Abstract: Low-mass galaxies (M* < 9.5 M☉) in our local universe provide a unique window into the formation and evolution of galaxies in the early universe. This allows us to understand how processes like star formation and the presence of black holes influence the growth of galaxies. While stellar feedback has long been seen as the primary driver of several low-mass galaxy properties, recent discoveries of active black holes (AGN) and AGN-driven outflows in low-mass galaxies challenge this view. In this talk, I will present our results from Keck/KCWI and JWST/NIRSpec observations, which show that AGN-driven outflows in low-mass galaxies are faster and more powerful than stellar-driven ones. We also detect numerous near-infrared coronal lines in low-mass galaxies with AGN and explore the kinematics of the coronal lines. Given the potential significance of AGN in low-mass galaxies, we identify improved techniques to detect AGN in these systems. Our WISE and Keck/NIRES results indicate that MIR variability is a promising method for uncovering AGN activity in low-mass galaxies, which could reveal a larger population of active black holes with masses below 106 M☉ in the universe.
