This month, we are joined by the Kernel-based Moving Object Detection team, including Jeremy Kubica (LINCC, CMU), Max West (LINCC,UW), Wilson Beebe (LINCC,UW), Drew Oldag (LINCC,UW), and Dino Bektešević (UW), and co-host Colin Orion Chandler (UW) who will talk about one of the core projects from LINCC Frameworks. This talk is part of the LINCC Tech Talks series, hosted by Colin Orion Chandler (DiRAC Institute, University of Washington) and Mi Dai (University of Pittsburg), and takes place every second Thursday at 10:00 AM Pacific time. More information about the Tech Talk series is available here: lsstdiscoveryalliance.org/programs/tech-talks/
This talk was held on Thursday, December 12, 2024.
Abstract:
Shift and stack algorithms have the potential to push down into the noise and find distant solar system objects that are too faint to detect with traditional linkage algorithms. In this talk we present KBMOD, a shift and stack algorithm designed to find Trans-Neptunian Objects (TNOs). We introduce the core algorithm which was originally applied to fields of the DEEP survey. We then discuss recent extensions led by a joint team from LINCC Frameworks and the University of Washington to improve the robustness and accuracy of the algorithm. Specifically we discuss how we can account for nonlinear motion due to the Earth’s own orbit in order to make the tracking more robust across nights.
