Star formation quenching in low-redshift galaxies

The way in which the star formation of galaxies get shut down is a key, but still open question in the field of galaxy formation. SDSS and high-z deep imaging data have shown that processes that quench a central galaxy are primarily those internal to the galaxy such as AGN feedback and morphological quenching. For satellite galaxies, however, quenching is primarily driven by external processes occurring within their host groups/clusters such as ram-pressure stripping and tidal stripping. I will talk about our recent studies on this topic, for both central galaxies and satellite galaxies in the SDSS sample, as well as insights from the MaNGA prototype data.
