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 about 10−14 M⊙ to 10−11 M⊙. We study PBHs as the source of fast radio bursts (FRBs) via magnetic reconnection in the event of collisions between them and neutron stars (NSs) in galaxies. We investigate the energy loss of PBHs during PBH-NS encounters to model their capture by NSs. To an order-of-magnitude estimation, we conclude that the parameter space of PBHs being all DM is accidentally consistent with that to produce FRBs with a rate which is the order of the observed FRB rate.

Implications for dark matter direct detection in the presence of LIGO-motivated primordial black holes Hertzberg, Mark P.; Schiappacasse, Enrico D.; Yanagida, Tsutomu T. (Elsevier, 2020)We discuss formation of dark matter (DM) mini-halos around primordial black holes (PBHs) and its implication on DM direct detection experiments, including axion searches. Motivated by LIGO observations, we consider fDM≃0.01 ...

(American Physical Society, 2021)We study the well-motivated mixed dark matter (DM) scenario composed of a dominant thermal WIMP, highlighting the case of SU(2)L triplet fermion “winos,” with a small fraction of primordial black holes (PBHs).

Radio signatures from encounters between neutron stars and QCD-axion minihalos around primordial black holes Nurmi, Sami; Schiappacasse, Enrico D.; Yanagida, Tsutomu T. (IOP Publishing, 2021)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 axion DM via transient radio signatures ...
Hertzberg, Mark P.; Schiappacasse, Enrico D.; Yanagida, Tsutomu T. (American Physical Society, 2020)We consider a general class of axion models, including the QCD and string axion, in which the PQ symmetry is broken before or during inflation. Assuming the axion is the dominant component of the dark matter, we discuss ...
