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.

TL;DR: Only one repeating fast radio burst has been localized, to an irregular dwarf galaxy; now another is found to come from a star-forming region of a nearby spiral galaxy, suggesting that repeating FRBs may have a wide range of luminosities, and originate from diverse host galaxies and local environments.
