Galaxy quenching with KILOGAS
Resolved spectroscopy of star-formation shutdown in nearby galaxies.
KILOGAS is an integral-field-spectroscopy (IFS) survey of ~500 nearby galaxies designed to capture the spatial signatures of star-formation quenching in nearby galaxies. The sample has sub-kiloparsec level optical IFS (MaNGA/SAMI) and ALMA data. Whereas my PhD focused on integrated properties of distant galaxies, KILOGAS lets me ask where in a galaxy the quenching first takes hold — the centre, the outskirts, or in patchy regions.
At ASIAA I’m working on combining KILOGAS spatially-resolved star-formation maps with structural information from imaging to ask whether a galaxy’s structural state predicts the spatial pattern of its quenching. The goal is to understand the links between structural features of galaxies and mode of quenching – star formation efficiency (SFE) vs. gas availability.
