We present a catalog of 349 giant radio sources (GRSs including both galaxies and
quasars). The database contains all giants known to date from the literature. These GRSs …

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 …

Giant radio sources (GRSs) are the single largest astrophysical objects known in the
Universe that have grown to megaparsec scales (≥ 0.7 Mpc). GRSs are much rarer …

There is a well-known disparity between the evolution of the star formation rate density, ψ*,
and the abundance of neutral hydrogen (H i), the raw material for star formation. Recently …

Context. The reason why some radio galaxies (RGs) grow to form so-called giant radio
galaxies (GRGs) with sizes> 700 kpc, is still unknown. Aims. In this study, we compare the …

One of the great astrophysical radio structures in the Universe is giant radio sources (GRSs)
which have a linear projected size of nearly 0.7 Mpc or more. We systematically search for …

The discovery of γ-ray emitting Seyfert galaxies has opened a new unified scheme of active
galactic nuclei (AGN) in which jetted Seyfert galaxies are viewed as young counterparts of …

The study of radio galaxies (RGs) offers valuable insights into the complex dynamics
between active galactic nuclei (AGN), host galaxies, and the surrounding medium. Among …

In this work, a theoretical model is developed for explanation of temporal evolution of
extragalactic radio sources via beaming, orientation effects and asymmetries. Equation of …
