Abstract: Understanding how galaxies evolve over cosmic time requires knowledge of not only integrated galaxy properties but also spatially resolved structures within galaxies. The IFS surveys have been revolutionizing the study of galaxy evolution. However, due to the expensive nature of this observation, wide-area IFS surveys have been limited to observing local galaxies. On the other hand, high spatial resolution and deep imaging surveys enable us to resolve substructures in galaxies over a wide range of redshift. Furthermore, recent advancements in the SED fitting method have opened up avenues for spatially resolved analysis of galaxies using Imaging data. In this talk, I will first introduce our novel method of pixelized SED fitting (piXedfit; for analyzing spatially resolved spectrophotometric SEDs of galaxies. Then I will discuss some works that we have been doing using this tool on analyzing spatially resolved properties of galaxies across a wide redshift range (0<z<7). We have been applying our method to imaging (and IFU) data from various surveys, including recent JWST NIRCam and simulated data of Euclid and LSST.
