Gravitational Wave Production During Reheating: From the Inflaton to Primordial Black Holes
Mathieu Gross, Essodjolo Kpatcha, Yann Mambrini +2
We calculate the gravitational waves (GWs) produced by primordial black holes (PBHs) in the presence of the inflaton condensate in the early Universe. Combining the GW production f…

Relic neutrino decay: a solution to the excess radio background
Rishav Roshan
The detection of excess radio background detected by ARCADE 2 suggests the presence of new physics as there exists no clear astrophysical solution. We find that the radiative decay…

Quantum Gravity Effects on Dark Matter and Gravitational Waves
Stephen F. King, Rishav Roshan, Xin Wang +2
We explore how quantum gravity effects, manifested through the breaking of discrete symmetry responsible for both Dark Matter and Domain Walls, can have observational effects throu…
