      abstract     = {We consider black hole formation due to the gravitational
                      collapse produced by large density fluctuations during an
                      epoch of reheating with a stiff equation of state and
                      calculate the induced gravitational wave spectrum. By
                      considering the existing bounds on the total energy density
                      of gravitational waves today, we find constraints on the
                      parameter space of this scenario. We also calculate the
                      lepton asymmetry generated by metric perturbations via the
                      chiral gravitational anomaly present in the Standard Model
                      and find that, once the electroweak sphaleron processes have
                      taken place, the large spectrum of scalar perturbations
                      responsible for black hole formation induces a peak in the
                      baryon asymmetry fluctuations on small scales.},
