The small size of the SETI workforce is a major problem for NASA and the search for life elsewhere in the universe. The Astro2020 Decadal should address this issue by making nurturing the field an explicit priority for the next decade.

This white paper presents the case for SDSS-V. SDSS-V is an unprecedented all-sky spectroscopic survey of over six million objects. It is designed to decode the history of the Milky Way galaxy, trace the emergence of the chemical elements, reveal the inner workings of galaxies and their stars, and investigate the origin of planets.

Bars in galaxies are thought to stimulate both inflow of material and radial mixing along them. Observational evidence for this mixing has been inconclusive so far, however, limiting the evaluation of the impact of bars on galaxy evolution. We now use results from the MaNGA integral field spectroscopic survey to characterize radial stellar age and

The paper outlines research and development needed over the next decade to enable three-dimension mapping of the Universe using the 21 cm line of neutral hydrogen.

Considerable uncertainties remain about the nature of warm, AGN-driven outflows and their impact on the evolution of galaxies. This is because the outflows are often unresolved in ground-based observations. As part of a project to study the AGN outflows in some of the most rapidly evolving galaxies in the local Universe, here we present Hubble
