Primordial Asymmetries, Primordial Equation of State & Primordial Black Holes

Maël Gonin, Julien Froustey, Albert Escrivà +3

We study the thermal history of the primordial Universe in the presence of non-zero lepton and baryon asymmetries. Considering different scenarios, we determine the equation of sta…

The LISA forecast on a smooth crossover beyond the Standard Model through the scalar-induced gravitational waves

Albert Escrivà, Ryoto Inui, Yuichiro Tada +1

Supposing the Laser Interferometer Space Antenna (LISA) gravitational wave (GW) detector, we exhibit the detectability of a hypothetical smooth crossover in the early universe beyo…

Were you born in an aborted primordial black hole?

Emilie Despontin, Sebastien Clesse, Albert Escrivà +1

We propose a mechanism of electroweak baryogenesis based on the Standard Model and explaining the coincidence between the baryon and Dark Matter (DM) densities. Large curvature flu…

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…

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…

Primordial Black Holes

Albert Escrivà, Florian Kuhnel, Yuichiro Tada

Aspects of primordial black holes, i.e. black holes formed in the early Universe, are reviewed. Special emphasis is put on their formation, their role as dark matter candidates and…
