Description
We consider pre BBN energy injection via PBH evaporation or Moduli decay into universe and it's possible detection via Gravitational waves via phase transitions in hidden sectors. The energy injection leads to three correlated peaks gravitational wave signatures instead of the usual one peak. The resultant GW amplitude is also stronger than the usual scenario, and hence can be probed via upcoming GW observatories as well, leading to constraints on such early universe energy injections.
