AlFoCS + Fornax3D: resolved star formation in the Fornax cluster with ALMA and MUSE

We combine data from ALMA and MUSE to study the resolved (∼300 pc scale) star formation relation (star formation rate vs. molecular gas surface density) in cluster galaxies. Our sample consists of 9 Fornax cluster galaxies, including spirals, ellipticals, and dwarfs, covering a stellar mass range of ∼ 108.8 −1011 M. CO(1-0) and extinction corrected Hα were used as tracers for the molecular gas mass and star formation rate, respectively. We compare our results with Kennicutt (1998) and Bigiel et al. (2008). Furthermore, we create depletion time maps to reveal small-scale variations in individual galaxies. We explore these further in FCC290, using the ‘uncertainty principle for star formation’ (Kruijssen & Longmore 2014a) to estimate molecular cloud lifetimes, which we find to be short ( 10 higher in its tail than in its stellar body
