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…

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…

Gravitational wave signals from primordial black holes orbiting solar-type stars

Vitorio A. De Lorenci, David I. Kaiser, Patrick Peter +2

Primordial black holes (PBHs) with masses between and kg are candidates to contribute a substantial fraction of the total dark matter abundance. When in orbit a…

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…

Orbital motion of primordial black holes crossing Solar-type stars

Vitorio A. De Lorenci, David I. Kaiser, Patrick Peter

Primordial black holes (PBHs) are hypothetical objects that could have originated from density fluctuations in a very early phase of our Universe. Recent observations restrict the…

Close encounters of the primordial kind: a new observable for primordial black holes as dark matter

Tung X. Tran, Sarah R. Geller, Benjamin V. Lehmann +1

Primordial black holes (PBHs) remain a viable dark matter candidate in the asteroid-mass range. We point out that in this scenario, the PBH abundance would be large enough for at l…
