These high sensitivity and high resolution observations have shown that some FR I and FR II sources have luminosities on the wrong side of the dividing line. The existence of a set of sources – Hybrid Morphology Radio Sources (HyMoRS) – containing within them exhibiting FR I and FR II structures on opposite side of the same active nucleus makes the situation even more intriguing. We are studying a sample of HyMoRS selected from the MeerKAT Galaxy Cluster Legacy Survey (MGCLS) with (i) known spectroscopic redshift, differing from that of the redshift of the host cluster by no more than 1000 km s–1 (ii) angular size $>$4 arcmin (iii) declination range [0, –50] degrees , and (iv) located at different distances from the center of the cluster. Radio images of the sample using the GMRT and MGCLS are being used to investigate the influence of the environment on the morphology. Here, we present preliminary results of these observations. |
