Primordial black holes and magnetic fields in conformal neutrino mass models
Sufficiently strong and long-lasting first-order phase transitions can produce primordial black holes (PBHs) that contribute substantially to the dark matter abundance of the Universe, and can produce large-scale primordial magnetic fields. We study these mechanisms in a generic class of conformal U(1)'models that also explain active neutrino oscillation data via the type-I seesaw mechanism. We fi
