Theoretical uncertainties in reconstructing model parameters with gravitational waves from supercooled phase transitions
Maciej Kierkla, Marek Lewicki, Philipp Schicho +2
Future interferometers may detect a gravitational-wave (GW) signal from a cosmological first-order phase transition. Reconstructing the underlying particle-physics model from such…
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…
Memory burden effect mimics reheating signatures on SGWB from ultra-low mass PBH domination
Nilanjandev Bhaumik, Md Riajul Haque, Rajeev Kumar Jain +1
Ultra-low mass primordial black holes (PBH), briefly dominating the expansion of the universe, would leave detectable imprints in the secondary stochastic gravitational wave backgr…
Ultra-low mass PBHs in the early universe can explain the PTA signal
Nilanjandev Bhaumik, Rajeev Kumar Jain, Marek Lewicki
Pulsar Timing Array collaborations have recently announced the discovery of a stochastic gravitational wave background (SGWB) at nanohertz frequencies. We analyze the GW signals fr…
