Possenti,W. van Straten,W. van Straten +28 more
TL;DR: The detection of four nonrepeating radio transient events with millisecond duration in data from the 64-meter Parkes radio telescope in Australia indicates that these radio bursts had their origin outside the authors' galaxy, but it is not possible to tell what caused them.
Journal ArticleDOI

Pennucci,Renée Spiewak,Ingrid H. Stairs,Kevin Stovall,Joseph K. Swiggum,Weiwei Zhu +28 more
TL;DR: In this article, the authors measured the mass of the MSP J0740+6620 to be ${\mathbf{2.14} + 2.09} + 0.10% credibility interval.

TL;DR: In this article, the relativistic Shapiro delay (Shapiro 1964) was used to estimate the masses of a pulsar binary system, and the mass of the binary system was found to be 2.14+0.10−0.18−1.

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.
