Supernova Exchange 2.0: Software for Follow-up of Extragalactic Transients in the Rubin Era

Описание: Craig Pellegrino presents "Supernova Exchange 2.0: Software for the follow-up of extragalactic transients in the Rubin era" in this LINCC Tech Talk that took place on Thursday, February 8, 2024. Co-hosts are Colin Orion Chandler (LINCC Frameworks, DiRAC Institute, University of Washington) and Mi Dai (LINCC Frameworks, University of Pittsburg).

Abstract: Rubin’s LSST will revolutionize time-domain astronomy by expanding our search for astronomical transients to fainter magnitudes and higher redshifts. With roughly a million alerts expected to be issued to the time-domain community each night, it will be increasingly paramount to develop software infrastructure to identify and prioritize the most scientifically interesting targets. Identifying and rapidly following many types of transients, including supernovae and gravitational wave event counterparts, in turn, is vital to maximizing their scientific impact. Software to meet these needs entails automated filtering, ingestion, and follow-up observation submission of these targets in a customizable manner to suit the scientific interests of different time-domain subfields. Here I will present the Supernova Exchange 2.0 (SNEx2), a Target and Observation Manager (TOM) with wide-ranging applications within time-domain and multi-messenger astronomy. TOM software automatically ingests time-domain targets from alert-stream brokers and other sources, displays photometric and spectroscopic data, and allows for follow-up observation submission on a growing set of queue-scheduled and robotic telescopes. SNEx2 is written to enable this functionality while remaining broadly applicable; it is open-source and easily customizable to address specific scientific objectives within time-domain astronomy. I will detail the unique features of SNEx2, including its interface with telescope resources such as the Las Cumbres Observatory telescope network, its user-driven alert-stream broker filters, and its capabilities in the search for electromagnetic counterparts to gravitational wave detections. Finally, I will discuss ongoing efforts to prepare SNEx2 for the Rubin era using the Rubin Science Platform and Data Preview 0 data products.
