Questo programma studia galassie di ammasso in un campione di cinque ammassi piu' distanti identificati dalla Sunyaev-Zel'dovich Survey del South Pole Telescope (SPT-SZ), tra i sistemi più massivi conosciuti a questo redshift (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.
Il progetto corrente è basato prevalentemente su osservazioni ottiche/NIR dei telescopi Hubble, Spitzer, VLT per misurare effetti ambientali su storia di formazione stellare, 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.
This program studies galaxy populations in a sample of 5 most distant clusters identified in the South Pole Telescope Sunyaev-Zel'dovich Survey (SPT-SZ), among the most massive systems known at this redshift (log(M200/Msun)>14.6). This is currently the only statistical, homogeneous cluster sample deemed to be representative of the general population of galaxy clusters at these masses and redshift.
The current project is largely based on optical/NIR observations from Hubble, Spitzer and VLT telescopes, aimed at probing environmental signatures on stellar populations, 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 clusters 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). In the last few years we managed to collect observations from major facilities (HST, Spitzer, VLT, ALMA) 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, 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>
