| Abstract : | We undertook a study using the upgraded Giant Meterwave Radio Telescope (uGMRT) to investigate a characteristic wide angle-tail radio source J1051+5523 in the nearby Universe. Recent studies of galaxy clusters employing spectroscopy from the Sloan Digital Sky Survey (SDSS) confirm that the host of J1051+5523 is the Brightest Cluster Galaxy (BCG) of the cluster WHL J105147.4+552309. Situated at a redshift of 0.074, the source exhibits a projected linear size of approximately 490 kiloparsecs. We conducted observations of the source using both Band 3 (250-500 MHz) and Band 4 (550-850 MHz) on uGMRT. The collected data were flagged, calibrated, and imaged using the CAPTURE pipeline for uGMRT. The resulting high-resolution radio maps from uGMRT revealed distinctive and previously unseen morphological characteristics throughout the source. The northern lobe displays an unusual bend at an almost right angle towards the east. In the southern lobe, we observed structures with multiple bends. By combining archival LOFAR Two-Meter Sky Survey (LOTSS) data with Band 3 and Band 4 data, we created spectral index maps to analyse the behaviour of the source across the electromagnetic spectrum. Given its association with a cluster and its residence in a BCG, this comprehensive study of the source across multiple frequencies is likely to provide valuable insights into how the surrounding environment influences the morphology and evolution of the source. |
