Extending SOMPZ beyond Spectroscopic Coverage for Roman Weak Lensing
Precision weak lensing cosmology requires accurate galaxy redshift distributions. However, the spectroscopic samples used to characterize these distributions do not fully span the magnitude--color--redshift space of weak lensing source galaxies, necessitating extrapolation. This challenge will be critical at the depth...
