Probing the Interstellar Gas and Dust in Nearby and Distant Galaxies with the Hubble and James Webb Space Telescopes

Characterizing the properties of the gas and dust in the multi-phase interstellar medium (ISM) in galaxies is crucial for understanding the role of star formation and feedback processes in galaxy evolution. We will report results from our recent and ongoing Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS) observations for local galaxies (with redshifts z<0.1) that have been mapped with MaNGA integral field spectroscopy. These observations enable us to compare the properties of the gas in the halos of these galaxies with the gas in the inner regions of the galaxies. Specifically, we compare how the metallicity, ionization, and kinematics of the cool and warm gas in the halos of these galaxies (determined from the absorption lines in the spectra of the background quasars) compare to extrapolations of maps of the gas properties in the inner ~1.5-2.5 effective radii of the galaxies (from the MaNGA maps). Additionally, we will describe results on interstellar dust in galaxies at 0
