Baryogenesis from Exploding Primordial Black Holes
Alexandra P. Klipfel, Miguel Vanvlasselaer, Sokratis Trifinopoulos +1
Exploding primordial black holes can source baryon asymmetry soon after the electroweak phase transition, as high-energy Hawking radiation drives ultrarelativistic shocks in the su…
Shocks from Exploding Primordial Black Holes in the Early Universe
Miguel Vanvlasselaer, Sokratis Trifinopoulos, Alexandra P. Klipfel +1
We investigate how Hawking radiation from low-mass primordial black holes deposits energy into the early-universe plasma and show that the resulting phenomena are hydrodynamic rath…
Primordial Black Holes from Inflation with a Spectator Field
Dario L. Lorenzoni, Sarah R. Geller, David I. Kaiser +1
How is the production of primordial black holes (PBHs) in single-field models of inflation impacted by the presence of additional scalar fields? We consider the effect of a spectat…
Light Scalar Fields Foster Production of Primordial Black Holes
Dario L. Lorenzoni, Sarah R. Geller, Zachary Ireland +3
Scalar fields are ubiquitous in theories of high-energy physics. In the context of cosmic inflation, this suggests the existence of spectator fields, which provide a subdominant so…
