Gravitational Waves and Cosmological Observables from First-Order Phase Transitions: Thermal Corrections at Low Temperature
Katharena Christy, James B. Dent, Sumit Ghosh +2
We consider the impact on cosmological first-order phase transitions (FOPTs) of low-temperature thermal corrections to the effective potential. These are corrections from degrees o…

Primordial black holes from Q-balls produced in a first-order phase transition
James B. Dent, Bhaskar Dutta, Jason Kumar +1
We consider the formation of Q-balls in false vacuum remnants during a cosmological first-order phase transition. We find that under certain circumstances Q-balls can collapse to f…
