Primordial Black Holes and their Mass Spectra: The Effects of Mergers and Accretion within Stasis Cosmologies
Keith R. Dienes, Lucien Heurtier, Fei Huang +2
A variety of processes in the very early universe can give rise to a population of primordial black holes (PBHs) with an extended mass spectrum. For certain mass spectra of this so…
Non-linear Dynamics and Primordial Black Hole Formation During Kination
Cheng Cheng, Panagiotis Giannadakis, Lucien Heurtier +1
We investigate the effects of large scalar inhomogeneities during the kination epoch, a period in which the universe's dynamics are dominated by the kinetic energy of a scalar fiel…
Spotting Stasis in Cosmological Perturbations
Keith R. Dienes, Lucien Heurtier, Daniel Hoover +3
As discussed in a number of recent papers, cosmological stasis is a phenomenon wherein the abundances of multiple cosmological energy components with different equations of state r…
Primordial Black Hole Hot Spots and Nucleosynthesis
Clelia Altomonte, Malcolm Fairbairn, Lucien Heurtier
Upon their evaporation via Hawking radiation, primordial black holes (PBHs) may deposit energy in the ambient plasma on scales smaller than the typical distance between two black h…
Primordial Black Hole Hot Spots and Out-of-Equilibrium Dynamics
Jacob Gunn, Lucien Heurtier, Yuber F. Perez-Gonzalez +1
When light primordial black holes (PBHs) evaporate in the early Universe, they locally reheat the surrounding plasma, creating hot spots with temperatures that can be significantly…
Primordial black holes from an interrupted phase transition
Wen-Yuan Ai, Lucien Heurtier, Tae Hyun Jung
We propose a new mechanism of primordial black hole formation via an interrupted phase transition during the early matter-dominated stage of reheating after inflation. In reheating…
