TL;DR: The NANOGrav Collaboration found strong Bayesian evidence for a common-spectrum stochastic process in its 12.5-yr pulsar timing array (PTA) dataset, with median characteristic strain amplitude at periods of a year of $A_{\rm yr} = 1.92^{+0.75}_{-0.55} \times 10^{-15} as mentioned in this paper.
