Fitting SPS models to IFU spectra and HST aperture photometry data: towards spatially resolved dust attenuation law within Galaxy NGC3583

We present an updated analysis of the spatial variance of the dust attenuation law within galaxy NGC 3583. We utilize Stellar Population Synthesis (SPS) fitting on the resolved integral field unit (IFU) spectra provided by the MaNGA survey in SDSS DR17, in conjunction with aperture photometry from SDSS and HST images. The addition of photometry provides significant improvement from our previous iteration, allowing us to constrain the metallicity and dust attenuation separately. We revisit our methods for fitting IFU spectra data for the dust law (including preparation of the localized spectra data with an adaptive blurring), and we discuss our results and their scientific implications, as we cross-check the fit with two independent pipelines, BAGPIPES and Prospector. Finally, we analyze how the inclusion of photometry in our fitting compares with the fitting of just spectra alone.
