Supercooled phase transitions in conformal dark sectors explain NANOGrav data
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 transitions (FOPTs). We demonstrate that supercooled FOPTs in dark U(1)′ models with a conformal dark sector easily exp...

| Summary: | 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 transitions (FOPTs). We demonstrate that supercooled FOPTs in dark U(1)′ models with a conformal dark sector easily explain the nHz signal at NANOGrav. |
