This awarded program (ASTRO15F-0121) is to understand two major aspects of how the gaseous halo of galaxies depends on the interplay from models of star formation--feedback loop and the galactic environment. We aim to study the CGM by combining approaches from cosmological galaxy simulations and UV spectroscopy in observations. Absorption spectroscopy of background QSOs provides a powerful probe for studying the complex baryonic cycles in galactic halos that are otherwise invisible. Commonly seen absorption features of the low-redshift circumgalactic medium (CGM) occur in the UV spectral regime, which are only accessible in space. The Cosmic Origins Spectrograph on board the Hubble Space Telescope has offered a unique opportunity to advance the field of CGM studies. The proposed research will combine UV QSO absorption spectra obtained using COS and the state-of-the-art cosmological zoom-in simulations to gain deeper understandings of the origin and evolution of chemically enriched gas ...
