A $\mathcal {M}\gtrsim 3$ shock in ‘El Gordo’ cluster and the origin of the radio relic
We present an X-ray and radio study of the famous `El Gordo', a massive and distant ($z=0.87$) galaxy cluster. In the deep (340 ks) Chandra observation, the cluster appears with an elongated and cometary morphology, a sign of its current merging state. The GMRT radio observations at 610 MHz reveal …
