Modeling the faint radio population: the nanoJy radio sky
I. Prandoni, H. R. de Ruiter, P. Parma
The apparent change in the composition of the parent optical objects of radio sources around 1 mJy (at 1.4 GHz) is now well established, although there is still some debate about t…
Dying Radio Galaxies In Clusters
M. Murgia, P. Parma, H. R. de Ruiter +2
We report the recent discovery of three `dying' radio galaxies belonging to the WENSS minisurvey sample: WNB1734+6407, WNB1829+6911 and WNB1851+5707. These sources have been select…
The Nature of the Faint Radio Population
I. Prandoni, L. Gregorini, P. Parma +4
We present the results obtained so far from the optical follow-up of the ATESP sub-mJy radio survey. The ATESP results are then compared with the ones obtained from other deep radi…
HI absorption from the central kpc of radio galaxies: effect of orientation or interstellar medium?
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +6
We present a summary of recent studies of HI absorption in radio galaxies. The results show how the absorption can be due to a variety of phenomena and how they can help us in unde…
HST images of B2 radio galaxies: the link between circum-nuclear dust and radio properties
H. R. de Ruiter, P. Parma, R. Fanti +2
We discuss HST images in V and I of radio galaxies selected from the B2 sample of low luminosity radio galaxies. Absorption maps were constructed which highlight the presence of ci…
The HST snapshot survey of the B2 sample of low luminosity radio-galaxies: a picture gallery
A. Capetti, H. R. de Ruiter, R. Fanti +3
A Hubble Space Telescope snapshot survey of the B2 sample of low luminosity radio galaxies has, at present, produced V and I images of 41 objects. Together with 16 images of B2 sou…
