Summary

Story summary

ImageMM reduces atmospheric blur in ground-based telescope images, improving weak gravitational lensing measurements.
The algorithm was tested on the Subaru Telescope in Hawaii, producing sharper images.
It will next be applied to the Vera C. Rubin Observatory in Chile.
ImageMM adapts the Majorization–Minimization method for astronomical imaging.
Even with advances, Hubble Space Telescope and James Webb Space Telescope remain superior.
