Joint Survey Processing has been identified as a critical step for achieving robust cosmological and astrophysical results from next-generation surveys. Jointly analyzing pixel data from the Nancy Grace Roman Space telescope and the Vera C. Rubin Observatory will enhance the extraction of scientific information for a wide range of astrophysical and cosmological applications, e.g., weak lensing shape measurements and deblended photometric redshift estimations; dark matter and modified gravity constraints from detailed models of low-surface brightness galaxies; and transient host modeling with higher precision than attainable with forced photometry or difference imaging. This will improve the scientific returns of both the experiments.
