Abell 2256
Abell 2256 is a rich nearby galaxy cluster in the Abell catalogue that exhibits a population of ∼ 100 – 200 kpc long steep spectrum synchrotron filaments surrounding the cluster center〔(The Curious Case of Abell 2256 )〕 with significant evidence of merger activity deduced by the presence of two separate X-ray peaks in the X-ray surface brightness distribution.〔(DEEP 1.4 GHz VERY LARGE ARRAY OBSERVATIONS OF THE RADIO HALO AND RELIC IN ABELL 2256 )〕 One feature is a Large Relic other striking feature in the cluster is a Long Tail whose morphology suggests it is either a one-sided jet or a twin tail structure and the bending of the tails takes place very near the galaxy core where one might expect little impact from the galaxy’s motion through the InterGalactic medium, unless the parent galaxy undergone extreme stripping. 〔(VLA OBSERVATIONS OF ABELL 2256 )〕 ==See also==
