Acoustically driven dark matter freeze-out

Iason Baldes, Ryusuke Jinno

We extend the study of the effect of density perturbations to the well known thermal dark matter freeze-out scenario. We find enhancements in the cross section are…

Leptogenesis with perturbations in type-II and type-III seesaw models

Iason Baldes

Density perturbations have recently been shown to lead to a novel effect in the freeze-out of heavy particles called "acoustically driven freeze-out." This leads to an enhancement…

Particle shells from relativistic bubble walls

Iason Baldes, Maximilian Dichtl, Yann Gouttenoire +1

Relativistic bubble walls from cosmological phase transitions (PT) necessarily accumulate expanding shells of particles. We systematically characterize shell properties, and identi…

Primordial black holes as dark matter: Interferometric tests of phase transition origin

Iason Baldes, María Olalla Olea-Romacho

We show that primordial black holes - in the observationally allowed mass window with - formed from late nucleating patches in a first order phase transition imply…

Bubbletrons: Ultrahigh-Energy Particle Collisions and Heavy Dark Matter at Phase Transitions

Iason Baldes, Maximilian Dichtl, Yann Gouttenoire +1

We initiate the study of `bubbletrons', by which we mean ultra-high-energy collisions of the particle shells that generically form at the walls of relativistic bubbles in cosmologi…

Hot and heavy dark matter from a weak scale phase transition

Iason Baldes, Yann Gouttenoire, Filippo Sala

We point out that dark matter which is produced non-adiabatically in a phase transition (PT) with fast bubble walls receives a boost in velocity which leads to long free-streaming…
