Studio di galassie di ammasso in un campione di 5 ammassi piu' distanti identificati nella South Pole Telescope Sunyaev-Zel'dovich Survey, tra i sistemi più massivi conosciuti a z>~1.4 (log(M200/Msun)>14.6). Questo e' correntemente l'unico campione statistico omogeneo ritenuto rappresentativo della popolazione generale di ammassi a queste masse e redshift, con un follow-up specifico per studi di evoluzione delle galassie. Il progetto corrente è basato su osservazioni ottiche/NIR da Hubble, Spitzer, VLT, e radio da MeerKAT e GMRT, per misurare effetti ambientali su formazione stellare e quenching, crescita in massa stellare e proprietà strutturali delle galassie d'ammasso, per la prima volta in maniera consistente e omogenea su un campione rappresentativo di questi sistemi estremi a z~1.5.
A galaxy population study in a sample of 5 most distant clusters identified in the South Pole Telescope Sunyaev-Zel'dovich Survey, among the most massive systems known at z>~1.4 (log(M200/Msun)>14.6). This is currently the only statistical, homogeneous, representative cluster sample at these masses and redshift with a specific follow-up for galaxy population studies.
The current project is based on optical/NIR observations from Hubble, Spitzer and VLT, and radio continuum from MeerKAT and GMRT, aimed at probing stellar populations, star formation and quenching, structural properties and stellar mass assembly of massive cluster galaxies, for a first-time consistent, homogeneous analysis in an unbiased, representative sample of such extreme environments at this redshift.

<p>The cluster sample studied in this project in currently the only statistical, representative, galaxy-unbiased sample of very massive, most distant clusters (z>~1.4) with an extensive, homogeneous follow-up that we gathered in the last few years with major facilities (HST, Spitzer, VLT, ALMA, MeerKAT, GMRT), expressly designed for galaxy evolution studies as well as for cluster characterization. We are now in the position to leverage these observations, together with additional new data from our team in likely progenitor environments, for a combined investigation of the evolution of galaxy populations within the first, massive clusters emerging from the density field right after the crucial transition time between the proto-cluster and cluster regimes. An important component of the team is involved in the development and analysis of semi-analytical models and hydro-dynamical simulations, enabling a proper, consistent interpretation of these observations within the cosmological framework as well as in the context of literature results. <br></p>

21. Fondi a Sostegno Iniziativa
Since the PI joined INAF (2020) this project has received funding from INAF (Astrofisica Fondamentale 2022) with a GO grant devoted to the exploitation of VLT FORS2 and HAWK-I observations. An INAF mini-grant obtained by Maurilio Pannella in 2023 was also partly linked to this project, being focused on the data treatment (reduction and analysis) of MeerKAT and GMRT radio continuum data obtained on the clusters studied in this project. In its earlier phases, this project had been previously funded in Germany (LMU Muenchen, 2016-2019) by grants from DFG and DLR. Here below we only mention research funding obtained since this project became active within INAF.
