While the formation of the first black holes at high redshift is reasonably well understood though debated, massive black hole formation at later cosmic epochs has not been adequately explored. We present a gas accretion driven mechanism that can build up black hole masses rapidly in dense, gas-rich nuclear star clusters (NSCs). Wind-fed supra-exponential accretion of an initially wandering black hole in NSCs can lead to extremely fast growth, scaling stellar mass remnant seed black holes up to…

Growth of Stellar-mass Black Holes in Dense Molecular Clouds and GW190521

A stellar-mass black hole can grow its mass noticeably through Bondi accretion, if it is embedded in an extremely dense and massive molecular cloud with slow motion with respect to the ambient medium

Compact Binary Coalescences: Astrophysical Processes and Lessons Learned

On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct detection of gravitational waves, a signal caught by the LIGO interferometers on 14 September 2015, and

The Dawn of Black Holes

In the last decades, luminous accreting super-massive black holes have been discovered within the first Gyr after the Big Bang, but their origin is still an unsolved mystery. We discuss our

Merger Rates of Intermediate-mass Black Hole Binaries in Nuclear Star Clusters

Repeated mergers of stellar-mass black holes in dense star clusters can produce intermediate-mass black holes (IMBHs). In particular, nuclear star clusters at the centers of galaxies have deep enough

Massive Black Hole Formation in Dense Stellar Environments: Enhanced X-Ray Detection Rates in High-velocity Dispersion Nuclear Star Clusters

We analyze Chandra X-ray Observatory imaging of 108 galaxies hosting nuclear star clusters (NSCs) to search for signatures of massive black holes (BHs). NSCs are extremely dense stellar environments

Cosmological 21-cm line observations to test scenarios of super-Eddington accretion on to black holes being seeds of high-redshifted supermassive black holes

In this paper, we study scenarios of the super-Eddington accretion onto black holes at high redshifts z > 10, which are expected to be seeds to evolve to supermassive black holes until redshift z ∼

We demonstrate a single-parameter route for reproducing higher mass objects as observed in the LIGO–Virgo mass distribution, using only the isolated-binary stellar evolution channel. This single

The Active Fraction of Massive Black Holes in Dwarf Galaxies

The population of massive black holes (MBHs) in dwarf galaxies is elusive, but fundamentally important to understand the coevolution of black holes with their hosts and the formation of the first

Unveiling the Population of Wandering Black Holes via Electromagnetic Signatures

While most galaxies appear to host a central supermassive black hole (SMBH), they are expected to also contain a substantial population of off-center “wandering” SMBHs naturally produced by the



Populating the Upper Black Hole Mass Gap through Stellar Collisions in Young Star Clusters

Theoretical modeling of massive stars predicts a gap in the black hole (BH) mass function above ∼40–50 M ⊙ for BHs formed through single star evolution, arising from (pulsational) pair-instability

Formation of massive black holes in rapidly growing pre-galactic gas clouds

A radiation hydrodynamics simulation of early galaxy formation suggests that the dynamics of structure formation, rather than the Lyman–Werner flux, drives the formation of massive black holes in the early Universe.

Jumping the Gap: Searching for LIGO’s Biggest Black Holes

Gravitational wave (GW) detections of binary black holes (BBHs) have shown evidence for a dearth of component black holes with masses above ∼50M ⊙. This is consistent with expectations of a mass gap

GW190521: A Binary Black Hole Merger with a Total Mass of 150  M_{⊙}.

It is inferred that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65  M⊙, which can be considered an intermediate mass black hole (IMBH).
