Interstellar Gas Heating by Primordial Black Holes
Kohei Hayashi,Volodymyr Takhistov,Philip Lu,Philip Lu,Sylvia Gottschalk,Graciela B. Gelmini,Kohei Hayashi,Melisa Melisa,Yoshiyuki Inoue,Alexander Kusenko +9 more
TL;DR: The authors constrain the abundance of primordial black holes (PBHs) over a broad mass-range, which is relevant for the recently detected gravitational wave signals from intermediate-mass BHs.
Journal ArticleDOI
Constraining Primordial Black Holes with Dwarf Galaxy Heating
Philip Lu,Volodymyr Takhistov,Graciela B. Gelmini,Kohei Hayashi,Yoshiyuki Inoue,Alexander Kusenko +5 more
TL;DR: In this article, a new limit on the abundance of primordial black holes (PBHs) was established by considering interactions of PBHs with the interstellar medium, which result in the heating of gas.
Journal ArticleDOI
Generalized Halo Independent Comparison of Direct Dark Matter Detection Data
TL;DR: In this article, the authors extend the halo-independent method to compare direct dark matter detection data, so far used only for spin-independent WIMP-nucleon interactions, to any type of interaction.
Journal ArticleDOI
Catastrogenesis: DM, GWs, and PBHs from ALP string-wall networks
TL;DR: In this article , it was shown that, under the generic assumption that the potential has several degenerate minima, GWs from string-wall annihilation at temperatures below 100 eV could be detected by future CMB and astrometry probes, for ALPs with mass from 10-16 to 106 eV.
Journal ArticleDOI
The Perils of a 17 KeV Neutrino
TL;DR: In this article, the authors examined a large body of constraints arising from astrophysics, cosmology, nuclear physics and elementary particle physics on the existence of a 17 KeV neutrino and concluded that such a particle is unlikely.
