NGC 4654: polarized radio continuum emission as a diagnostic tool for a galaxy--cluster interaction [PDF]
, 2006 A recent comparison between deep VLA HI observations and dynamical models of the Virgo cluster spiral galaxy NGC 4654 has shown that only a model involving a combination of a tidal interaction and ram pressure can reproduce the data.

A MATURE GALAXY CLUSTER AT z = 1.58 AROUND THE RADIO GALAXY 7C 1753+6311 [PDF]
, 2015 We report on the discovery of a z = 1.58 mature cluster around the high-redshift radio galaxy 7C 1753+6311, first identified in the Clusters Around Radio-loud active galactic nuclei survey.

Extremely Red Radio Galaxies [PDF]
, 2001 At least half the radio galaxies at z>1 in the 7C Redshift Survey have extremely red colours (R-K>5), consistent with stellar populations which formed at high redshift (z>5). We discuss the implications of this for the evolution of massive galaxies in general and for the fraction of near-IR-selected EROs which host AGN, a result which is now ...

A Comprehensive Observational Study of the FRB 121102 Persistent Radio Source
The Astrophysical Journal, 2023 FRB 121102 is the first fast radio burst to be spatially associated with a persistent radio source (QRS 121102), the nature of which remains unknown. We constrain the physical size of QRS 121102 by measuring its flux-density variability with the VLA from

Discovery of a new radio galaxy within the error box of the unidentified gamma-ray source 3EG J1735-1500 [PDF]
, 2003 We report the discovery of a new radio galaxy within the location error box of the gamma-ray source 3EG J1735-1500. The galaxy is a double-sided jet source forming a large angle with the line of sight.

The Astrophysical Journal, 2023 We present Karl G. Jansky Very Large Array K -band (19 GHz) observations of the redshifted CO(1–0) line emission toward the radio galaxy TN J0924−2201 at z = 5.2, which is one of the most distant radio galaxies with CO detected.

Discovery of Rare Dying Radio Galaxies Using MeerKAT
Galaxies, 2021 Dying radio galaxies represent a stage of the evolution of active galactic nuclei (AGN), during which the accreting central black hole has switched off and/or falls to such a low level that the plasma outflow can no longer be sustained. When this happens,

The environment of radio galaxies: A signature of AGN feedback at high redshifts [PDF]
, 2017 We use the semi-analytical model of galaxy formation GALFORM to characterise an indirect signature of AGN feedback in the environment of radio galaxies at high redshifts. The predicted environment of radio galaxies is denser than that of radio-quiet galaxies with the same stellar mass. This is consistent with observational results from the CARLA survey.

B_gg revisited: The environments of low-excitation radio galaxies and unified models [PDF]
Astron.Astrophys. 414 (2004) 927-929, 2003 Recent measurements of the galaxy clustering environments around intermediate-redshift radio sources have suggested a systematic environmental difference between radio galaxies and radio-loud quasars, in contradiction to the predictions of simple unified models for the two classes of object. I show that the apparent difference arises mainly as a result

ИССЛЕДОВАНИЕ УГЛОВОЙ СТРУКТУРЫ РАДИОГАЛАКТИКИ 3С265 НА ДЕКАМЕТРОВЫХ ВОЛНАХ
Odessa Astronomical Publications, 2011 The results of study of the radio galaxy 3C265 at decameter wavelengths are presented. As the high frequency map of the radio source the decameter model of its angular structure contains two extended lobes and three compact hot spots. Its coordinates are
