Radio – Optical Correlations in High-z Radio Galaxies and Quasars
The narrow emission line luminosities of radio-loud AGN are well-correlated with their low-frequency radio luminosities. This correlation is linear and extends over at least four orders of magnitude. The correlation is discussed in terms of a linear relationship between the power in the radio-emitting jets and the photoionizing (i.e. accretion) luminosity. Support for this theory comes from a d...
متن کاملOld stellar populations in distant radio galaxies
I describe the current status of our attempts to determine the age of the oldest known stellar populations at high redshift, in the red mJy radio galaxies 53W091 (z = 1.55) and 53W069 (z = 1.43). During the past year the original conclusion of Dunlop et al. (1996) that 53W091 is > 3 Gyr old has been questioned from two, basically orthogonal directions. First, reports that the near-infrared ligh...
متن کاملDistant Radio Galaxies and Their Environments
We review the properties and nature of luminous high-redshift radio galaxies (HzRGs, z > 2) and the environments in which they are located. HzRGs have several distinct constituents which interact with each other relativistic plasma, gas in various forms, dust, stars and an active galactic nucleus (AGN). These building blocks provide unique diagnostics about conditions in the early Universe. We ...
متن کاملProject: Multicolour Studying of Distant Radio Galaxies
Powerful radio galaxies belong to the population of massive stellar systems that can be picked at high redshifts. With measured redshift, morphology and age determination these objects can help greatly in understanding of the way of formation and evolution of giant elliptical galaxies with massive Black Holes in the Early Universe. We presents some recent results of study of the sample of 105 f...
متن کاملThe nature of the optical—radio correlations for pow- erful radio galaxies
The nature of the optical–radio correlations for powerful radio galaxies is investigated using spectroscopic observations of a complete sample of southern 2Jy radio sources. In line with previous work, we find that significant correlations exist between the luminosities of the [OIII]λ5007, [OII]λ3727 and Hβ emission lines and the radio luminosity. However, our observations are not easily reconc...
