Primordial Magnetogenesis and Gravitational Waves from ALP-assisted Phase Transition
Pankaj Borah, P. S. Bhupal Dev, Anish Ghoshal
Sufficiently strong first-order phase transitions (FOPTs) in the early Universe can simultaneously produce an observable stochastic gravitational wave background (SGWB) and a large…

Unveiling the inert Triplet desert region with a pNGB Dark Matter and its Gravitational Wave signatures
Pankaj Borah, Pradipta Ghosh
In this work, we extend the scalar sector of the conventional hyperchargeless inert triplet model (ITM) to include a second dark matter (DM) candidate, which appears to be a pseudo…

Prospecting bipartite Dark Matter through Gravitational Waves
Pankaj Borah, Pradipta Ghosh, Abhijit Kumar Saha
We explore the gravitational wave probes of a two-component dark matter framework, consisting of an triplet scalar and a Standard Model singlet fermion. The triplet scala…
