CLUSTER2


A view from Italy on galaxy clusters in the 21st century

Naples, 2018 September 10-13

Following the previous meeting CLUSTER1 held in Torino in 2017, the whole Italian community interested and working on galaxy clusters & groups organizes its 2nd national meeting to gather together, share ideas and discuss common projects.

GOALS:

  • to map the current situation within the national community of the ongoing research activities on galaxy clusters & groups, deemed both as cosmological probes and astrophysical laboratories, and studied through either theoretical models, numerical simulations, or 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 on how the Italian community is involved in major international collaborations.

We expect to cover a large variety of topics, including: the physics of the intracluster medium and of the feedback processes; the importance of clusters for cosmological studies; numerical simulations; theoretical models; weak and strong lensing; Sunyaev-Zeldovich effect; and multi-wavelength observations from radio to X-ray.

The talks should be focused on the role of the Italian community involved in the study of the galaxy clusters & groups science, as part of national projects as well as international ones. Abstract aiming at presenting the current status and the latest results on "local" projects, and the state-of-art of research activity of italian groups involved in international collaboration are welcome.

The meeting format will also include a half-day open discussion on the key questions that can be addressed in the near future on galaxy clusters & groups.
