Gas around galaxies, the circumgalactic medium (CGM), contains crucial information about how gas accretion and galactic outflows drive galaxy evolution. While the properties of the CGM have been investigated via gas absorption lines imprinted in the spectra of background sources and direct detection of gas emission, these two methods are only sensitive to gas in certain phases and under specific physical conditions.
In this talk, I will discuss the potential of localized fast radio bursts (FRBs) as a new probe to uncover previously unexplored properties of the CGM. I will begin by providing an overview of our understanding of the CGM and then discuss how localized FRBs can help address key unanswered questions.
