The diffuse, multiphase gas surrounding galaxies, known as the circumgalactic medium (CGM), has emerged as a key player in regulating gas accretion, star formation and feedback processes. Recent advances in observational techniques, including absorption-line studies and high-resolution emission mapping using deep integral field spectroscopy, have enabled the CGM to be probed with unprecedented detail across cosmic time. The first international conference in Chile dedicated to the CGM was held in the scenic rural town of Santa Cruz, in the Colchagua Valley. Hosted under the clear southern skies and surrounded by vineyards, the workshop brought together around 80 researchers from 12 countries, uniting observers and theorists to explore the rapidly advancing understanding of the CGM and its pivotal role in galaxy evolution.
