Primordial black holes from a cosmic phase transition: The collapse of Fermi-balls

TL;DR: In this paper, a new mechanism of primordial black hole (PBH) production during first-order phase transitions (PTs) was proposed and the predicted mass function of PBHs was nearly monochromatic.

TL;DR: Review of steps from particle physics model to gravitational wave phenomenology for first-order phase transitions in the early Universe.

TL;DR: In this article , it was shown that radiated bosons are dominantly soft and that the resulting retarding pressure on relativistic bubble walls is linear both in the Lorentz boost and in the order parameter up to a log.

TL;DR: In this article , a primordial black hole (PBH) was formed by the collapse of non-topological solitons called Fermi-balls, which form via trapping fermions in the false vacuum during the first-order electroweak phase transition (FOEWPT).

TL;DR: In this article, it was shown that any black hole will create and emit particles such as neutrinos or photons at just the rate that one would expect if the black hole was a body with a temperature of (κ/2π) (ħ/2k) ≈ 10−6 (M/M)K where κ is the surface gravity of the body.

TL;DR: This second gravitational-wave observation provides improved constraints on stellar populations and on deviations from general relativity.

TL;DR: In this paper, a first-order QCD phase transition that occurred reversibly in the early universe would lead to a surprisingly rich cosmological scenario, which is at least conceivable that the phase transition would concentrate most of the quark excess in dense, invisible quark nuggets, providing an explanation for the dark matter in terms of QCD effects only.

TL;DR: The magnitude of modifications to the gravitational-wave dispersion relation is constrain, the graviton mass is bound to m_{g}≤7.7×10^{-23} eV/c^{2} and null tests of general relativity are performed, finding that GW170104 is consistent with general relativity.
