<b>Abstract:</b> Galaxies are intimately connected to the environments they live in. The haloes around them contain the gas reservoir from which the galaxies grow, while galactic outflows heat and enrich this circumgalactic medium (CGM). Understanding the CGM
can thus help us constrain models of galaxy formation. Using zoom-in cosmological simulations of galaxies, I will discuss the physical properties of the gas around galaxies. The multiphase nature of the CGM is affected by the resolution of our simulations,
which enhances the amount of cool, neutral gas in the halo, bringing them more in line with observations. I will show how the properties of galaxies and the CGM depend on the presence of magnetic fields, on feedback from relativistic cosmic rays, and on the
inclusion of thermal conduction. I will also discuss how and why dwarf galaxies and massive galaxies are affected differently by these processes. </div>
