High Energy Neutrinos, Gravitational Waves, and Dark Matter from a Cosmological First Order Phase Transition
This paper proposes a multimessenger framework where superheavy dark matter produced during a cosmological first-order phase transition via a filtered mechanism simultaneously explains observed high-energy neutrino events and generates a stochastic gravitational wave background, with specific mass ranges linking the signals to current or future observatories like IceCube, Cosmic Explorer, and KM3NeT.
