Primordial Gravitational Waves from Phase Transitions during Reheating
Amitayus Banik, Nicolás Bernal, Fazlollah Hajkarim
We study primordial gravitational waves (GWs) generated from first-order phase transitions (PTs) during cosmic reheating. Using a minimal particle physics model, and a general para…
Two or three things particle physicists (mis)understand about (pre)heating
Basabendu Barman, Nicolás Bernal, Javier Rubio
The transition from the end of inflation to a hot, thermal Universe, commonly referred to as (re)heating, is a critical yet often misunderstood phase in early Universe cosmology. T…
Pre-thermalized Gravitational Waves
Nicolás Bernal, Quan-feng Wu, Xun-Jie Xu +1
We investigate a novel gravitational wave (GW) production mechanism from gravitons generated during the pre-thermal phase of cosmic reheating, where the energy density is dominated…
