Photometric redshifts are essential in studies of both galaxy evolution and cosmology, as
they enable analyses of objects too numerous or faint for spectroscopy. The Rubin
Observatory, Euclid, and Roman Space Telescope will soon provide a new generation of
imaging surveys with unprecedented area coverage, wavelength range, and depth. To take
full advantage of these data sets, further progress in photometric redshift methods is needed.
In this review, we focus on the greatest common challenges and prospects for improvement�…
