DOI: 10.1051/0004-6361/202038676
Abstract: Radio galaxies with jets of relativistic particles usually are hosted by massive elliptical galaxies with active nuclei powered by accretion of interstellar matter onto a supermassive black hole (SMBH). In some rare cases ( read more here.

DOI: 10.1088/1674-4527/19/6/83
Abstract: Giant gaseous layers (termed ``superdisks'') have been hypothesized in the past to account for the strip-like radio emission gap (or straight-edged central brightness depression) observed between twin radio lobes, in over a dozen relatively nearby… read more here.

DOI: 10.1093/mnras/staa531
Abstract: In the past decade, high sensitivity radio surveys have revealed that the local radio AGN population is dominated by moderate-to-low power sources with emission that is compact on galaxy scales. High-excitation radio galaxies (HERGs) with… read more here.

DOI: 10.1093/mnras/stac1911
Abstract: Giant radio galaxies (GRGs) are radio galaxies that have projected linear extents of more than 700 kpc or 1 Mpc, depending on definition. We have carried out a careful visual inspection in search of GRGs of… read more here.

DOI: 10.1093/mnras/stad1582
Abstract: We present two- and three-dimensional hydrodynamic simulations of ∼kpc-scale AGN jets with mean jet powers in the range 1 − 7 × 1045 erg s−1, in which the jet power varies (through variation of the Lorentz… read more here.

DOI: 10.1093/mnras/stx007
Abstract: Powerful radio galaxies exist as either compact or extended sources, with the extended sources traditionally classified by their radio morphologies as Fanaroff--Riley (FR) type I and II sources. FRI/II and compact radio galaxies have also… read more here.

DOI: 10.1093/mnras/stx1631
Abstract: Previous studies have found our velocity in the rest frame of radio galaxies at high redshift to be much larger than that inferred from the dipole anisotropy of the cosmic microwave background. We construct a… read more here.
