Axionic domain walls at Pulsar Timing Arrays: QCD bias and particle friction
Abstract The recent results from the Pulsar Timing Array (PTA) collaborations show the first evidence for the detection of a stochastic background of gravitational waves at the nHz frequencies. This discovery has profound implications for the physics of both the late and the early Universe. In fact,...
