The giant radio galaxy 8C 0821+695 and its environment
We present new VLA and Effelsberg observations of the radio galaxy 8C 0821+695. We have obtained detailed images in total intensity and polarization of this 2 Mpc sized giant. The magnetic field has a configuration predominantly parallel to the source main axis. We observe Faraday rotation at low frequencies, most probably produced by an ionized medium external to the radio source. The spectral...
متن کاملDust, Gas and the Evolutionary Status of the Radio Galaxy, 8c 1435+635, at Z = 4.25
We present the results of new rest-frame far-IR observations of the z = 4.25 radio galaxy, 8C1435+635, which not only confirm that it contains an enormous quantity of dust (as first inferred from its mm-wave detection by Ivison 1995) but also allow the first meaningful constraints to be placed on the mass of this dust and associated gas. The new measurements consist of: (i) clear detections of ...
متن کاملThe radio galaxy 1138−262 at z=2.2: a giant elliptical galaxy at the center of a proto-cluster?
We present a detailed observational study of a remarkable radio galaxy at a redshift of z = 2.2: 1138-262. This objectwas selected fromour compendiumof ultra steep spectrum radio sources on the basis of its distorted radio morphology. High resolution VLA radio observations show that the radio source consists of a series of knots and jet-like protrusions, with a sharp bend, strongly suggesting t...
متن کاملRadio Galaxy Clustering at z ∼ 0.3
Radio galaxies are uniquely useful as probes of large-scale structure as their uniform identification with giant elliptical galaxies out to high redshift means that the evolution of their bias factor can be predicted. As the initial stage in a project to study large-scale structure with radio galaxies we have performed a small redshift survey, selecting 29 radio galaxies in the range 0.19 < z <...
متن کاملSpt 0538−50: Physical Conditions in the Ism of a Strongly Lensed Dusty Star-forming Galaxy at Z=2.8
We present observations of SPT-S J053816−5030.8, a gravitationally-lensed dusty star forming galaxy (DSFG) at z = 2.7817, first discovered at millimeter wavelengths by the South Pole Telescope. SPT 0538−50 is typical of the brightest sources found by wide-field millimeter-wavelength surveys, being lensed by an intervening galaxy at moderate redshift (in this instance, at z = 0.441). We present ...
