Peering Through the Space Between Stars and Galaxies

Most of the ordinary matter in the universe that is not locked up in stars takes the form of diffuse ionized gas, or plasma. The distribution of this ionized gas through cosmic time is critical to galaxy evolution, which is driven by interactions between the dark matter halos where galaxies form and the gas that seeds star formation, shaping the rich diversity of galaxies observed today. In this talk I will discuss recent breakthroughs in our efforts to resolve the distribution of cosmic plasma across a vast range of spatial scales, from nearby interstellar space traversed by the Voyager Interstellar Mission, to space between galaxies traversed by fast radio bursts. Over the next decade, upcoming missions and surveys will continue to transform our observational understanding of cosmic plasma and its role in galaxy evolution, yielding an abundance of opportunity for the next generation of astronomers.
