DESCRIPTION:We calculate the gravitational waves (GWs) produced by primord
 ial black holes (PBHs) in the presence of the inflaton condensate in the e
 arly Universe. Combining the GW production from the evaporation process\, 
 the gravitational scattering of the inflaton itself\, and the density fluc
 tuations due to the inhomogeneous distribution of PBHs\, we propose for th
 e first time a complete\, coherent analysis of the spectrum\, revealing th
 ree peaks\, one for each source. Three frequency ranges (~kHz\, GHz\, and 
 PHz\, respectively) are expected\, each giving rise to a similar GW peak a
 mplitude Ω_GW. We also compare our predictions with current and future GW
  detection experiments.\n\nhttps://indico.ijs.si/event/3730/
