The 6C** sample of steep-spectrum radio sources: II – Redshift distribution and the space density of high-redshift radio galaxies
We use the 6C** sample to investigate the co-moving space density of powerful, steepspectrum radio sources. This sample, consisting of 68 objects, has virtually complete K-band photometry and spectroscopic redshifts for 32 per cent of the sources. In order to find its complete redshift distribution, we develop a method of redshift estimation based on the K − z diagram of the 3CRR, 6CE, 6C* and ...
متن کاملA complete sample of GHz-Peaked-Spectrum radio sources and its radio properties
We define a complete sample of thirty-three GHz-Peaked-Spectrum (GPS) radio sources based on their spectral properties. We present measurements of the radio spectra and polarization of the complete sample and a list of additional GPS sources which fail one or more criteria to be included in the complete sample. The majority of the data have been obtained from quasi-simultaneous multi-frequency ...
متن کاملA Sample of 669 Ultra Steep Spectrum Radio Sources to Find High Redshift Radio Galaxies ⋆
Since radio sources with Ultra Steep Spectra (USS; α ∼ < −1.30;S ∝ ν) are efficient tracers of high redshift radio galaxies (HzRGs), we have defined three samples of such USS sources using the recently completed WENSS, TEXAS, MRC, NVSS and PMN radiosurveys. Our combined sample contains 669 sources with S1400 > 10 mJy and covers virtually the entire sky outside the Galactic plane (|b| > 15). For...
متن کاملThe Bologna Complete Sample of Nearby Radio Sources
We present a new, complete, sample of 95 radio sources selected from the B2 and 3CR catalogues, with z < 0.1. Since no selection effect on the core radio power, jet velocity, or source orientation is present, this sample is well suited for statistical studies. In this first paper we present the observational status of all sources on the parsec (mas) and kiloparsec (arcsec) scale; we give new pa...
متن کاملEstimating the Number of Wideband Radio Sources
In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...
