In the Lambda Cold Dark Matter (ΛCDM) framework, galaxies emerge at the centre of dark matter (DM) halos forming stars in a way connected to the growth of such halos. On the micro scale, supermassive black holes (SMBH) accrete gas and grow in close connection with the properties of their host galaxies (see e.g. the BH–galaxy/group scaling relations). Energetic processes within galaxies may impact their surroundings, at galactic and/or halo scales, influencing future gas accretion and star formation (SF). Feedback from radio-loud Active Galactic Nuclei (AGN), in particular, is often invoked to explain the observed properties of massive galaxies in the local Universe. The role of jet-induced feedback at higher redshifts (z ≳ 1) is less clear, as radio-AGN activity shifts towards lower-mass, mostly star-forming galaxies (SFG). Shedding light on the interplay between SMBHs, galaxies and DM halos requires observations over large cosmological volumes to probe all environments and include the rarest galaxy/AGN populations, while also being gas/dust insensitive to unveil the dominant contribution of obscured AGN and SF activity. Ongoing deep RC surveys, in combination with extensive multi-wavelength coverage, are providing an unprecedented view on the physical properties of radio AGN and SFG populations across cosmic time, in a dust/gas-unbiased manner. In this talk I will discuss some recent results obtained from LOFAR and MeerKAT deep fields and I will present ongoing work and future plans and perspectives.

Isabella Prandoni is Science Director at the Institute of Radio Astronomy of the National Institute for Astrophysics (INAF) in Bologna, Italy. Her research focuses on galaxy formation and evolution, with particular emphasis on the role of supermassive black holes in shaping galaxies across cosmic time. Her work combines radio interferometric techniques and deep extragalactic radio surveys to investigate the evolution of galaxies and active galactic nuclei. She holds leading roles in several major observational programs conducted with next-generation radio telescopes, including LOFAR, MeerKAT, and ASKAP. Dr. Prandoni coordinates national activities in preparation for the forthcoming SKA Observatory, and serves as a member of the Italian delegation to the SKAO Council.
