Re-acceleration in the lobes of giant radio galaxies
AIP Conference Proceedings, 2005 Giant radio sources (GRSs), defined to be those with a projected linear size ≳1 Mpc, are the largest single objects in the Universe, and are useful for probing a number of astrophysical questions. The lobes of radio emission in these sources extend for hundreds of kpc from the initial acceleration regions, called hotspots, towards the nuclear regions ...

Unveiling the nature of giant radio galaxies [PDF]
, 2021 The thesis deals with the study of giant radio galaxies (GRGs), which are radio galaxies of megaparsec sizes. Their enormous size and rarity have been investigated in this thesis. The study included searching and consequent finding of the largest samples

EVOLUTION FEATURES OF GIANT SOURCES WITH LINEAR AND BREAK STEEP RADIO SPECTRA
Odessa Astronomical Publications, 2017 In the framework of the cosmological model CDM the features of properties of giant radio sources with steep low-frequency spectra of linear (S) and break (C+) types are examined.

The particle content of low-power radio galaxies in groups and clusters [PDF]
, 2013 The synchrotron-radiating particles and magnetic fields in low-power radio galaxies (including most nearby cluster-centre sources), if at equipartition, can provide only a small fraction of the total internal energy density of the radio lobes or plumes ...

Looking for Signatures of AGN Feedback in Radio-Quiet AGN
Galaxies, 2023 In this article, we discuss the state of “AGN feedback” in radio-quiet (RQ) AGN. This study involves heterogeneous samples of nearby Seyfert and LINER galaxies as well as quasi-stellar objects (QSOs) that have been observed at low radio frequencies (few ∼

Giant radio galaxies: Old long-lived quasars? [PDF]
Astronomy Reports, 2009 Based on the miscellaneous published radio and optical data, SDSS and APM catalogue we consider the various properties of the giant radio sources (gRS) with the aim of refining the conditions leading to the formation of these objects. We compare gRSs with the regular-sized radio sources in radio and optical bands, yielding the following results: 1. The

On the Encounter between the GASP Galaxy JO36 and the Radio Plume of GIN 049
The Astrophysical Journal, 2023 We report the serendipitous discovery of an unprecedented interaction between the radio lobe of a radio galaxy and a spiral galaxy. The discovery was made thanks to LOFAR observations at 144 MHz of the galaxy cluster A160 ( z = 0.04317) provided by the ...

Giant radio galaxies and cosmic web [PDF]
Proceedings of the International Astronomical Union, 2014 AbstractGiant radio galaxies create the well distinguishable class of sources. These sources are characterized with edge-brightened radio lobes with highly collimated radio jets and large linear sizes which make them the largest individual structures in the Universe.
