Abstract : Galaxy clusters are the largest virialized bound structures of the universe. Recent advancement in radio observational techniques in low-frequencies has unveiled non-thermal radio features in the ICM in forms of radio halos and relics. Here, we present some new results from our group using observations of VLA, GMRT, and uGMRT. We will compare the radio results also with the X-ray counterparts and shed some light on individual merger histories of the clusters. We will mainly cover the clusters of Abell 115 and SPT-CL J2031-4037. In SPT-CL J2031-4037, we report a detailed study of a steep radio emission spectrum from halo surrounding the central Brightest Cluster of Galaxy(BGC). In addition, we present some recent results on Abell 115, a curious merging cluster.
