TL;DR: These repeat bursts with high dispersion measure and variable spectra specifically seen from the direction of FRB 121102 support an origin in a young, highly magnetized, extragalactic neutron star.

TL;DR: In this paper, the authors presented FRB 121102, the first FRB discovery from a geographic location other than Parkes, which was found in the Galactic anti-center region in the 1.4?GHz Pulsar Arecibo L-band Feed Array (ALFA) survey with a DM = 557.4? 2.0 pc cm?3, pulse width of 3.0? 0.5 ms, and no evidence of interstellar scattering.

TL;DR: In this article, the authors estimate the radius, mass, and hot surface regions of the massive millisecond pulsar PSR J0740$+$6620, conditional on pulse profile modeling of Neutron Star Interior Composition Explorer X-ray Timing Instrument (NICER XTI) event data.

TL;DR: In this article, radio and X-ray observations of the only known repeating Fast Radio Burst (FRB) source, FRB 121102, were reported, along with a 5$\sigma upper bound of 0.3 mJy on any point-source continuum emission.

TL;DR: In this article, the authors report results from the initial stage of a long-term pulsar survey of the Galactic plane using the Arecibo L-band Feed Array (ALFA), a seven-beam receiver operating at 1.4 GHz with 0.3 GHz bandwidth, and fast-dump digital spectrometers.
