CLUSTER3

A view from Italy

on galaxy clusters & groups

in the 21st century

Bologna, 20-23 September 2022

Aula Giorgio Prodi, Piazza San Giovanni in Monte 2

Following the previous meetings CLUSTER1 (Torino, 2017) and CLUSTER2 (Napoli, 2018), the Italian community interested and working on galaxy clusters & groups organizes its 3rd national meeting to gather together, share ideas, and discuss common projects.

We expect to cover a large variety of topics with the following goals:

to map ongoing research activities on galaxy clusters & groups, both as cosmological probes and astrophysical laboratories, and studied through theoretical models, numerical simulations, multi-band observations;
to share ideas on the fundamental questions that these research activities aim at solving, and we feel more urgent;
to get an overview of how the Italian community is involved in major international collaborations.

The talks should focus on the role of the Italian community involved in the science with galaxy clusters & groups, as part of national projects as well as international ones. Abstracts aiming to present the current status and the latest results on "local" projects (possibly in an aggregated form from each research group), and the research activity of Italian groups involved in international collaborations are welcome.

The meeting format will also include some round-tables for open discussion on the key questions that can be addressed in the near future on/with galaxy clusters & groups.
