      abstract     = {Domain wall (DW) networks may have formed in the early
                      Universe following the spontaneous breaking of a discrete
                      symmetry. Notably, several particle physics models predict
                      the existence of current-carrying DWs, which can capture and
                      store particles as zero modes on it. In this study, we
                      demonstrate that gravitational waves (GWs) generated by
                      current-carrying DWs with fermionic zeromodes exhibit a
                      novel feature: an additional peak with a distinct spectral
                      shape in the GW spectrum resembling mountains, arising from
                      metastable topological remnants, which we term
                      “spherons.” This distinct signature could be detectable
                      in upcoming GW observatories such as LISA. The results
                      suggest that DW networks in beyond Standard Model scenarios
                      could emit GW signals that are significantly stronger and
                      with greater detectability than previously expected.},
