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, the authors presented the most extensive catalog of Faraday rotation data of compact extragalactic polarized radio sources to date, and used a recently developed algorithm that reconstructs the map and the power spectrum of a statistically isotropic and homogeneous field while taking into account uncertainties in the noise statistics.

TL;DR: The science case and observational strategy for the Very Large Array Sky Survey is presented, and also results from early survey observations are presented.
Journal ArticleDOI
Magnetic field strength and spectral distribution of six parsec-scale active galactic nuclei jets
TL;DR: In this article, the position of the radio core from the base of a conical jet was estimated using the frequency-dependent position of their VLBI cores and their overall jet spectral distribution.
