TL;DR: The VLA Low-frequency Sky Survey (VLSS) as discussed by the authors has been used to image 95% of the 3π sr of sky north of δ = -30° at a frequency of 74 MHz (4 m wavelength).

TL;DR: In this paper, a radio halo at low frequencies associated with the merging cluster Abell 521 is reported, which is consistent with a secondary origin of the relativistic electrons, but instead supports turbulent acceleration.

TL;DR: The VLSS Redux (VLSSr) as mentioned in this paper improved upon the original VLA Low-frequency Sky Survey in a number of areas including imaging of large sources, image sensitivity, and clean bias; however, the most critical improvement is the replacement of an inaccurate primary beam correction which caused source flux errors which vary as a function of radius to nearest pointing center in the VLA.

TL;DR: In this paper, the authors presented optical and near-infrared ground-based imaging results on four low-redshift damped Ly? (DLA) galaxies, which span a mixture of morphological types from patchy, irregular, and low surface brightness to spiral galaxies.
