Stacked Fermi-LAT observations reveal a 32-sigma cumulative gamma-ray signal from 172 individually undetected extreme blazars, with an average photon index of 2.08 and a predicted contribution of at least 10% to the extragalactic gamma-ray background at 100 GeV.

{\it Fermi}-LAT Stacking Analysis Technique: An Application to Extreme Blazars and Prospects for their CTA Detection
