A new benchmark for the local and high-z scaling relations of

supermassive black holes: Dissecting the roles of AGN feedback and

black hole mergers

The correlations between Supermassive Black Hole (SMBH)

mass and host galaxy properties can reveal the processes

shaping the coevolution of SMBHs and galaxies, from mergers

to Active Galactic Nuclei (AGN) feedback. However, a clear

knowledge of the exact shape and evolution of these relations

is still missing. In this talk, I will present the latest results on

the SMBH scaling relations, their residuals, and their time

evolution. I will conclude by presenting a cutting-edge

comprehensive semi-empirical/data-driven model for the

evolution of SMBHs in a cosmological context, inclusive of

mergers and accretion rates in line with observed Eddington

ratio distribution, starting from the high-z conditions imposed

by luminous red dots to the local Universe.
