Red galaxy overdensities and the varied cluster environments of powerful radio sources with z ∼ 1 . 6
The environments of a complete subsample of 6 of the most powerful radio–loud AGN at redshifts z ∼ 1.6 are investigated, using deep RJK imaging to depths of R ∼ 26, J ∼ 22.4 and K ∼ 20.6. An excess of galaxy counts in the K–band is seen across these fields; these surplus galaxy counts are predominantly associated with red galaxies (R − K ∼ > 4) of magnitudes 17.5 ∼ < K ∼ < 20.5 found within rad...
متن کاملThe cluster environments of radio loud quasars
We have carried out multi-colour imaging of the fields of a statistically complete sample of low-frequency selected radio loud quasars at 0.6 < z < 1.1, in order to determine the characteristics of their environments. The largest radio sources are located in the field, and smaller steep-spectrum sources are more likely to be found in richer environments, from compact groups through to clusters....
متن کاملThe Evolution of Diffuse Radio Sources in Galaxy Clusters
We investigate the evolution and number distribution of radio halos in galaxy clusters. Without re-acceleration or regeneration, the relativistic electrons responsible for the diffuse radio emission will lose their energy via inverse-Compton and synchrotron losses in a rather short time, and radio halos will have lifetimes ∼ 0.1 Gyr. Radio halos could last for ∼ Gyr if a significant level of re...
متن کاملChandra observations of dying radio sources in galaxy clusters ⋆
Context. The dying radio sources represent a very interesting and largely unexplored stage of the active galactic nucleus (AGN) evolution. They are considered to be very rare, and almost all of the few known ones were found in galaxy clusters. However, considering the small number detected so far, it has not been possible to draw any firm conclusions about their X-ray environment. Aims. We pres...
متن کاملRadio Observations of Galaxy Clusters: Connection to Cluster Mergers
The main component of the intracluster medium (ICM) in clusters of galaxies is represented by the X-ray emitting thermal plasma. In addition, the presence of relativistic electrons and largescale magnetic fields in a fraction of galaxy clusters is demonstrated by the detection of largescale synchrotron radio sources, which have no optical counterpart and no obvious connection to the cluster gal...
