Deep Extragalactic VLBI - Optical Survey ( DEVOS ) II . Efficient VLBI
Context. The Deep Extragalactic VLBI-Optical Survey (DEVOS) aims at constructing a large sample of compact radio sources up to two orders of magnitude fainter than those studied in other Very Long Baseline Interferometry (VLBI) surveys. Optical identification of the objects is ensured by selecting them from the Sloan Digital Sky Survey (SDSS) list. Aims. While continuing to build up the DEVOS d...
متن کاملGHz VLBI survey of compact radio sources ?
We present results from 86 GHz VLBI1 observations of 28 compact radio sources made in April 1993. All but two of the observed objects are active galactic nuclei. The remaining two objects are the galactic center Sgr A∗ and the X-ray binary star Cygnus X-3. Of the observed sources, 26 have yielded fringe detections. We present correlated flux densities, estimate the maximum observed brightness t...

متن کاملDeep Extragalactic VLBI-Optical Survey (DEVOS) I. Pilot MERLIN and VLBI observations
We present the results of the pilot observations of the Deep Extragalactic VLBI-Optical Survey (DEVOS). Our ultimate aim is to collect information on compact structures in a large sample of extragalactic radio sources (∼ 10 objects) up to two orders of magnitude fainter than those studied in typical imaging Very Long Baseline Interferometry (VLBI) surveys up until now. This would lead to an unp...
