A view of the sub-mJy populations, modelling and perspectives for future deep surveys
I. Prandoni, P. Parma, A. Mignano +5
We use deep multi-colour (UBVRIJK) images mostly taken in the framework of the ESO Deep Public Survey (DPS) to optically identify and derive photometric redshifts for a complete sa…
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…
