy, 2018
In this paper, we address the question of how a central intermediate-mass black hole (IMBH) in a globular cluster (GC) affects dynamics, core collapse, and formation of the binary population.

Soap Bubbles in Outer Space: Interaction of a Domain Wall with a Black Hole [PDF]

open access: yes, 1998
We discuss the generalized Plateau problem in the 3+1 dimensional Schwarzschild background. This represents the physical situation, which could for instance have appeared in the early universe, where a cosmic membrane (thin domain wall) is located near a

Star Clusters with Primordial Binaries: III. Dynamical Interaction between Binaries and an Intermediate Mass Black Hole [PDF]

open access: yes, 2006
We present the first study of the dynamical evolution of an isolated star cluster that combines a significant population of primordial binaries with the presence of a central black hole.
