Primordial Black Hole Sterile Neutrinogenesis: Sterile Neutrino Dark Matter Production Independent of Couplings
Muping Chen, Graciela B. Gelmini, Philip Lu +1
Sterile neutrinos (s) are well-motivated and actively searched for hypothetical neutral particles that would mix with the Standard Model active neutrinos. They are considered…
Primordial Black Hole Neutrinogenesis of Sterile Neutrino Dark Matter
Muping Chen, Graciela B. Gelmini, Philip Lu +1
Sterile neutrinos are well-motivated and actively searched for new particles that would mix with the active neutrinos. We study their phenomenology when they are produced in the ev…
Catastrogenesis with unstable ALPs as the origin of the NANOGrav 15 yr gravitational wave signal
Graciela B. Gelmini, Jonah Hyman
In post-inflation axion-like particle (ALP) models, a stable domain wall network forms if the model's potential has multiple minima. This system must annihilate before dominating t…
Primordial black hole dark matter from catastrogenesis with unstable pseudo-Goldstone bosons
Graciela B. Gelmini, Jonah Hyman, Anna Simpson +1
We propose a new scenario for the formation of asteroid-mass primordial black holes (PBHs). Our mechanism is based on the annihilation of the string-wall network associated with th…
