Spatially resolving properties of galaxies across cosmic time with piXedfit

Currently, most photometric studies of galaxies have only been done by treating a galaxy as a single point object or modeling them with a few axisymmetric components. The advent of IFU surveys has revolutionized the way we study galaxies. Despite its powerful capabilities, wide-area IFU surveys are only limited to local galaxies. The latest development in the spectral energy distribution (SED) fitting method makes it possible to implement the method on a pixel-to-pixel basis. piXedfit, pixelized SED fitting, is a python package that provides tools for obtaining spatially resolved stellar population properties of galaxies from multi-band imaging data. This package will be an essential tool for studying the stellar population properties of galaxies across a wide redshift range in the era of big data in photometry (from JWST, WFIRST, LSST, and Euclid).
