Imprints of Reheating Dynamics on Gravitational Waves from Phase Transitions
Basabendu Barman, Maciej Kierkla, Marek Lewicki +1
We investigate how perturbative reheating after inflation modifies the primordial gravitational wave (GW) spectrum generated by cosmological phase transitions. Within a specific in…
Probing Reheating with Gravitational Waves from Graviton Bremsstrahlung
Basabendu Barman, Nicolás Bernal, Simon Cléry +3
In this talk, based on arXiv:2301.11345, arXiv:2305.16388, arXiv:2311.12694, we discuss the production of primordial gravitational waves (GW) sourced by graviton bremsstrahlung dur…
Gravitational wave signatures of cogenesis from a burdened PBH
Basabendu Barman, Md Riajul Haque, Óscar Zapata
We explore the possibility of explaining the observed dark matter (DM) relic abundance, along with matter-antimatter asymmetry, entirely from the evaporation of primordial black ho…
Implications of NANOGrav results and UV freeze-in in a fast-expanding Universe
Basabendu Barman, Amit Dutta Banik, Avik Paul
Recent pulsar timing data reported by the NANOGrav collaboration indicates the existence of a stochastic gravitational wave (GW) background at a frequency . W…
