LSST Interdisciplinary Network for Collaboration and Computing

Tech Talks

A Forum to Connect the Rubin Software Community

Delivered virtually every second Thursday of the month at 10am Pacific (1pm ET, 1pm Chile, 7pm CET) these talks and demos will showcase work done by the broad Rubin software and archives community that’s 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.

Upcoming talks


  • June 08, 2023: Moving object image searches: a case study for metadata models (Stephen Gwyn)

The Solar System Object Image Search (SSOIS) at the Canadian Astronomy Data Centre (CADC) allows users to find images of their favorite moving object. SSOIS scrapes metadata from the archives of telescopes around the world and ingests them into a simple metadata system. At search time, a user can specify a solar system object's ephemeris either by object name, or by giving orbital elements, or by explicitly uploading a time series of positions. SSOIS then returns a list of images, with links back to the original telescope archive. The CADC also operates a much more intricate and comprehensive metadata system, the Common Archive Observation Model (CAOM). CAOM captures all the relevant information about an astronomical observation, be it a spectrum, an image or a data cube in a hierarchical metadata format. I will describe both SSOIS and CAOM, and contrast what drives the design of both metadata systems.

  • July 13, 2023: Pitt-Google Broker (Michael Wood-Vasey, Troy Raen, Chris Hernandez) 

  • August, 2023:  No talk, overlap with Project and Community Workshop
