We update the constraints on the fraction of the Universe that may have gone into primordial
black holes (PBHs) over the mass range 10− 5 to 10 50 g. Those smaller than∼ 10 15 g …

The detection of gravitational waves from mergers of tens of Solar mass black hole binaries
has led to a surge in interest in primordial black holes (PBHs) as a dark matter candidate …

The LIGO/Virgo collaboration have by now detected the mergers of ten black hole binaries
via the emission of gravitational radiation. The hypothesis that these black holes have …

Primordial black holes (PBHs), formed out of large overdensities in the early Universe, are a
viable dark matter (DM) candidate over a broad range of masses. Ultralight, asteroid-mass …

We analytically calculate the scalar induced gravitational waves (SIGWs) and find a log-
dependent slope of SIGW in the infrared regions (f< fc), namely n GW (f)= 3-2/ln (fc/f), and n …

Primordial Black Holes (PBH) can form in the early universe and might comprise a
significant fraction of the dark matter. Interestingly, they are accompanied by the generation …

We present the first search for gravitational waves from the coalescence of stellar mass and
subsolar mass black holes with masses between 20–100 M⊙ and 0.01–1 M⊙(10–10 3 MJ) …

We investigate the correlation between the distribution of galaxies and the predicted
gravitational-wave background of astrophysical origin. We show that the large angular scale …

Primordial black holes possibly formed in the early Universe could provide a significant
fraction of the dark matter and would be unique probes of inflation. A smoking gun for their …

Black holes binaries coming from a distribution of primordial black holes might exhibit a
large merger rate up to large redshifts. Using a phenomenological model for the merger rate …
