Primordial Black Holes and Induced Gravitational Waves from a Smooth Crossover beyond Standard Model
Albert Escrivà, Yuichiro Tada, Chul-Moon Yoo
Gravitational waves (GWs) induced by primordial fluctuations can be affected by the modification of the sound speed and the equation of state parameter once the c…

Primordial Black Hole formation from overlapping cosmological fluctuations
Albert Escrivà, Chul-Moon Yoo
We consider the formation of primordial black holes (PBHs), during the radiation-dominated Universe, generated from the collapse of super-horizon curvature fluctuations that are ov…

Formation of trapped vacuum bubbles during inflation, and consequences for PBH scenarios
Albert Escrivà, Vicente Atal, Jaume Garriga
A class of inflationary scenarios for primordial black hole (PBH) formation include a small barrier in the slope of the potential. There, the inflaton slows down, generating an enh…
