Abstract

Abstract: Using the 144 MHz Low-Frequency Array (LOFAR) telescope, We undelook a search for Miscellaneous Radio Galaxies (MRGs) whose morphological structures are different from known structures. Reseaons of study of these type sources due to their unique and peculiar morphology. Here, we report four MRGs from LOFAR Two Metre Sky Survey first data release (LoTSS DR1) at 144 MHz frequency. The MRS is identified manual visual search (MVS) from LoTSS DR1 data catalogue. We also check their radio morphology from other surveys like The NRAO VLA Sky Survey (NVSS) at 1400 MHz. The corresponding optical counterparts are also identified from Sloan Digital Sky Survey (SDSS), where available. We have estimated different physical parameters like spectral index, radio luminosity, radio power of these MRGs.
