In a growing number of galaxy clusters diffuse extended radio sources have been found.
These sources are not directly associated with individual cluster galaxies. The radio …

Compact steep-spectrum (CSS) and peaked-spectrum (PS) radio sources are compact,
powerful radio sources. The multi-frequency observational properties and current theories …

The high-frequency radio sky is bursting with synchrotron transients from massive stellar
explosions and accretion events, but the low-frequency radio sky has, so far, been quiet …

The Low Frequency Array (LOFAR) is an ideal instrument to conduct deep extragalactic
surveys. It has a large field of view and is sensitive to large-scale and compact emission. It …

Source classifications, stellar masses, and star-formation rates are presented for≈ 80 000
radio sources from the first data release of the Low Frequency Array Two-metre Sky Survey …

The LOFAR Two-metre Sky Survey (LoTSS) is a deep 120–168 MHz imaging survey that will
eventually cover the entire northern sky. Each of the 3170 pointings will be observed for 8 h …

The Rapid ASKAP Continuum Survey (RACS) is the first large-area survey to be conducted
with the full 36-antenna Australian Square Kilometre Array Pathfinder (ASKAP) telescope …

We present the first full release of a survey of the 150 MHz radio sky, observed with the Giant
Metrewave Radio Telescope (GMRT) between April 2010 and March 2012 as part of the …

Abstract Using the Murchison Widefield Array (MWA), the low-frequency Square Kilometre
Array precursor located in Western Australia, we have completed the GaLactic and …

The redshifted 21 cm line is an emerging tool in cosmology, in principle permitting three-
dimensional surveys of our universe that reach unprecedentedly large volumes, previously …
