Testing Rotating Regular Metrics as Candidates for Astrophysical Black Holes [PDF]
Astrophysical Journal, 2020 The Event Horizon Telescope, a global submillimeter wavelength very long baseline interferometry array, produced the first image of supermassive black hole M87* showing a ring of diameter θd = 42 ± 3 μas, inferred a black hole mass of M = (6.5 ± 0.7 ...

Physical Models for the Astrophysical Population of Black Holes: Application to the Bump in the Mass Distribution of Gravitational-wave Sources [PDF]
Astrophysical Journal, 2023 Gravitational-wave observations of binary black holes have revealed unexpected structure in the black hole mass distribution. Previous studies employ physically motivated phenomenological models and infer the parameters that control the features of the ...

Bayesian evidence for both astrophysical and primordial black holes: mapping the GWTC-2 catalog to third-generation detectors [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We perform a hierarchical Bayesian analysis of the GWTC-2 catalog to investigate the mixed scenario in which the merger events are explained by black holes of both astrophysical and primordial origin.

Can we distinguish astrophysical from primordial black holes via the stochastic gravitational wave background? [PDF]
Monthly notices of the Royal Astronomical Society, 2021 One of the crucial windows for distinguishing astrophysical black holes from primordial black holes is through the redshift evolution of their respective merger rates.

Constraints on the Cosmological Coupling of Black Holes from the Globular Cluster NGC 3201
The Astrophysical Journal Letters, 2023 Globular clusters are among the oldest stellar populations in the Milky Way; consequently, they also host some of the oldest known stellar-mass black holes, providing insight into black hole formation and evolution in the early ( z ≳ 2) universe.

Growth of a Massive Black Hole in a Dense Star Cluster Via Tidal Disruption Accretion
The Astrophysical Journal, 2023 Stars that are tidally disrupted by a massive black hole (MBH) may contribute significantly to the growth of the MBH, especially in dense nuclear star clusters.

Distinguishing primordial black holes from astrophysical black holes by Einstein Telescope and Cosmic Explorer [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 We investigate how the next generation gravitational-wave (GW) detectors, such as Einstein Telescope (ET) and Cosmic Explorer (CE), can be used to distinguish primordial black holes (PBHs) from astrophysical black holes (ABHs).

Astrophysical Black Holes: A Review [PDF]
Proceedings of Multifrequency Behaviour of High Energy Cosmic Sources - XIII — PoS(MULTIF2019), 2019 In this review, I have tried to focus on the development of the field, from the first speculations to the current lines of research. According to Einstein's theory of general relativity, black holes are relatively simple objects and completely ...

Radio Emission From a z = 10.1 Black Hole in UHZ1
The Astrophysical Journal, 2023 The recent discovery of a 4 × 10 ^7 M _⊙ black hole (BH) in UHZ1 at z = 10.3, just 450 Myr after the Big Bang, suggests that the seeds of the first quasars may have been direct-collapse BHs from the collapse of supermassive primordial stars at z ∼ 20 ...

Astrophysical Black Holes: A Compact Pedagogical Review [PDF]
, 2017 Black holes are among the most extreme objects that can be found in the Universe and an ideal laboratory for testing fundamental physics. Here, the basic properties of black holes as expected from general relativity, the main astronomical observations ...
