TL;DR: In this article, the authors describe the International Pulsar Timing Array second data release, which includes recent pulsar timing data obtained by three regional consortia: the European Pulsars Timing array, the North American Nanohertz Observatory for Gravitational Waves, and the Parkes pulsar timing array, and find that the timing precisions of pulsars are generally improved compared to the previous data release.

TL;DR: In this article, the authors present results from the search for a stochastic gravitational-wave background (GWB) as predicted by the theory of General Relativity using six radio millisecond pulsars from the Data Release 2 (DR2) of the European Pulsar Timing Array (EPTA) covering a timespan up to 24 years.
