GAEA (GAlaxy Evolution and Assembly) e’ un modello semi-analitico di ultima generazione che segue la storia della formazione stellare e della metallicità delle galassie e dell’accrescimento del gas su buchi neri massicci in volumi cosmologici. Il modello, sviluppato negli scorsi anni da un gruppo internazionale di ricerca con un nucleo basato a Trieste, e’ rinomato a livello internazionale e usato in diversi progetti con diversi obiettivi. Il buon accordo tra le predizioni del modello e diverse stime osservative a diverse epoche cosmiche, fanno di GAEA uno strumento utile e moderno per (i) interpretare i dati in un contesto cosmologico; (ii) testare/validare procedure di analisi dati; (iii) guidare la concezione e definizione di futuri programmi e strategie osservative.
GAEA (GAlaxy Evolution and Assembly) is a state-of-the-art semi-analytic model that follows the star formation, metallicity and black hole accretion history of galaxies in cosmological volumes. The model, developed over the past years by an international group of researchers with a core team based in Trieste, is well renowned by the astronomical community at large and is being used in a number of different projects with different goals. In fact, the good agreement between predictions from our model and a wealth of observational measurements at different cosmic epochs, makes GAEA a useful and timely tool to (i) interpret data in a cosmological framework; (ii) test/validate data analysis procedures; (iii) guide the conception and design of future observational programmes and strategies.

<p style="text-align: justify; ">While GAEA does not represent the only theoretical model available to the INAF community, it is characterized by a unique level of sophistication, and includes detailed and tested prescriptions to account for physical processes that are typically neglected in similar models (e.g. non instantaneous recycling approximation, variable stellar initial mass function, H2-to-HI transition). GAEA is <span style="font-family: var(--bs-font-sans-serif); font-size: 1rem;">internationally renowned and among the most successful models published in the past years. </span></p><p style="text-align: justify; "><span style="font-family: var(--bs-font-sans-serif); font-size: 1rem;">The</span><span style="font-family: var(--bs-font-sans-serif); font-size: 1rem;"> widespread use of GAEA within several collaborations, despite being built around a relatively small number of people, demonstrates the strong interest by INAF researchers. As to our knowledge, GAEA is mentioned - because explicitly used or planned to be used - in about 20 independent programmes, some of which are based on very large international collaborations (VANDELS, MOONS-VLT-0, EuclM2, SKA). A complete list of the programmes (to our knowledge) that mention GAEA or explicitly include team members is given in box 13 (Linee di ricerca).</span></p>

The major past funding sources for this programme have been: European Research Council (StGDeLucia - funded TD and then TI position for De Lucia for five years, one PhD fellowships and two 4-year postdoctoral position); the MERAC foundation (funded one postdoctoral position); INAF (funded two PhD fellowships one of which was interrupted by the student for personal reasons). In the estimate given below, we have considered only 2/3 of the ERC grant to account for the fact that it was not entirely dedicated to GAEA developments/projects. At the time of writing, the project does not have specific funding.
