Giant Radio Galaxies (GRGs) are the largest structures associated with single galaxies. My aim was studying the properties of RGs in this low-frequency radio surveys. For that, I have computed the redshift, linear size, radio power, radio flux, spectral index, velocity dispersion etc.The linear size in arcminutes determined by using SAO Image DS9 . Using CASA radio fluxes were calculated.Redshift for host galaxy is found out from SDSS. Using redshift, comoving and luminosity distances were computed from NED Wright cosmological calculator. The linear size of the radio galaxies in Mpc and radio power are calculated with the help of appropriate relations. IRSA catalogue provided the WISE magnitudes for the RGs.From the data P-D diagram, WISE colour-colour plot, different histograms etc. are plotted and studied. |
