Understanding How Fast Black Holes Spin by Analyzing Data from the Second Gravitational-wave Catalogue
The Advanced LIGO and Virgo detectors have now observed approximately 50 black hole binary mergers, from which we can begin to infer how rapidly astrophysical black holes spin. The LIGO-Virgo
Spin of primordial black holes in the model with collapsing domain walls
The angular momentum (spin) acquisition by a collapsing domain wall at the cosmological radiation-dominated stage is investigated. During the collapses, primordial black holes and their clusters can
State of the Field: Binary Black Hole Natal Kicks and Prospects for Isolated Field Formation after GWTC-2
Advanced LIGO and Advanced Virgo’s newly released GWTC-2 catalog of gravitational-wave detections offers unprecedented information about the spin magnitudes and orientations of merging binary black
Signatures of primordial black hole dark matter at DUNE and THEIA
Primordial black holes (PBHs) are a potential dark matter candidate whose masses can span over many orders of magnitude. If they have masses in the 1015–1017 g range, they can emit sizeable fluxes of
21-cm constraints on spinning primordial black holes
Hawking radiation from primordial black holes (PBH) can ionize and heat up neutral gas during the cosmic dark ages, leaving imprints on the global 21-cm signal of neutral hydrogen. We use the global
Snowmass2021 Cosmic Frontier White Paper:Primordial Black Hole Dark Matter
Primordial Black Holes (PBHs) are a viable candidate to comprise some or all of the dark matter and provide a unique window into the high-energy physics of the early universe. This white paper
BlackHawk: a public code for calculating the Hawking evaporation spectra of any black hole distribution
We describe BlackHawk, a public C program for calculating the Hawking evaporation spectra of any black hole distribution. This program enables the users to compute the primary and secondary spectra

Density perturbations and black hole formation in hybrid inflation.
TLDR
It is shown that density perturbations in hybrid inflation models of the new type can be very large on the scale corresponding to the phase transition, which could lead to a copious production of black holes in these models.
Properties and Astrophysical Implications of the 150 M⊙ Binary Black Hole Merger GW190521
The gravitational-wave signal GW190521 is consistent with a binary black hole (BBH) merger source at redshift 0.8 with unusually high component masses, 85 − 14 + 21 M⊙ and 66 − 18 + 17 M⊙, compared
Induced spins from scattering experiments of initially nonspinning black holes
When two relativistically boosted, nonspinning black holes pass by one another on a scattering trajectory, we might expect the tidal interaction to spin up each black hole. We present the first
Mind the Gap: The Location of the Lower Edge of the Pair-instability Supernova Black Hole Mass Gap
Detections of gravitational waves are now starting to probe the mass distribution of stellar mass black holes (BHs). Robust predictions from stellar models are needed to interpret these. Theory
GW190425, GW190521 and GW190814: Three candidate mergers of primordial black holes from the QCD epoch
The two recent gravitational-wave events GW190425 and GW190814 from the third observing run of LIGO/Virgo have both a companion which is unexpected if originated from a neutron star or a stellar
Gravitational waves from spinning compact binaries in hyperbolic orbits
Compact binaries in hyperbolic orbits are plausible gravitational wave (GW) sources for the upcoming and planned GW observatories. We develop an efficient prescription to compute post-Newtonian (PN)
