Bubbles kick off primordial black holes to form more binaries
Physical Review ResearchPrimordial black holes (PBHs) may form before cosmological first-order phase transitions, leading to inevitable collisions between PBHs and bubble walls. In this paper, we have simulated the coevolution of an expanding scalar wall passing through a black

Structure of the Baryon Halo Around a Supermassive Primordial Black Hole
ParticlesAccording to some theoretical models, primordial black holes with masses of more than 108 solar masses could be born in the early universe, and their possible observational manifestations have been investigated in a number of works. Dense dark matter and

Large fluctuations and primordial black holes
Physics ReportsIn this paper, we review in detail different mechanisms of generation of large primordial fluctuations and their implications for the production of primordial black holes (PBHs) and scalar-induced secondary gravity waves (SIGW), with the ultimate aim of understanding the impact of loop correction on quantum correlations and the power spectrum.

How open is the asteroid-mass primordial black hole window?
SciPost PhysicsPrimordial black holes (PBHs) can make up all of the dark matter (DM) if their mass, $m$, is in the so-called "asteroid-mass window", $10^{17} g ≲ m ≲ 10^{22} g$. Observational constraints on the abundance of PBHs are usually calculated assuming they all
