The Gamma-Ray Astronomy Database: 1990-2002 [PDF]

open access: yesSymposium - International Astronomical Union, 2003
I review five missions (SIGMA/GRANAT, the Compton Gamma-Ray Observatory, BeppoSAX, the Interplanetary Network, and the High Energy Transient Explorer) which have contributed to a golden age of discovery in gamma-ray astronomy. The data from many of these missions and experiments have been archived and are available to the public to analyze.

HEALPix Alchemy: Fast All-Sky Geometry and Image Arithmetic in a Relational Database for Multimessenger Astronomy Brokers

open access: yesThe Astronomical Journal, 2022
Abstract Efficient searches for electromagnetic counterparts to gravitational wave, high-energy neutrino, and gamma-ray burst events demand rapid processing of image arithmetic and geometry set operations in a database to cross-match galaxy catalogs, observation footprints, and all-sky images.

Kepler Bonus: Light Curves of Kepler Background Sources

open access: yesThe Astronomical Journal, 2023
NASA’s Kepler primary mission observed about 116 deg ^2 in the sky for 3.5 consecutive years to discover Earth-like exoplanets. This mission recorded pixel cutouts, known as target pixel files (TPFs), of over 200,000 targets that were selected to ...
