Abstract
There is a consensus that feedback processes likely play a vital role in the evolution of dwarf galaxies, given their shallow potential well. While stellar processes have long been considered the primary source of feedback, it is still debated whether such stellar feedback is effective enough to reproduce the properties of dwarf galaxies we see today. Given the increasing number of AGN detected in dwarf galaxies, and the tentative evidence of AGN feedback in them as reported by recent literature, it is crucial to evaluate the impact of AGN feedback in dwarf galaxies. In this talk, I will present our studies of the AGN feedback in dwarf galaxies by observing the fast outflows in a sample of nearby dwarf galaxies with AGN through optical integral field spectroscopy and far-ultraviolet spectroscopy. These outflows are faster than those observed in star-forming galaxies with similar stellar mass and star formation rates. They are mainly photoionized by the AGN, and a small but non-negligible portion of them may escape the galaxies. They are primarily AGN-driven and may have an impact on their host galaxies similar to those taking place in the more luminous AGN.
