Detecting the Stochastic Gravitational Wave Background from Primordial Black Holes in Slow-reheating Scenarios
Luis E. Padilla, Juan Carlos Hidalgo, Karim A. Malik +1
After primordial inflation, the universe may have experienced a prolonged reheating epoch, potentially leading to a phase of matter domination supported by the oscillating inflaton…
