The cosmological importance of radio galaxies - Dr. Steve Rawlings Colloquium

The Australia Telescope National Facility Colloquium
15:30-16:30 Wed 28 Apr 2004

ATNF Marsfield Lecture Theatre


Accreting black holes with weak or undetectable radio jets (radio-quiet
quasars) outnumber those with powerful jets
(radio-loud quasars) by a factors ~10-100, so
the influence of powerful-jet activity on galaxy formation
is often neglected. I will argue that the prodigious
kinetic power output of these radio-loud quasars (they are >100-times
more powerful than radio-quiet quasars) means that they
have a profound influence on the formation of massive galaxies, and hence
on cosmological models for the formation of structures in the Universe.
