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 Are True Vacuum Nurseries
Louis Hamaide, Lucien Heurtier, Shi-Qian Hu +1
The Hawking evaporation of primordial black holes (PBH) reheats the Universe locally, forming hot spots that survive throughout their lifetime. We propose to use the temperature pr…
Hunting for Neutral Leptons with Ultra-High-Energy Cosmic Rays
Robert Heighton, Lucien Heurtier, Michael Spannowsky
Next-generation large-volume detectors, such as GRAND, POEMMA, Trinity, TAROGE-M, TAMBO, or PUEO, have been designed to search for ultra-high-energy cosmic rays (UHECRs) with unpre…
Primordial Black Hole Archaeology with Gravitational Waves from Cosmic Strings
Anish Ghoshal, Yann Gouttenoire, Lucien Heurtier +1
Light primordial black holes (PBHs) with masses smaller than g () evaporate before the onset of Big-Bang nucleosynthesis, rendering their detection rather…
Evaporation of Primordial Black Holes in the Early Universe: Mass and Spin Distributions
Andrew Cheek, Lucien Heurtier, Yuber F. Perez-Gonzalez +1
Many cosmological phenomena lead to the production of primordial black holes in the early Universe. These phenomena often create a population of black holes with extended mass and…
Signatures of Non-thermal Dark Matter with Kination and Early Matter Domination: Gravitational Waves versus Laboratory Searches
Anish Ghoshal, Lucien Heurtier, Arnab Paul
The non-thermal production of dark matter (DM) usually requires very tiny couplings of the dark sector with the visible sector and therefore is notoriously challenging to hunt in l…
