Title: Milky-Way Disk-Halo Interface: A Warm-Hot Mess!

Abstract: The disk-halo interface of the Milky Way is the region where the newly ejected material from the disk meets the preexisting halo gas. It is a layer of gas within the first 5-10 kpc of the Galaxy plane supported by the galactic fountains. The disk-halo interface plays a key role in the gas recycling and metal enrichment of the halo gas. The gas dynamics in this region regulate the overall extension and ionization condition of the disk-halo interface. In this talk, I will present new observational results of the extension of the warm-hot phase and the ionization state of the disk-halo interface of the Milky Way.

Title: Taking a Big Look at the Small Scale Circumgalactic Medium

Abstract: Galaxies are surrounded by a diffuse halo of gas known as the circumgalactic medium (CGM), which plays an important role in regulating their life cycle. CGM studies are mostly limited to absorption line techniques, which typically provide a single measurement per galaxy, making the full dynamics and scales of the CGM difficult to capture. Here I will show how gravitationally lensed quasar systems can be used to obtain multiple measurements for the CGM of a single galaxy, providing spatial information in the CGM of galaxies beyond the local universe. I will present how the properties of the cool CGM gas can vary on small scales and discuss some early interpretations of these results.
