QHSC: The Quasar Candidate Catalog for the Hyper Suprime-Cam Subaru Strategic Program
The Astrophysical Journal Supplement SeriesThe Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) is a deep wide-field multiband imaging survey consisting of three layers (Wide, Deep, and UltraDeep), with the Wide layer covering ∼1470 deg ^2 to a depth of i ∼ 26 mag.

Advanced Weights for IXPE Polarization Analysis
The Astrophysical JournalAs the Imaging X-ray Polarimetry Explorer (IXPE) measures increasingly faint sources, the need for precise polarimetry extraction becomes paramount. In addition to previously described neural-net weights, we introduce here point-spread function weights ...

Gamma-Ray Burst Detection with Poisson-FOCuS and Other Trigger Algorithms
The Astrophysical JournalWe describe how a novel online change-point detection algorithm, called Poisson-FOCuS, can be used to optimally detect gamma-ray bursts within the computational constraints imposed by miniaturized satellites such as the upcoming HERMES-Pathfinder ...

Information-theory-based System-level Babcock–Leighton Flux Transport Model–Data Comparisons
The Astrophysical Journal LettersSystem-level Babcock–Leighton flux transport model–data comparisons are performed using information theory. The model is run with a maximum meridional flow speed of 16.5 m s ^−1 with the flow speed systematically varied by 20% (BLFT20) and 50% (BLFT50 ...
