Electromagnetic Signatures From Primordial Black Holes in the Solar System
Alexandra P. Klipfel, David I. Kaiser
Primordial black holes (PBHs) in the asteroid-mass range, with typical masses , have drawn significant recent attention as a v…
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…
Gravitational Ionization by Schwarzschild Primordial Black Holes
Alexandra P. Klipfel, David I. Kaiser
Primordial black holes (PBHs) are theorized to form from the collapse of overdensities in the very early Universe. PBHs in the asteroid-mass range $10^{17} \, {\rm g}\lesssim M \le…
Hawking Radiation Signatures from Primordial Black Holes Transiting the Inner Solar System: Prospects for Detection
Alexandra P. Klipfel, Peter Fisher, David I. Kaiser
Primordial black holes (PBHs) arise from the collapse of density perturbations in the early universe and serve as a dark matter (DM) candidate and a probe of fundamental physics. T…
Ultra-High-Energy Neutrinos from Primordial Black Holes
Alexandra P. Klipfel, David I. Kaiser
The KM3NeT Collaboration recently announced the detection of a neutrino with energy 220 PeV. One possible source of such ultra-high-energy particles is the rapid emission of energe…
