As though cooking up models of the early universe that produce an interesting number of primordial black holes wasn’t hard enough, now we’ve got quantum effects to worry about too. Today’s authors quantify how careful we need to be with models of ultra-slow-roll inflation in order to predict the correct number of primordial black holes that could be around today.
