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…
Shining Primordial Black Holes
Mark P. Hertzberg, Sami Nurmi, Enrico D. Schiappacasse +1
We study the well-motivated mixed dark matter (DM) scenario composed of a dominant thermal WIMP, highlighting the case of triplet fermion "winos", with a small fraction o…
Merger of Dark Matter Axion Clumps and Resonant Photon Emission
Mark P. Hertzberg, Yao Li, Enrico D. Schiappacasse
A portion of light scalar dark matter, especially axions, may organize into gravitationally bound clumps (stars) and be present in large number in the galaxy today. It is therefore…
Dark Matter Axion Clump Resonance of Photons
Mark P. Hertzberg, Enrico D. Schiappacasse
Recently there has been interest in the physical properties of dark matter axion condensates. Due to gravitational attraction and self-interactions, they can organize into spatial…
Scalar Dark Matter Clumps with Angular Momentum
Mark P. Hertzberg, Enrico D. Schiappacasse
The behavior of light scalar dark matter has been a subject of much interest recently as it can lead to interesting small scale behavior. In particular, this can lead to the format…
