The current standard cosmological model is constructed within the framework of general
relativity with a cosmological constant Λ, which is often associated with dark energy, and …

Context. The Low Frequency Array (LOFAR) is the only existing radio interferometer able to
observe at ultra-low frequencies (< 100 MHz) with high resolution (< 15") and high sensitivity …

We present deep 1.4 GHz source counts from∼ 5 deg2 of the continuum Early Science data
release of the MeerKAT International Gigahertz Tiered Extragalactic Exploration survey …

Context. Apertif is a phased-array feed system for the Westerbork Synthesis Radio
Telescope, providing forty instantaneous beams over 300 MHz of bandwidth. A dedicated …

Abell 3266 is a massive and complex merging galaxy cluster that exhibits significant
substructure. We present new, highly sensitive radio continuum observations of Abell 3266 …

The Australian SKA Pathfinder (ASKAP) is being used to undertake a campaign to rapidly
survey the sky in three frequency bands across its operational spectral range. The first pass …

Odd radio circles (ORCs) are recently-discovered faint diffuse circles of radio emission, of
unknown cause, surrounding galaxies at moderate redshift (z∼ 0.2–0.6). Here, we present …

In this work, we examine the classification accuracy and robustness of a state-of-the-art semi-
supervised learning (SSL) algorithm applied to the morphological classification of radio …

We describe a new low-frequency wideband radio survey of the southern sky. Observations
covering 72–231 MHz and Declinations south of have been performed with the Murchison …

Many relaxed cool-core clusters host diffuse radio emission on scales of hundreds of
kiloparsecs: mini-haloes. However, the mechanism responsible for generating them, as well …
