Lasair is a broker for astronomers studying transient and variable astrophysical sources. It is being developed as a collaboration between the University of Edinburgh and Queen's University, Belfast to build a broker service for alerts generated by the Large Synoptic Survey Telescope (LSST). We are planning to serve LSST transient alerts to the LSST user community and combine these data with value-added cross-matches against existing catalogues and analysis tools.
To help prototype the functionality needed to process alerts from LSST, Lasair is currently ingesting and presenting alerts from the public stream of the Zwicky Transient Facility (ZTF), which is releasing a transient alert stream in a format similar to that envisaged for LSST. We thank ZTF for access to this valuable public data stream. Lasair provides a broker system for users to access, visualise and extract science data. The capabilities of Lasair will develop incrementally, guided by user feedback, so please try it and tell us what more you need to do your science -- use the Contact link.
