Enlightening dark moments of neutrino with superradiance
Indra Kumar Banerjee, Ujjal Kumar Dey, Anna John
Neutrinos can acquire electromagnetic moments either within the Standard Model through higher order radiative corrections or within the domain of new physics. In this study we focu…
Primordial Black Holes from Slow Phase Transitions with Delayed Reheating: A Peak-Theory Approach
Indra Kumar Banerjee
We study the possibility of significant PBH production from a slow first-order phase transition with delayed reheating. Since delayed reheating results in an early matter-dominated…
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. However, spin varia…
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…
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…
Neutrino Decoherence via Modified Dispersion
Bikash Kumar Acharya, Indra Kumar Banerjee, Ujjal Kumar Dey
We study in detail the effect of quantum decoherence in neutrino oscillations. We adopt a phenomenological approach that allows us to parametrize the energy dependence of the decoh…
Primordial Black Holes (as Dark Matter) from the Supercooled Phase Transitions with Radiative Symmetry Breaking
Indra Kumar Banerjee, Francesco Rescigno, Alberto Salvio
We study in detail the production of primordial black holes (PBHs), as well as their mass and initial spin, due to the phase transitions corresponding to radiative symmetry breakin…
Spin of Primordial Black Holes from Broad Power Spectrum: Radiation Dominated Universe
Indra Kumar Banerjee, Tomohiro Harada
We perform a study to obtain the initial spin or the nondimensional Kerr parameter of primordial black holes (PBHs) created during the radiation dominated phase of the univ…
Multi-messenger Astronomy with Quenched Superradiance
Indra Kumar Banerjee, Soumya Bonthu, Ujjal Kumar Dey
We propose a novel method to study the ultra-light bosons, where compact rotating objects undergo the phenomenon of quenched superradiance to create gravitational waves and neutrin…
Primordial Black Holes and Gravitational Waves in the Extended Inert Doublet Model: A First-Order Phase Transition Perspective
Indra Kumar Banerjee, Ujjal Kumar Dey, Shaaban Khalil
We conduct an analysis of a extended inert doublet model and obtained the parameter space allowing strong first order phase transitions. We show that a large part of t…
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…

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…
