Radio galaxy feedback in X-ray selected groups from COSMOS: the effect on the ICM [PDF]
We quantify the importance of the mechanical energy released by radio-galaxies inside galaxy groups. We use scaling relations to estimate the mechanical energy released by 16 radio-AGN located inside X-ray detected galaxy groups in the COSMOS field.

ИССЛЕДОВАНИЕ УГЛОВОЙ СТРУКТУРЫ РАДИОГАЛАКТИКИ 3С265 НА ДЕКАМЕТРОВЫХ ВОЛНАХ
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

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.

Galaxy groups constitute the most common class of galaxy systems in the known Universe, unique in terms of environmental properties. However, despite recent advances in optical and infrared observations as well as in theoretical research, little is known

Extremely Red Radio Galaxies [PDF]
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 ...

PKS2250-41: a case study for triggering
We present the results of a multiwavelength study of the z = 0.31 radio source PKS2250-41. Integral field unit and long-slit spectroscopy obtained using VIMOS and FORS1 on the VLT, and archival HST optical imaging observations are used to study the ...

An Extended Lyα Outflow from a Radio Galaxy at z = 3.7?
Spatially resolved observations of active galactic nuclei (AGN) host galaxies undergoing feedback processes are one of the most relevant avenues through which galactic evolution can be studied, given the long-lasting effects AGN feedback has on gas ...

Discovery of Rare Dying Radio Galaxies Using MeerKAT
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 gaseous environments of radio galaxies [PDF]
X-ray emission traces the gaseous environments of radio sources. The medium must be present for jet confinement, but what are its influence on jet fuelling, dynamics, propagation, and disruption? The observational situation is both complicated and enriched by radio sources being multi-component X-ray emitters, with several possible regions of non ...
