Convolutional Deep Denoising Autoencoders for Radio Astronomical Images
We apply a Machine Learning technique known as Convolutional Denoising Autoencoder to denoise synthetic images of state-of-the-art radio telescopes, with the goal of detecting the faint, diffused radio sources predicted to characterise the radio cosmic web.
Ultra-Steep Spectrum Radio `Jellyfish' Uncovered in Abell 2877
We report on the discovery of a mysterious ultra-steep spectrum (USS) synchrotron source in the galaxy cluster Abell 2877.

On the alignment of haloes, filaments and magnetic fields in the simulated cosmic web
The continuous flow of gas and dark matter across scales in the cosmic web can generate correlated dynamical properties of haloes and filaments (and the magnetic fields they contain).

Magnetism Science with the Square Kilometre Array
The Square Kilometre Array (SKA) will answer fundamental questions about the origin, evolution, properties, and influence of magnetic fields throughout the Universe.

Discovering the most elusive radio relic in the sky: Diffuse Shock Acceleration caught in the act?
The case of acceleration is challenged by the low predicted efficiency of low-Mach number merger shocks, unable to explain the power observed in most radio relics.
