Discovery of a pseudobulge galaxy launching powerful relativistic jets
  Supermassive black holes launching plasma jets at close to speed of light,
producing gamma-rays, have ubiquitously been found to be hosted by massive
elliptical galaxies. Since elliptical galaxies are generally believed to be
built through galaxy mergers, active galactic nuclei (AGN) launching
relativistic jets are associated to the latest stages of galaxy evolution. We
have discovered a pseudo-bulge morphology in the host galaxy of the gamma-ray
AGN PKS 2004-447. This is the first gamma-ray emitter radio loud AGN found to
be launched from a system where both black hole and host galaxy have been
actively growing via secular processes. This is evidence for an alternative
black hole-galaxy co-evolutionary path to develop powerful relativistic jets
that is not merger-driven.
