GAEA (GAlaxy Evolution and Assembly) e’ un modello teorico 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 all'interno della comunita' astronomica e usato in numerosi 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 theoretical 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.

21. Fondi a Sostegno Iniziativa

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 - 750k€); the MERAC foundation (funded one postdoctoral position - 146k€); INAF (funded two PhD fellowships one of which was interrupted by the student for personal reasons - about 80k€). 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. The project has received funds from INAF in the form of a Theory Grant (grant assigned in 2022). The budget allocated (50k€) has been included in the numbers given in this section. As anticipated in the theory grant proposal, the entire budget was allocated to hire one postdoctoral fellow that has now been included as a team member, and who started on September 2023. In 2023, we were granted funding (one 2-year postdoctoral position) for a project focused on the exploitation of SKA and its precursors. The postdoc selection has been completed and the hired AdR should start in September. We have not included this funding to the numbers below as the project is only partially based on GAEA.
