In this work, we construct promising model-building routes towards SO (10) grand unified
theory inflation and examine their ability to explain the recent pulsar timing arrays (PTAs) …

The stochastic signal detected by pulsar timing arrays (PTAs) has raised great interest in
understanding its physical origin. Assuming the signal is a cosmological gravitational-wave …

The recently released data by pulsar timing array (PTA) collaborations have amassed
substantial evidence corroborating the existence of a stochastic signal consistent with a …

A stochastic gravitational wave background is a prediction of a number of astrophysical and
cosmological phenomena including early Universe cosmology. Recently, the NANOGrav …

Recently, Pulsar Timing Array (PTA) Collaborations have detected a stochastic gravitational
wave background (SGWB) at nano-Hz frequencies, with domain wall networks (DWs) …

Recently, several major pulsar timing array (PTA) collaborations have assembled strong
evidence for the existence of a gravitational-wave background at frequencies around the …

The gravitational wave (GW) signal offers a promising window into the dynamics of the early
Universe. The recent results from the pulsar timing arrays (PTAs) could be the first glimpse of …

The data recently released by the North American Nanohertz Observatory for Gravitational
Waves provides compelling evidence supporting the existence of a stochastic signal that …

The compelling evidence for the detection of the stochastic gravitational wave background
by NANOGrav imposes constraints on the mass of compact cores of ultra-light dark matter …

The existence of a stochastic gravitational wave background is indicated by the recent
pulsar timing array (PTA) experiments. We study the enhanced production of second-order …
