Optimal Probabilistic Catalogue Matching for Radio Sources
Dongwei Fan, Tamás Budavári, Ray P. Norris +1
Cross-matching catalogues from radio surveys to catalogues of sources at other wavelengths is extremely hard, because radio sources are often extended, often consist of several spa…
Robust Registration of Astronomy Catalogs with Applications to the Hubble Space Telescope
Fan Tian, Tamás Budavári, Amitabh Basu +2
Astrometric calibration of images with a small field of view is often inferior to the internal accuracy of the source detections due to the small number of accessible guide stars.…
Galaxy Redshifts from Discrete Optimization of Correlation Functions
Benjamin C. G. Lee, Tamás Budavári, Amitabh Basu +1
We propose a new method of constraining the redshifts of individual extragalactic sources based on celestial coordinates and their ensemble statistics. Techniques from integer line…
Matching Radio Catalogs with Realistic Geometry: Application to SWIRE and ATLAS
Dongwei Fan, Tamás Budavári, Ray P. Norris +1
Crossmatching catalogs at different wavelengths is a difficult problem in astronomy, especially when the objects are not point-like. At radio wavelengths an object can have several…
Efficient Catalog Matching with Dropout Detection
Dongwei Fan, Tamás Budavári, Alexander S. Szalay +2
Not only source catalogs are extracted from astronomy observations. Their sky coverage is always carefully recorded and used in statistical analyses, such as correlation and lumino…
