New calculation of collision integrals for cosmological phase transitions
Carlo Branchina, Angela Conaci, Stefania De Curtis +4
First order phase transitions in the early universe may have left a variety of experimentally accessible imprints. The dynamics of such transitions is governed by the density pertu…
Axion Dark Matter from Heavy Quarks
Mohammad Aghaie, Giovanni Armando, Angela Conaci +5
We propose simple scenarios where the observed dark matter abundance arises from decays and scatterings of heavy quarks through freeze-in of an axion-like particle with mass in the…
Slaying Axion-Like Particles via Gravitational Waves and Primordial Black Holes from Supercooled Phase Transition
Angela Conaci, Luigi Delle Rose, P. S. Bhupal Dev +1
We study the formation of primordial black holes (PBHs) from density fluctuations due to supercooled phase transitions (PTs) triggered in an axion-like particle (ALP) model. We fin…
