Can Primordial Black Holes as all Dark Matter explain Fast Radio Bursts?
Kimmo Kainulainen, Sami Nurmi, Enrico D. Schiappacasse +1
Primordial black holes (PBHs) are one of the most interesting nonparticle dark matter (DM) candidates. They may explain all the DM content in the Universe in the mass regime from a…
Higgs-like spectator field as the origin of structure
Alexandros Karam, Tommi Markkanen, Luca Marzola +3
We show that the observed primordial perturbations can be entirely sourced by a light spectator scalar field with a quartic potential, akin to the Higgs boson, provided that the fi…
Radio signatures from encounters between Neutron Stars and QCD-Axion Minihalos around Primordial Black Holes
Sami Nurmi, Enrico D. Schiappacasse, Tsutomu T. Yanagida
Probing the QCD axion dark matter (DM) hypothesis is extremely challenging as the axion interacts very weakly with Standard Model particles. We propose a new avenue to test the QCD…
