Axion Star Nucleation in Dark Minihalos around Primordial Black Holes
Mark P. Hertzberg, Enrico D. Schiappacasse, Tsutomu T. Yanagida
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 c…
Implications for Dark Matter Direct Detection in the Presence of LIGO-Motivated Primordial Black Holes
Mark P. Hertzberg, Enrico D. Schiappacasse, Tsutomu T. Yanagida
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…
Probing Dynamics of Boson Stars by Fast Radio Bursts and Gravitational Wave Detection
Gongjun Choi, Hong-Jian He, Enrico D. Schiappacasse
Boson stars may consist of a new type of light singlet scalar particles with nontrivial self-interactions, and may compose a fraction of the dark matter in the Universe. In this wo…
