Kinematics of parsec-scale structures in AGN: the 2cm VLBA Survey
E. Ros, K. I. Kellermann, M. L. Lister +5
We are investigating the kinematics of jets in active galactic nuclei on parsec scales by studying a representative population of sources. This study is being carried out using the…
Associated HI in Absorbers at High Redshift
R. C. Vermeulen
WSRT observations have provided a first inventory of the incidence of HI 21 cm line absorption associated with AGN at redshifts up to z=1.0. There is a large range in line depths,…
HI gas disks in elliptical galaxies
E. M. Sadler, T. Oosterloo, R. Morganti
We discuss a class of low-luminosity E/S0 galaxies which have both HI disks and (in contrast to more luminous E/S0s with HI) ongoing star formation. We suggest that such objects ar…
HI absorption and the ISM around radio galaxies
R. Morganti, T. A. Oosterloo, C. N. Tadhunter +3
We present a study, done with the Australian LBA, of HI absorption for two compact radio galaxies (PKS 1549-79 and PKS 1814-63). In both the radio galaxies, the HI appears to give…
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…
Extremely Red Galaxies
Paola Andreani, Andrea Cimatti, Huub Roettgering +1
Preliminary results of a project aiming at unveiling the nature of the extremely red galaxies (ERGs) (objects with colours R-K>6 and I-K>5) found in deep optical-NIR surveys are pr…
