Precise radio astrometry and new developments for the next generation of instruments
MJ Rioja, R Dodson - The Astronomy and Astrophysics Review, 2020 - Springer
We present a technique-led review of the progression of precise radio astrometry, from the
first demonstrations, half a century ago, until to date and into the future. We cover the …

First Sagittarius A* event horizon telescope results. IV. Variability, morphology, and black hole mass
In this paper we quantify the temporal variability and image morphology of the horizon-scale
emission from Sgr A*, as observed by the EHT in 2017 April at a wavelength of 1.3 mm. We …

A census of baryons in the Universe from localized fast radio bursts
More than three-quarters of the baryonic content of the Universe resides in a highly diffuse
state that is difficult to detect, with only a small fraction directly observed in galaxies and …

A single fast radio burst localized to a massive galaxy at cosmological distance
KW Bannister, AT Deller, C Phillips, JP Macquart… - Science, 2019 - science.org
Fast radio bursts (FRBs) are brief radio emissions from distant astronomical sources. Some
are known to repeat, but most are single bursts. Nonrepeating FRB observations have had …
