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…
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…
Non-thermal Dark Matter in Extension of Inert Doublet Model
Maien Binjonaid, Ahmed Elsheshtawy, Shaaban Khalil
We propose an extension of the Inert Doublet Model (IDM) that explains both neutrino masses and dark matter (DM) in the intermediate-mass range by incorporating a gaug…
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…
