Why it matters
Space telescopes like Euclid offer incredible clarity but can only see a small part of the sky, while ground telescopes see everything through a blurry atmosphere. This system 'bridges' the two, allowing astronomers to generate space-quality images of cosmic regions that have never been photographed from orbit.
From the abstract
The upcoming decade of observational cosmology will be shaped by large sky surveys, such as the ground-based LSST at the Vera C. Rubin Observatory and the space-based Euclid mission. While they promise an unprecedented view of the Universe across depth, resolution, and wavelength, their differences in observational modality, sky coverage, point-spread function, and scanning cadence make joint analysis beneficial, but also challenging. To facilitate joint analysis, we introduce A(stronomical)S(ur
