The physics that drives galaxy evolution operates on a large dynamic range of spatial scales and across a wide range of gas phases. The unique perspective enabled by high-resolution radio continuum, polarimetric, and spectral line observations offers important insights not possible in other parts of the electromagnetic spectrum. I will present several examples of this, where SKA precursors/pathfin ... More

Radio galaxies (RGs) are active galactic nuclei (AGN) able to launch relativistic jets, the most energetic phenomena in the Universe, which can have a large impact on galaxy evolution. Current high-sensitivity and high-resolution surveys have shed new light on properties of RGs, particularly in the local Universe (z<0.3) and at low luminosities (<10^24 W/Hz a 1.4 GHz), where the bulk of the AGN po ...

The evolutionary stage of a powerful radio source originated by an AGN is thought to be related to its linear size. However, the fraction of young radio sources in flux density-limited samples is much larger than what is expected from the number counts of large radio sources, suggesting the existence of short-lived objects and/or intermittency of jet activity. Determining the incidence of young bu ... More

The advent of new generation radio telescopes is opening new possibilities on the classification and study of extragalactic high-energy sources, specially the underrepresented ones like radio galaxies. Among these, Giant Radio Galaxies (GRG, larger than 0.7 Mpc) are among the most extreme mani- festations of the accretion/ ejection processes on supermassive black holes. Our recent studies have sho ... More

The high angular resolution and sensitivity of VLBI offers a unique tool to identify and study AGN and star-formation activity over cosmic time. VLBI observations are crucial for identifying young radio sources and unveiling older restarted radio sources. Also, radio imaging over a large range of angular scales is needed to determine the role of black hole feedback and jet-induced star formation i ... More
