Abstract
- Centaurus A (NGC5128) is a fantastic object, ideal for investigating the characteristics and the role of the gas in an early-type galaxy in the presence of a radio-loud active nucleus. The different phases of the gas - hot (X-ray), warm (ionised) and cold (HI and molecular) - are all detected in this object and can be studied, due to its proximity, at very high spatial resolution. This richness makes Centaurus A truly unique. Spatially, these gas structures span from the pc to the tens of kpc scale. Thus, they allow us to trace very different phenomena, from the formation and evolution of the host galaxy, to the interplay between nuclear activity and ISM and the feeding mechanism of the central black hole. A lot of work has been done to study and understand the characteristics of the gas in this complex object and here I summarise what has been achieved so far.<br />Accepted for publication in PASA, review presented at the conference "The Many Faces of Centaurus A", Sydney 2009, 12 pages
