Impact of Primordial Black Holes Induced Neutrinos on the Cosmic 21-cm Brightness Temperature
Prabhav Singh, Mansi Dhuria, Gaurav Goswami
We study the impact of neutrinos emitted from evaporating Primordial Black Holes (PBHs) on the global 21-cm absorption signal during the dark ages and pre-reionization epochs. PBHs…

KM3-230213A and IceCube Neutrino Events from Metastable Dark Matter of Primordial Black Hole Origin
Prabhav Singh, Mansi Dhuria, Nathanael Varghese Job
We investigate a scenario in which the recently observed ultra-high-energy neutrino event KM3-230213A, with a median energy of approximately 220 PeV, as well as the high-energy neu…

Probing self-interacting ultrahigh-energy neutrinos with the cosmic 21-cm signal
Mansi Dhuria, Bishnu Gupta Teli
In this study, we investigate the constraints on secret self-interactions of neutrinos by examining the impact of radiative scattering of ultrahigh-energy neutrinos. These neutrino…
