Relativistic and magnetized plasma ejected by radio loud AGNs through jets form the diffuse lobes of radio galaxies. The radiating particles (electron/electron–positron) in lobes emit in radio via the synchrotron process and X-ray via inverse-Compton scattering of cosmic microwave background photons. The thermal environment around radio galaxies emits X-rays via the thermal bremsstrahlung process. By combining
information from these processes we can measure physical conditions in and around the radio lobes and thus study the dynamics of radio galaxies, including double–double radio galaxies.

We present the results of multifrequency observations of two asymmetric, Mpc-scale radio sources with the Giant Metrewave Radio Telescope (GMRT) and the Very Large Array (VLA). The radio luminosity of these two sources, ...

We examine the long-term stability (on decade-like timescales) of optical ‘high polarisation’ (HP) state with popt > 3%, which commonly
occurs in flat-spectrum (i.e., beamed) radio quasars (FSRQs) and is a prominent marker ...

We present a multiwavelength study of the radio-loud narrow-line Seyfert 1 galaxy (NLSy1) 1H 0323+342, detected
by the Fermi Gamma-Ray Space Telescope. Multiband light curves show many orphan X-ray and optical flares
