In Fontanot et al. 2025, we present model prediction from the latest version of the GAEA model coupled with merger trees extracted from the P-Millennium Simulation. We present, for the first time, GAEA predictions for the 2-point galaxy correlation function, and compare with available data in the redshift range 0<z<3. We show that our model reproduces nicely the main dependencies of the 2pCG as a function of stellar mass, star formation activity, HI content and redshift for galaxies with stellar mass <10^11 M⊙. Our work shows that the latest GAEA version captures correctly both the distribution of galaxies in the large-scale structure and the interplay between the main physical processes regulating the baryonic content of dark matter haloes.

In Cammelli et al. 2025, we study the growth of supermassive black holes from PopIII.1 seeds coupling our GAEA model with dark matter merger trees generated using the PINOCCHIO algorithm. The approach allows us to access the resolution necessary to resolve the minihaloes in which PopIII stars form. We present predictions for the properties of galaxy populations, and discuss implications for the PopIII.1 seeding mechanism. 

Lagos et al. 2025 presents a detailed study of the star formation histories of high-z massive quiescent galaxies from recently published theoretical models (including GAEA). The study discusses how the disparate predictions obtained from independent models can be tied to the adopted AGN feedback, and are testable with current facilities and upcoming observations.   

In Scharré et al. 2024 we combine our GAEA model with advanced photoionisation models and use results to make emission-line predictions at 0.4<z<2.5. We validate our methodology against observational and theoretical data at low-z and forecast the fraction of line-emitting galaxies that Euclid will observe at different cosmic epochs. Using our model results, we propose novel redshift-invariant tracers for the black hole accretion rate-to star formation rate ratio. Finally, we find that commonly used metallicity estimators display a gradual shifts in normalization with increasing redshift, in tentative agreement with recent JWST measurements.
