The remnants of these radio waves occur in the form of spectacular single or double arcs at the furthest edges of galaxies.
These anomalies are of particular interest because the number of radio relics associated with merger shocks – created when galaxy clusters collide – is still small.
The researchers made the discovery with the use of South Africa’s cutting-edge MeerKAT radio telescope.
A2384 is known to be a relatively close, low-mass, complex cluster of galaxies.
