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.

  1. Compact radio galaxies: the case of FR0s

    astro-ph.GA 2026-06 unverdicted novelty 3.0 of 10

    FR0 radio galaxies are abundant compact sources whose small sizes challenge standard evolutionary models, and SKA observations are expected to clarify their jet physics and demographics.
