Primordial black holes (PBHs) might form from the collapse of over-densed regions
generated by large scalar curvature perturbations in the radiation dominated era. Despite …

For a variety of ongoing and planned gravitational-wave (GW) experiments, we study
expected constraints on the fraction (f PBH) of primordial black holes (PBHs) in dark matter …

The detection of binary black hole coalescences by LIGO and Virgo has aroused the interest
in primordial black holes (PBHs), because they could be both the progenitors of these black …

We present a search for subsolar mass ultracompact objects in data obtained during
Advanced LIGO's second observing run. In contrast to a previous search of Advanced LIGO …

In this paper we calculate the scalar induced gravitational waves (SIGWs) accompanying the
formation of primordial black holes during the radiation dominated era in three different …

In the model where Primordial Black Holes (PBHs) form from large primordial curvature (C)
perturbations, ie, CPBHs, constraints on PBH abundance provide in principle constraints on …

As one of the promising candidates of cold dark matter, primordial black holes (PBHs) were
formed due to the collapse of overdense regions generated by the enhanced curvature …

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 …

We report on a search for compact binary coalescences where at least one binary
component has a mass between 0.2 M⊙ and 1.0 M⊙ in Advanced LIGO and Advanced …

We recently showed that postulated ultracompact minihalos with a steep density profile do
not form in realistic simulations with enhanced initial perturbations. In this paper we assume …
