Calibration of hybrid resolved star formation rate recipes based on PHANGS-MUSE H$\alpha$ and H$\beta$ maps

Mapping star-formation rates (SFR) within galaxies is key to unveiling their assembly and evolution. Calibrations exist for computing SFR from a combination of ultraviolet infrared bands as integrated systems, but applicability sub-galactic (kpc) scales remains largely untested. Here we use integral field spectroscopy 19 nearby ($D <$ 20 Mpc) obtained by PHANGS-MUSE derive accurate Balmer decrements (H$\alpha$/H$\beta$) attenuation-corrected H$\alpha$ maps. We combine this information with mid-infrared maps WISE at 22 $\rm \mu m$, GALEX in the far-UV band, surface densities on resolved scales. Using reference, find that hybrid recipes literature overestimate regions low density, specific rate (sSFR), attenuation old stellar ages. attribute these trends heating dust populations (IR cirrus). calibrate effect proposing functional forms coefficients front IR term which depend band ratios sensitive sSFR. These calibrations prove reliable function physical scale. In particular, they agree 10% corrections computed decrement 100 pc Despite small quantitative differences, our are also applicable galaxy probed MaNGA survey, albeit larger scatter (up 0.22 dex). Observations JWST open up possibility relations cloud-scale ($\sim$100 pc) resolution mid-IR imaging.
