TL;DR: In this article, the authors presented high-precision timing data over time spans of up to 11 years for 45 millisecond pulsars observed as part of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) project, aimed at detecting and characterizing low-frequency gravitational waves.

TL;DR: In this paper, an isotropic stochastic GWB in the newly released 11-year data set from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) was searched for and the first pulsar-timing array (PTA) constraints that are robust against SSE errors were obtained.
