GW170817: Observation of Gravitational Waves from a Binary Neutron Star Inspiral.
The association of GRB 170817A, detected by Fermi-GBM 1.7 s after the coalescence, corroborates the hypothesis of a neutron star merger and provides the first direct evidence of a link between these mergers and short γ-ray bursts.
A Bright Millisecond Radio Burst of Extragalactic Origin
A 30-jansky dispersed burst, less than 5 milliseconds in duration, located 3° from the Small Magellanic Cloud is found, which implies that it was a singular event such as a supernova or coalescence of relativistic objects.
A Population of Fast Radio Bursts at Cosmological Distances
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.
PSR 1259-63 : a binary radio pulsar with a Be star companion
The discovery of the first known radio pulsar with a massive, nondegenerate companion is reported. PSR 1259-63, found during a large-scale high-frequency survey of the southern Galactic plane, has a…

Abstract Here, we present a catalogue of known Fast Radio Burst sources in the form of an online catalogue, FRBCAT. The catalogue includes information about the instrumentation used for the…
Gravitational waves from binary supermassive black holes missing in pulsar observations
It is concluded that binary evolution is either stalled or dramatically accelerated by galactic-center environments and that higher-cadence and shorter-wavelength observations would be more sensitive to gravitational waves.

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced…
Transformation of a Star into a Planet in a Millisecond Pulsar Binary
This pulsar PSR J1719−1438, a 5.7-millisecond pulsar detected in a recent survey with the Parkes 64-meter radio telescope, is shown to be in a binary system with an orbital period of 2.2 hours.
The host galaxy of a fast radio burst
The discovery of a fast radio burst is reported and the identification of a fading radio transient lasting ~6 days after the event, which is used to identify the host galaxy and measure the galaxy’s redshift, which provides a direct measurement of the cosmic density of ionized baryons in the intergalactic medium.
DiFX: A Software Correlator for Very Long Baseline Interferometry Using Multiprocessor Computing Environments
We describe the development of an FX‐style correlator for very long baseline interferometry (VLBI), implemented in software and intended to run in multiprocessor computing environments, such as large…
