The Radio Continuum Properties of Centauraus A
Presenter: Ronald Ekers (CSIRO/ATNF)
Abstract: Centaurus A is a very special for radio astronomers: it heralded the discovery of the extragalactic radio source population. It is the brightest radio source in the southern sky, the closest radio galaxy, the closest AGN and probably the closest super massive blackhole. For a long time it was also the largest radio galaxy known. I will give an overview of the radio continuum morphology from the megaparsec scale of the outer lobes down through the middle lobe and the inner double straddling the galaxy and its dust lane to the sub pc scale structure of the AGN core and jet. Centaurus A was one of the first radio galaxies to be studied in detail but it is still full of surprises and its alternating symmetric and asymmetric structures confound our theories.
