Selection and characterisation of Red Geysers in the MaNGA survey

Red Geysers are quiescent galaxies that show a bi-polar outflow, but the mechanism that produces this outflow is still unclear. Using MaNGA data, we find that Red Geysers correspond to ∼1.6% of the sample of galaxies already observed by MaNGA. About ∼16% of the Red Geysers show clear evidence of Active Galactic Nuclei, as revealed by emission-line ratios.
