Can QCD Axion Stars explain Subaru HSC microlensing?
Enrico D. Schiappacasse, Tsutomu T. Yanagida
A non-negligible fraction of the QCD axion dark matter may form gravitationally bound Bose Einstein condensates, which are commonly known as axion stars or axion clumps. Such astro…
Microlensing constraints on axion stars including finite lens and source size effects
Kohei Fujikura, Mark P. Hertzberg, Enrico D. Schiappacasse +1
A fraction of light scalar dark matter, especially axions, may organize into Bose-Einstein condensates, gravitationally bound clumps, "boson stars", and be present in large number…
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…
Space and Time Averaged Quantum Stress Tensor Fluctuations
Peter Wu, L. H. Ford, Enrico D. Schiappacasse
We extend previous work on the numerical diagonalization of quantum stress tensor operators in the Minkowski vacuum state, which considered operators averaged in a finite time inte…
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…
