... Programme . ... Abstract: Centaurus A is both the nearest radio galaxy and the nearest massive early-type galaxy, making it a unique astrophysical laboratory in which we can study the processes of these two classes of objects at a sensitivity unattainable in any other object. Centaurus A has been well studied by the current generation of high-energy observatories including Chandra, XMM-Newton, Suzaku, Galex, Swift, and Fermi. ...
