The quest of CMB spectral distortions to probe the scalar-induced gravitational wave background interpretation in PTA data

Gravitational Waves (GW) sourced by second-order primordial curvature fluctuations are among the favoured models fitting the recent Pulsar Timing Array (PTA) measurement of a Stochastic GW Background (SGWB). We study how spectral distortions (SDs) and anisotropies of the Cosmic Microwave Background...
