Tech Talks

Tech Talks is a forum to connect the Rubin LSST software community, showcasing work by the broad Rubin software and archives community designed to enable LSST science. We hope it will provide a forum for a range of groups and authors to present, learn about, and discuss efforts of interest to analysis of LSST data.

Tech Talks are delivered virtually every second Thursday of the month at 10:00 a.m. Pacific [1:00 p.m. ET, 3:00 p.m. Chile (November and onwards through winter), and 7:00 p.m. Central European Time]. You can access it via Zoom at The recordings are publicly available generally within a week of the talk. Want to receive future seminar announcements?

Upcoming Talks

  • Fink: enabling multi-messenger astronomy in the Rubin era by Emille Ishida

In this talk I will present Fink, an astronomy broker specifically designed for LSST. Fink is based on high-end technology and designed for fast and efficient analysis of big data streams. It has been chosen as one of the official LSST brokers who will receive the full data stream.  I will highlight the state-of-the-art machine learning techniques used to generate early classification scores for a variety of time-domain phenomena (kilonovae, supernovae, microlensing and solar system objects among others). I will also describe the development of personalized machine learning models which are able to deliver different streams based on user feedback and discuss the implementation and philosophical challenges involved.
