Simulation-based inference of galaxy properties from JWST pixels

Published in Astronomy & Astrophysics, 2025

We present an efficient Bayesian SED-fitting framework for multiwavelength pixel photometry from JWST/JADES using simulation-based inference. The pipeline produces spatially resolved maps of stellar population properties for 1083 galaxies and ~2 million pixels. We assess the outshining phenomenon and find limited impact except in low-mass galaxies.
