David E. Trilling, Michael Gowanlock, Revanth Munugala +5
The Solar System Notification Alert Processing System, SNAPS, is a downstream broker that ingests moving object data from ZTF and LSST and serves these data and derived properties…
Parallel R-tree-based Spatial Query Processing on a Commercial Processing-in-Memory System
Tasmia Jannat, Michael Gowanlock, Satish Puri
The growing volume of data in scientific domains has made spatial query processing increasingly challenging due to high data transfer costs across the memory hierarchy and limited…
Asteroid Period Solutions from Combined Dense and Sparse Photometry
Michael Gowanlock, David E. Trilling, Andrew McNeill +2
Deriving high quality lightcuves for asteroids and other periodic sources from survey data is challenging due to many factors, including the sparsely sampled observational record a…
