The swallowed spike: the formation of light primordial black hole structures around heavy seeds
Agnese Tolino, Francesca Scarcella, Bradley J. Kavanagh +2
Spikes are steep enhancements in the dark matter (DM) distribution around a heavy compact object. If the compact object is primordial, and the bulk of the DM is also composed of (l…

Primordial black hole probes of heavy neutral leptons
Valentina De Romeri, Yuber F. Perez-Gonzalez, Agnese Tolino
Primordial black holes (PBH), while still constituting a viable dark matter component, are expected to evaporate through Hawking radiation. Assuming the semi-classical approximatio…
