Abstract: Unraveling the evolutionary paths of galaxies remains a key focus in astronomy. Over the past decade, the circumgalactic medium (CGM) has been recognised as a pivotal component in this research, serving as a record keeper of the processes of accretion and outflows, which move gas to and from the interstellar medium. In this talk, I will explore the CGM properties of galaxies, linking these properties to their stellar properties and using simulations to guide the interpretation of the observational findings.
