Summary. At a distance of 3.4 Mpc, NGC 5128 (Centaurus A) is by far the nearest active radio galaxy. It is often considered to be the prototype Fanaroff-Riley Class I ‘low-luminosity’ radio galaxy, and as such it plays an important role in our understanding of a major class of active galaxies. Its proximity has spawned numerous detailed investigations of its properties, yielding unrivalled but still incomplete knowledge of its structure and dynamics. The massive elliptical host galaxy is… 

ALMA Observations of the Physical and Chemical Conditions in Centaurus A

Centaurus A, with its gas-rich elliptical host galaxy, NGC 5128, is the nearest radio galaxy at a distance of 3.8 Mpc. Its proximity allows us to study the interaction among an active galactic

Abstract Centaurus A (NGC 5128) is ideal for investigating the characteristics and role of gas in an earlytype galaxy in the presence of a radio-loud active nucleus. The different phases of the

Unveiling the Active Nucleus of Centaurus A

We report new Hubble Space Telescope WFPC2 and NICMOS observations of the center of the nearest radio galaxy Centaurus A (NGC 5128) and discuss their implications for our understanding of the active

Discovery of a 500 Parsec Shell in the Nucleus of Centaurus A

Spitzer Space Telescope mid-infrared images of the radio galaxy Centaurus A reveal a shell-like, bipolar, structure 500 pc to the north and south of the nucleus. This shell is seen in 5.8, 8.0, and

The Leo Elliptical NGC 3379: A Metal-Poor Halo Emerges

We have used the ACS camera on HST to obtain (V, I) photometry for 5300 red giant stars in the halo of the dominant Leo group member NGC 3379, a galaxy usually regarded as a classic normal giant

Gemini Near Infrared Spectrograph Observations of the Central Supermassive Black Hole in Centaurus A

The Gemini Near Infrared Spectrograph on Gemini South unlocks new possibilities to study the central black holes (BHs) in dusty galaxies that have been inaccessible to previous BH studies. We exploit

Stellar populations in NGC 5128 with the VLT: Evidence for recent star formation

We resolve stars of the nearest giant elliptical galaxy NGC 5128 using VLT with FORS1 and ISAAC. We construct deep U , V and K s color-magnitude and color-color diagrams in two different halo fields

LABOCA observations of nearby, active galaxies

We present large scale 870 μm maps of the nearby starburst galaxies NGC 253 and NGC 4945 as well as the nearest giant elliptical radio galaxy Centaurus A (NGC 5128) obtained with the newly

Star formation efficiency along the radio jet in Centaurus A

Centaurus A is the most nearby powerful AGN, widely studied at all wavelengths. Molecular gas has been found in the halo at a distance of ~20 kpc from the galaxy centre, associated with HI shells.
