A Selection of Giant Radio Sources from NVSS
Results of the application of pattern recognition techniques to the problem of identifying Giant Radio Sources (GRS) from the data in the NVSS catalog are presented and issues affecting the process are explored. Decision-tree pattern recognition software was applied to training set source pairs developed from known NVSS large angular size radio galaxies. The full training set consisted of 51,19...
متن کاملThe spatial clustering of radio sources in NVSS and FIRST; implications for galaxy clustering evolution
We have measured the angular correlation function, w(θ), of radio sources in the 1.4 GHz NVSS and FIRST radio surveys. Below ∼ 6′ the signal is dominated by the size distribution of classical double radio galaxies, an effect underestimated in previous studies. We model the physical size distribution of FRII radio galaxies to account for this excess signal in w(θ). The amplitude of the true cosm...
متن کاملA Search for Sub-millisecond Pulsations in Unidentified FIRST and NVSS Radio Sources
We have searched 92 unidentified sources from the FIRST and NVSS radio catalogs for pulsations at 610 MHz. The selected sources are bright, have no identifications, are unresolved and have significant linear polarization. Our search was sensitive to sub-millisecond pulsations from pulsars with a large range of dispersion measures. We have detected no radio pulsations from these sources and conc...
متن کاملA Combined EIS-NVSS Survey Of Radio Sources II: Infrared imaging and the K–z relation
The Combined EIS-NVSS Survey Of Radio Sources (CENSORS) is a 1.4 GHz radio survey selected from the NRAO VLA Sky Survey (NVSS) and complete to a fluxdensity of 7.2mJy. It targets the ESO Imaging Survey (EIS) Patch D, which is a 3 by 2 square degree field centred on 09 51 36.0 -21 00 00 (J2000). This paper presents K–band imaging of 142 of the 150 CENSORS sources. The primary motivation for begi...
متن کاملCENSORS: A Combined EIS-NVSS Survey Of Radio Sources. I. Sample definition, radio data and optical identifications
A new sample of radio sources, with the designated name CENSORS (A Combined EISNVSS Survey Of Radio Sources), has been defined by combining the NRAO VLA Sky Survey (NVSS) at 1.4 GHz with the ESO Imaging Survey (EIS) Patch D, a 3 by 2 degree region of sky centred at 09 51 36.0, −21 00 00 (J2000). New radio observations of 199 NVSS radio sources with NVSS flux densities S1.4 GHz > 7.8 mJy are pre...
