Spinning Primordial Black Holes from First Order Phase Transition
Indra Kumar Banerjee, Ujjal Kumar Dey
We conduct a novel study to obtain the initial spin of the primordial black holes created during a first-order phase transition due to delayed false vacuum decay. Remaining within…
Gravitational Wave Probe of Primordial Black Hole Origin via Superradiance
Indra Kumar Banerjee, Ujjal Kumar Dey
In this article we have used stochastic gravitational wave background as a unique probe to gain insight regarding the creation mechanism of primordial black holes. We have consider…
Probing the Origin of Primordial Black Holes through Novel Gravitational Wave Spectrum
Indra Kumar Banerjee, Ujjal Kumar Dey
In this article we investigate the cumulative stochastic gravitational wave spectra as a tool to gain insight on the creation mechanism of primordial black holes. We consider gravi…
PTOLEMY's test of generalized neutrino interactions: unveiling challenges and constraints
Indra Kumar Banerjee, Ujjal Kumar Dey, Newton Nath +1
Unanswered questions surrounding neutrinos have motivated investigations into physics beyond the standard model (SM) of particle physics. In particular, generalized neutrino intera…
A hidden gauged addressing radiative neutrino mass, dark matter, , and tension
Ujjal Kumar Dey, Hiroshi Okada
We propose a radiative seesaw model with a hidden gauge symmetry. In order to have anomaly cancellations, we need to introduce several new fermions that contribute to muon a…
