With the recent first light milestone for the Vera Rubin Observatory, it’s only a matter of time before one of astronomy’s most long-awaited surveys begins. The Legacy Survey of Space and Time (LSST) is set to start on November 5, and will scan the sky of billions of stars for at least ten years.

One of the most important things it aims to find is evidence (or lack thereof) of primordial black holes (PBHs), one of the primary candidates for dark matter. A new paper posted to the arXiv preprint server by researchers at Durham University and the University of New Mexico looks at the difficulties the LSST will have in finding those enigmatic objects, especially the statistical challenges, and how they might be overcome.
