Understanding Gas Flows in-and-around Galaxies

The circumgalactic medium is a multiphase halo surrounding individual galaxies that significantly influence galaxy formation and evolution. The direct observation of the CGM is challenging due to the diffuse nature of CGM gas, resulting in limited observational evidence for accretion and outflows. This thesis demonstrates the complex and multiphase nature of the CGM, and reveals the kinematic behaviour of the multiphase CGM gas flows and their host galaxies. It emphasizes the importance of conducting statistical analysis on various CGM ions to unveil the intricate connection between galaxies and their circumgalactic halo.
