European astronomers used LOFAR to observe the Sausage galaxy cluster at very low radio frequencies, revealing complex diffuse radio sources and detailed properties of its relics, which provide insights into cluster dynamics and cosmic-ray electron populations.
Astronomers using the upgraded Giant Metrewave Radio Telescope (uGMRT) have discovered a second radio relic in the galaxy cluster Abell 2108. This newly found relic is larger and has a different morphology compared to the previously identified relic in the cluster. The discovery provides valuable insights into cluster mergers and emission processes, as well as the low-mass galaxy cluster's characteristics.
Astronomers using the MeerKAT radio telescope have discovered a double radio relic and an odd radio circle while observing the merging galaxy cluster PSZ2 G277.93+12.34. The double radio relic consists of two large radio relics forming a partial circle, while the odd radio circle is a mysterious gigantic ring of radio waves. The discovery could provide crucial information about cluster mergers and the resultant emission.
