Primordial black holes and magnetic fields in conformal neutrino mass models
Shyam Balaji, João Gonçalves, Danny Marfatia +2
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 Unive…
Supercooled phase transitions in conformal dark sectors explain NANOGrav data
João Gonçalves, Danny Marfatia, António P. Morais +1
According to recent lore, it is difficult to explain the evidence for a stochastic gravitational wave background obtained by pulsar timing arrays with supercooled first-order phase…
Gravitational waves from supercooled phase transitions in conformal Majoron models of neutrino mass
João Gonçalves, Danny Marfatia, António P. Morais +1
We study supercooled first-order phase transitions above the QCD scale in a wide class of conformal Majoron-like U(1)' models that explain the totality of active neutrino oscillati…
Gravitational waves from color restoration in a leptoquark model of radiative neutrino masses
Mårten Bertenstam, Marco Finetti, António P. Morais +2
We study the first-order phase transitions and the emerging stochastic gravitational wave spectrum in a minimal leptoquark extension of the Standard Model that explains active neut…
