The Supernova Exchange 2.0: Facilitating Scientific and Software Advances in the Rubin Era

I will present the Supernova Exchange 2.0 (SNEx2), a Target and Observation Manager (TOM) with wide-ranging applications within supernova research and multi-messenger astronomy. Using TOM software to programmatically filter targets of interest is paramount to optimizing the scientific results from surveys such as Rubin LSST. SNEx2 is written with this goal in mind while remaining broadly applicable; it is open-source and easily customizable in order to address specific scientific objectives within the field of time-domain astronomy. I will detail the unique features of SNEx2, including its implementation within the robotically-controlled Las Cumbres Observatory telescope network, its interaction with community alert-stream brokers, and its use in the search for gravitational wave counterparts. Finally, I will conclude by discussing the scientific results made possible by SNEx2, such as understanding the diversity in the progenitors and powering mechanisms of fast-evolving supernovae, during the Rubin era.
