An optical spectroscopic survey of the 3CR sample of radio galaxies with z<0.3. II. Spectroscopic classes and accretion modes in radio-loud AGN
Sara Buttiglione, Alessandro Capetti, Annalisa Celotti +4
We use the emission line measurements of 3CR radio sources with redshift < 0.3, to explore their spectroscopic properties. The 3CR sources show a bimodal distribution of Excitation…
Properties and environment of Radio Emitting Galaxies in the VLA-zCOSMOS survey
S. Bardelli, E. Schinnerer, V. Smolcic +62
We investigate the properties and the environment of radio sources with optical counterpart from the combined VLA-COSMOS and zCOSMOS samples. The advantage of this sample is the av…
The VIMOS VLT Deep Survey: the group catalogue

[Abridged] We present a homogeneous and complete catalogue of optical groups identified in the purely flux limited (17.5<=I<=24.0) VIMOS-VLT Deep Survey (VVDS). We use mock catalog…
The faintest Seyfert radio cores revealed by VLBI
Marcello Giroletti, Francesca Panessa
In this letter, we report on dual-frequency European VLBI Network (EVN) observations of the faintest and least luminous radio cores in Seyfert nuclei, going to sub-mJy flux densiti…
