Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

Radio astronomy has changed. For years it studied relatively rare sources, which emit
mostly non-thermal radiation across the entire electromagnetic spectrum, ie radio quasars …

The cosmological principle (CP)—the notion that the Universe is spatially isotropic and
homogeneous on large scales—underlies a century of progress in cosmology. It is …

Abstract The Very Large Array Sky Survey (VLASS) is a synoptic, all-sky radio sky survey
with a unique combination of high angular resolution (≈ 2 farcs 5), sensitivity (a 1σ goal of …

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 sky survey using the
Australian Square Kilometre Array Pathfinder (ASKAP), covering the sky south of+ 41$^\circ …

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 …

We present a detailed overview of the cosmological surveys that we aim to carry out with
Phase 1 of the Square Kilometre Array (SKA1) and the science that they will enable. We …

We present the data and initial results from the first pilot survey of the Evolutionary Map of
the Universe (EMU), observed at 944 MHz with the Australian Square Kilometre Array …
