Accounting for the minimal mass spread of primordial black holes from gravitational collapse suppresses the Poltergeist GW background to the level of generic scalar-induced signals and reopens ultra-light PBH parameter space.
Computes the dimensionless spin parameter s = J/(G_N M^2) of false vacuum bubbles from density and velocity perturbations in FOPTs, yielding values from O(10^{-5}) to O(10) and a scaling relation with FOPT timescale, wall velocity, and temperature ratio.
Dynamical LTE simulations reveal that heating wave formation often outlasts wall acceleration, yielding a revised maximal driving pressure criterion that weakens hydrodynamic obstruction compared to steady-state models.
Hotspots around light primordial black holes cool faster in an expanding universe following T_plt ∝ t^{-11/15} and vanish completely in finite time, unlike everlasting hotspots in flat spacetime.
Generalization of scalar-fermion Yukawa systems in constant-EOS cosmologies identifies scaling regime with constant energy density ratio from approximate scale invariance and asymptotic regime recovering bare mass.
PBH production from slow phase transitions with delayed reheating is modeled via peak theory and Monte Carlo simulations, showing extreme sensitivity to reheating efficiency and potential to explain all dark matter.
Dark sector first-order phase transitions near 10 MeV can substantially modify vector dark matter relic densities away from standard thermal freeze-out predictions, with distinct mass windows and calculable gravitational wave backgrounds.
Regular primordial black holes can evaporate completely like singular ones and yield the observed dark matter density under modified cosmological constraints.
PBH-triggered SN Ia models across metallicities match some observed light curves and remnants, constrain the explosion channel fraction via chemical evolution modeling, and indicate PBHs as a potentially major early-universe SN Ia source.
