ML for galaxy types in SDSS and WISE


This easy WebService allows you to quickly view the status of galaxies in a field. It will request WISE and SDSS databases, do a quick cross-match, and apply a machine learning algorithm based on Bonjean et al., (2019) to estimate the SFR and stellar mass of galaxies, up to z=0.3. You will find interactive plots, and you can select your galaxies per type, by drawing your selection with your mouse directly on the SFR/stellar mass plot.
