The 52nd "Saas-Fee Advanced Course" of the Swiss Society for Astrophysics and Astronomy (SSAA) will be held from 19 to 24 March 2023 in Les Diablerets, in the Swiss Alps. This course is primarily targeted at Ph.D. and advanced M.Sc. students, but can also be valuable to young postdoctoral researchers who would like to start exploring the field.  The "Saas-Fee Advanced Course" has taken place annually since 1971 and in 2023 it will be devoted to

The Circum-Galactic Medium across cosmic time : an observational and modeling challenge


19-24 March 2023, Les Diablerets (Switzerland)

The circumgalactic medium (CGM) is a fundamental component for the formation and evolution of galaxies. It acts as an interface between the galaxies and the larger structures of the Universe. As such, it is a crucial region to study because it is where we expect the gas exchanges -- regulating the star formation activity and thus the galaxy growth -- to take place. Historically, the CGM has been mainly studied through the absorption that it imprints in the spectra of background sources. Large surveys revealed evidences that gas is present around galaxies at large radii and that the CGM is a multi-phase medium with a complex structure, ionizing state and kinematics. The advent of integral field unit (IFU) instruments has revolutionized the study of the CGM by allowing their direct mapping in emission opening a new window on the CGM studies. Within this context of successful large observational surveys, like MUSE-GTO and COS-HALO, the forthcoming large facilities, such as the James Webb Space Telescope, and the substantial recent progress in improving numerical simulations and theoretical models, this is an extremely timely topic. The course will aim to give to young researchers a comprehensive view of the current state of the CGM studies both observational and theoretical by including a series of lectures by three distinguished lecturers. The program will be provided at a later stage.
 
Formal lectures will be complemented by interactive hands-on sessions, where the participants will have the opportunity to get their hands on observational and simulation data.  A several-hour-long afternoon break is scheduled, when the participants are encouraged to do winter sports or simply interact with each other.
 

Due to logistical aspects, the number of participants will be limited to 70 people. The school will be in-person only.

The registration is now closed.
