Mini-review on the production of Primordial Black Holes from First-Order Phase Transitions in the Early Universe
Indra Kumar Banerjee, Ujjal Kumar Dey, Shaaban Khalil
We review the creation mechanism of primordial black holes from first order phase transitions. We discuss various model-dependent and independent mechanisms and relate the properti…
Radiative symmetry breaking in a gauged Zee-Babu model and its gravitational wave imprints
Indra Kumar Banerjee, Nabarun Chakrabarty, Ujjal Kumar Dey
We construct a classically scale invariant version of the Zee-Babu model governed by an gauge symmetry wherein three right handed neutrinos with identical gauge charge…
Superradiant and dynamical spin-down of neutron stars with gravitational wave implications
Indra Kumar Banerjee, Sandeep Chatterjee, Biswarup Das +1
Neutron stars such as pulsars and magnetars lose angular momentum primarily through electromagnetic dipole radiation, gravitational waves, -mode oscillation, and also affected b…
Bounds on Exotic Couplings from a New -Background
Indra Kumar Banerjee, Ujjal Kumar Dey, Anna John
We propose a hitherto unexplored neutrino background emerging from the mechanism of quenched superradiance of rotating primordial black holes. The quenching of the phenomenon happe…
Asymmetric Cannibal Dark Matter: Constraints from Neutron Star
Ujjal Kumar Dey, Sourav Gope
Asymmetric dark matter can be efficiently captured by neutron stars via elastic scattering with nucleons and dark matter self scattering. The accumulated dark matter thermalizes an…
Primordial Black Holes and Gravitational Waves in Extensions of the Standard Model
Indra Kumar Banerjee, Ujjal Kumar Dey, Shaaban Khalil
We investigate the phenomenology of a Standard Model extension incorporating an inert scalar doublet and a gauged symmetry. Our analysis reveals regions of the paramet…
