Abstract : We report the discovery of a radio relic emission at the peripheral cluster region using upgraded GMRT. The spatially resolved radio relic emission show an elongated, bar-shaped structure, whose size is 72 kpc x 152 kpc. Our study with the multi-wavelength GMRT data and Chandra data shows that across the radio relic there is a hint of a surface brightness edge in the hot X-ray gas. We also detect flattening of the radio spectral index as the old plasma at the near end of surface brightness edge is reinvigorated by the passage of shock and shows the expected change in radio emission characteristics. We suggest that the radio relic has been seeded by the lobes of the AGN, demonstrating the connection between AGNs and radio relics.
