TL;DR: The Very Large Array Sky Survey (VLASS) as discussed by the authors is a synoptic, all-sky radio sky survey with a unique combination of high angular resolution (≈2.5"), sensitivity (a 1σ goal of 70 μJy/beam in the coadded data), full linear Stokes polarimetry, time domain coverage, and wide bandwidth (2-4 GHz).

TL;DR: In this paper, radio observations of Betelgeuse have been used to reveal the temperature structure of the extended atmosphere from two to seven times the photospheric radius of the star, showing that the atmosphere has an irregular structure and a temperature (3,450 ± 850 K) consistent with the photosphere temperature but much lower than that of gas in the same region probed by optical and ultraviolet observations.

TL;DR: The Long Baseline Campaign (LBC) was carried out from 2014 September to late November, culminating in end-to-end observations, calibrations, and imaging of selected Science Verification (SV) targets as discussed by the authors.

TL;DR: Twenty consecutive Very Long Baseline Interferometry images of supernova 1993J from the time of explosion to the present show the dynamic evolution of the expanding radio shell of an exploded star.

TL;DR: The results of a second epoch VLBA Calibrator Survey campaign (VCS-II) in which 2400 VCS sources were re-observed at X and S bands in order to improve the upcoming third realization of the International Celestial Reference Frame (ICRF3) as well as to improve their usefulness as VLBI phase reference calibrators.
