Unraveling the Core of a Distant Galaxy Cluster through Radio Signals

Astronomers investigating an anomalous radio emission from the galactic cluster Abell 1213 have discovered that it may come from the 1.66 million light-year-long radio tail of its dominating central galaxy, 4C29.41. The team also found evidence of mergers between galaxies in the cluster, which is located around 647 million light-years from Earth. The radio emission is not a radio halo, but rather a radio relic, possibly caused by a past galactic merger. The cluster's core has an intricate substructure, and star-forming galaxies are not restricted to the edges of Abell 1213.

New insights into radio emission from Abell 1213 cluster.

European astronomers have observed the galaxy cluster Abell 1213 using various spacecraft and ground-based facilities, unveiling essential information about the diffuse radio emission from this source. The observations found that Abell 1213 exhibits disturbed dynamics and is composed of several galaxy groups. The diffuse radio emission has a size of about 1.66 million light years and may be a tail of the central radio galaxy 4C29.41 bent by the interaction with the intracluster medium. The source of radio emission in Abell 1213 may be a radio relic, and deeper X-ray observations are necessary to draw final conclusions regarding the nature of its diffuse radio emission.
