Hitting the bullseye: studying the culprit of quenching SF in transitioning galax-

ies.
ABSTRACT:
The Shocked Poststarburst Galaxy Survey (SPOGS) is designed to catch galaxies during the crucial phase of star formation quenching. During this rapid transition, AGN are expected to actively expel a galaxy's molecular gas causing a move from the blue cloud to the red sequence. Recent observations of local galaxies in this transitional phase have begun to address outstanding questions associated with the quenching process, but as yet the duty cycle of this phenomenon and the range of properties present during the transition phase are poorly constrained. We propose to use the exceptional sensitivity of Arecibo to detect outflows via HI and OH absorption in twelve SPOGS systems. This study is intended to be a pilot study to validate the criteria used to search for molecular outflows during the starburst quenching phase and to begin a systematic search for and study of the impact AGN have on the molecular gas that fuels star formation prior to quenching.
