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 galaxy evolution.
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&gt;~1.4). In the last few years we managed to collect observations from major facilities (HST, Spitzer, VLT, ALMA, MeerKAT, GMRT)&nbsp; on expressly designed, homogeneous, dedicated follow-up programs on this whole sample, for galaxy evolution studies as well as cluster characterization. We are now in the position to leverage these observations, together with additional new observations from our team of likely progenitor environments,&nbsp; 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. A significant component of the team developing and analysing semi-analytical models and hydro-dynamical simulations enables 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 only from INAF (Astrofisica Fondamentale 2022). 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.
