ISO observations of a sample of Compact Steep Spectrum and GHz Peaked Spectrum Radio Galaxies
We present results from observations obtained with ISOPHOT, on board the ISO satellite, of a representative sample of seventeen CSS/GPS radio galaxies and of a control sample of sixteen extended radio galaxies spanning similar ranges in redshift (0.2 ≤ z ≤ 0.8) and radio luminosity (P2.7GHz ≥ 10 W/Hz). The observations have been performed at λ = 60, 90, 174 and 200 μm. The original purpose of t...
متن کاملThe host galaxies of Compact Steep Spectrum and Gigahertz-Peaked Spectrum radio sources
I will review some of the developments in studies of the host galaxy properties of Compact Steep Spectrum (CSS) and GigaHertz-Peaked Spectrum (GPS) radio sources. In contrast to previous reviews structured around observational technique, I will discuss the host galaxy properties in terms of morphology, stellar content and warm gas properties and discuss how compact, young radio-loud AGN are key...
متن کاملExtended and Compact X-ray Emission in Powerful Radio Galaxies
We report ROSAT X-ray observations of two powerful radio galaxies. 3C 280 provides evidence for a mixture of unresolved and extended emission, with the latter produced by hot plasma of insufficient pressure to confine the radio lobes and insufficient density for a cooling flow to have begun. 3C 220.3 gives only an X-ray upper limit, but one consistent with our interpretation of the X-ray emissi...
متن کاملUltra–Steep Spectrum Radio Galaxies at Hy Redshifts
Radio sources have traditionally provided convenient beacons for probing the early Universe. Hy Spinrad was among the first of the tenacious breed of observers who would attempt to obtain optical identifications and spectra of the faintest possible ‘radio galaxies’ to investigate the formation and evolution of galaxies at hy redshift. Modern telescopes and instruments have made these tasks much...
متن کاملNear-infrared spectroscopy of powerful compact steep-spectrum radio sources
We have obtained near-infrared spectroscopy of a small sample of powerful Compact Steep-Spectrum (CSS) radio sources mainly, but not exclusively, from the 3CR sample. We find no differences between the distributions in the equivalent width and luminosity of the [Oiii]5007 line for our sample and other larger, presumably older, high-redshift 3C objects, suggesting that the underlying quasar lumi...
