Journal ArticleDOI

Shami Chatterjee,Casey J. Law,Robert Wharton,Sarah Burke-Spolaor,Sarah Burke-Spolaor,Jason W. T. Hessels,Jason W. T. Hessels,Geoffrey C. Bower,James M. Cordes,Shriharsh P. Tendulkar,C. G. Bassa,Paul Demorest,Bryan J. Butler,Andrew Seymour,P. Scholz,Matthew W. Abruzzo,Slavko Bogdanov,V. M. Kaspi,A. Keimpema,T. J. W. Lazio,Benito Marcote,Maura McLaughlin,Zsolt Paragi,Scott M. Ransom,Michael P. Rupen,Laura Spitler,H. J. van Langevelde,H. J. van Langevelde +27 more
TL;DR: The authors' observations are inconsistent with the fast radio burst having a Galactic origin or its source being located within a prominent star-forming galaxy, and the source appears to be co-located with a low-luminosity active galactic nucleus or a previously unknown type of extragalactic source.

TL;DR: In this article, the precise localization of the repeating fast radio burst (FRB 121102) has provided the first unambiguous association (chance coincidence probability p ≲ 3 × 10−4) of an optical and persistent radio counterpart.

TL;DR: Multi-frequency radio measurements of a newly discovered pulsar close to the Galactic Centre are reported and it is shown that the pulsar’s unusually large Faraday rotation indicates that there is a dynamically important magnetic field near the black hole.
Journal ArticleDOI

TL;DR: In this paper, the authors report on timing, flux density, and polarimetric observations of the transient magnetar and 5.54 s radio pulsar XTE J1810-197 using the GBT, Nancay, and Parkes radio telescopes beginning in early 2006, until its sudden disappearance as a radio source in late 2008.

TL;DR: Observations of FRB 121102 show almost 100 per cent linearly polarized emission at a very high and variable Faraday rotation measure, demonstrating that the fast radio burst source is in an extreme and dynamic magneto-ionic environment, and the short durations of the bursts suggest a neutron star origin.
