The Largest Catalogue to Date: AGN Outflows in Dwarf Galaxies
Dwarf galaxies have been historically thought to be regulated by winds from supernovae. However, in recent years, several studies have provided growing evidence for the presence of AGN outflows, and of possible AGN feedback, in dwarf galaxies. In this talk, we present a catalogue of 1242 dwarf galaxies with AGN outflows, the largest sample to date, drawn from DESI DR1 spectroscopy based on the detection of a broad component in the [OIII] emission line. We analyze the kinematic and energetic properties of these outflows, introducing a pioneering outflow velocity threshold to determine the ionization source. We find, based on the coupling efficiency and the capability of the outflow to escape the dark matter halo, that AGN feedback in dwarf galaxies may be as important as, or even more significant, than that in massive galaxies.
