Some Aspects of Intermediate mass black holes
, 2007 There is a lot of current astrophysical evidence and interest in intermediate mass black holes, ranging from a few hundred to several thousand solar masses. The active galaxy M82 and the globular cluster in M31, for example, are known to host such objects.

Machine Learning Confirms GW231123 is a “Lite” Intermediate Mass Black Hole Merger
The Astrophysical Journal LettersThe LIGO–Virgo–KAGRA Collaboration recently reported GW231123, a black hole merger with total mass of around 190–265 M _⊙ . This event adds to the growing evidence of “lite” intermediate mass black hole (IMBH) discoveries of postmerger black holes ≳100 M

Formation Scenarios for Intermediate-Mass Black Holes
AIP Conference Proceedings, 2003 Black holes with hundreds to thousands of solar masses are more massive than can be formed from a single star in the current universe, yet the best candidates for these objects are not located in gas-rich environments where gradual accretion could build up the mass. Three main formation scenarios have been suggested in the literature: that intermediate-

Little Red Dots Are Tidal Disruption Events in Runaway-collapsing Clusters
The Astrophysical Journal LettersI hypothesize a physical explanation for the “little red dots” (LRDs) discovered by the James Webb Space Telescope (JWST). The first star formation in the Universe occurs in dense clusters, some of which may undergo runaway collapse and form an ...

The formation of intermediate mass black holes [PDF]
Symposium - International Astronomical Union, 2003 We study the growth rate of stars in dense star clusters by stellar collisions. Our analytic calculations are in good agreement with direct N-body simulations with up to 65536 stars performed on the GRAPE family of computers. We find that star clusters with a half mass relaxation time ≲ 20 Myr are dominated by stellar collisions.

Intermediate-mass Black Hole Progenitors from Stellar Collisions in Dense Star Clusters
The Astrophysical JournalVery massive stars (VMSs) formed via a sequence of stellar collisions in dense star clusters have been proposed as the progenitors of massive black hole seeds.

Probing Jet Compositions with Extreme Mass Ratio Binary Black Holes
UniverseDetermining whether black hole jets are dominated by leptonic or baryonic matter remains an open question in high-energy astrophysics. We propose that extreme mass ratio binary (EMRB) black holes, where an intermediate mass secondary black hole (a ...

Intermediate Mass Ratio Inspirals in Milky Way Galaxies
The Astrophysical JournalA consequence of a nonzero occupation fraction of massive black holes (MBHs) in dwarf galaxies is that these MBHs can become residents of larger galaxy halos via hierarchical merging and tidal stripping.

Prospects for Revealing Intermediate-mass Black Holes in NGC 1399 Using SKA
The Astrophysical JournalThis study investigates the detectability of intermediate-mass black holes (IMBHs) within the mass range 10 ^2 M _⊙ ≤ M _BH ≤ 10 ^5 M _⊙ in the globular star clusters of NGC 1399 at a frequency of 300.00 MHz.
