Indexing and Fast Near-Matching of Billions of Astronomical Objects
Any type of content formally published in an academic journal, usually following a peer-review process.
When astronomers analyze sky images, they need to identify the newly observed celestial objects in the catalog of known objects. We have developed a technique for indexing catalogs, which supports fast retrieval of closely matching catalog objects for every object in new images. It allows processing of a sky image in less than a second, and it scales to catalogs with billions of objects.
