Researchers have developed a new method called LUTRA (Linear Undersampled Transients & Addition) to improve the processing of undersampled astronomical images. This technique optimizes the co-addition and background subtraction of images, which are often non-optimal in current methods, leading to reduced sensitivity and increased false alarms. LUTRA offers improved performance, enabling easier photometry and astrometry while providing super-resolution results. Demonstrations on Zwicky Transient Facility data show a 1.25x higher signal-to-noise ratio compared to existing techniques, and an open-source Python implementation is available. AI
