Radio telescopes confirm 3.3-million-light-year halo in unusually quiet galaxy cluster
Astronomers using the uGMRT and MeerKAT radio telescopes have studied the galaxy cluster RXCJ0232–4420 and found it hosts a giant radio halo extending over 3.3 million light years. The cluster, first discovered in 2002, contains two central bright galaxies and shows both diffuse radio emission and a large radio relic structure. The observations revealed relatively uniform spectral properties, suggesting charged particles are being re-accelerated throughout … Continue reading Radio telescopes confirm 3.3-million-light-year halo in unusually quiet galaxy cluster
