Title: Spatially-resolved, ionized gas kinematics: a WIYN follow-up for SDSS- MaNGA
Abstract: Turbulent-driving scenarios are largely constrained by the relationship between SFR, gas velocity dispersion, and gas fraction. I propose to observe six nearby, face-on disk galaxies to obtain precise measurements of gas velocity dispersion. In combination with SFRs and gas fractions obtained from fitting nebular emission in SDSS/MaNGA galaxies, the high-resolution (~17 km/s) gas kinematics will serve to constrain the source of turbulence in the ISM, investigate whether a mixture of drivers is an appropriate model, whether there is a critical SFR above which feedback dominates, and examine variations across environments, morphologies, and location within galaxies.
