UNDERSTANDING THE FANAROFF–RILEY RADIO GALAXY CLASSIFICATION

Gaia: Understanding the Galaxy

The GAIA Observatory, ESA's Cornerstone 6 mission, addresses the origin and evolution of our Galaxy, and a host of other scientific challenges. GAIA will provide unprecedented positional and radial velocity measurements with the accuracies needed to produce a stereoscopic and kinematic census of about one billion stars in our Galaxy and throughout the Local Group, about one per cent of the Gala...

The Microjansky Radio Galaxy Population

We use highly spectroscopically complete observations of the radio sources from the VLA 1.4 GHz survey of the Hubble Deep Field-North region to study the faint radio galaxy population and its evolution. The fraction of radio sources that can be optically spectroscopically identified is fairly independent of radio flux, with about 60−80% identified at all fluxes. We spectrally classify the sourc...

Galaxy Clusters in the Radio: Relativistic Plasma and ICM/Radio Galaxy Interaction Processes

Radio jet interactions in the radio galaxy PKS 2152 - 699

We present radio observations of the radio galaxy PKS 2152-699 obtained with the Australia Telescope Compact Array (ATCA). The much higher resolution and s/n of the new radio maps reveals the presence of a bright radio component about 10 arcsec NE of the nucleus. This lies close to the highly ionized cloud previously studied in the optical and here shown in a broadband red snapshot image with t...
