VLBI Polarimetry of 177 Sources from the Caltech-Jodrell Bank Flat-spectrum Survey
We present VLBA observations and a statistical analysis of 5 GHz VLBI polarimetry data from 177 sources in the Caltech-Jodrell Bank flat-spectrum (CJF) survey. The CJF survey, a complete, flux-density-limited sample of 293 extragalactic radio sources, gives us the unique opportunity to compare a broad range of source properties for quasars, galaxies and BL Lacertae objects. We focus primarily o...
متن کاملThe Caltech–Jodrell Bank VLBI Surveys
The Caltech–Jodrell Bank VLBI surveys of bright extragalactic radio sources north of declination 35 were carried out between 1990 and 1995 using the Mark-II system, achieving images with a resolution of about 1 mas at 5 GHz. The CJ1 survey (together with the older ‘PR’ survey) includes 200 objects with 5 GHz flux density greater than 0.7 Jy; the CJ2 survey includes 193 flat-spectrum sources wit...
متن کاملThe Identification of EGRET Sources with Flat-Spectrum Radio Sources
We present a method to assess the reliability of the identification of EGRET sources with extragalactic radio sources. We verify that EGRET is detecting the blazar class of AGN. However, many published identifications are found to be questionable. We provide a table of 42 blazars which we expect to be robust identifications of EGRET sources. This includes one previously unidentified EGRET sourc...
متن کاملEVN observations of eleven GHz - Peaked - Spectrum radio sources at 2 . 3 / 8 . 4 GHz
We present results of EVN observations of eleven GHz-Peaked-Spectrum (GPS) radio sources at 2.3/8.4 GHz. These sources are from the classical " bright " GPS source samples with peak flux densities > 0.2 Jy and spectral indices α < −0.2 (S ∝ ν −α) in the optically thick regime of their convex spectra. Most of the target sources did not have VLBI images at the time this project started. The aim o...
متن کاملNew candidate GHz Peaked Spectrum and Compact Steep Spectrum Sources
Data from a recent Australia Telescope Compact Array (ATCA) program of multi-frequency, multi-epoch monitoring of 202 active galactic nuclei with declinations < +10 • have been searched for GHz Peaked Spectrum (GPS) and Compact Steep Spectrum (CSS) radio sources. Supplementary data at higher and lower frequencies, where available, have been used to further examine the spectral properties of pre...
