Goal: to localise and classify Fermi LAT point sources, infer source properties

  • The second step done in unsupervised way leaving space to detect new source classes
  • comparison with traditional methods, i.e. catalogs relatively ‘straightforward’

Status: we started with the classification first

  • Generated data that have ‘AGN-like’ and “PSR-like’ sources, whole sky, in 4 energy bins
  • Shared data + simple notebook with the challenge participants (via slack channel)
  • Had constructive discussions & first results

Next steps: — add diffuse model and focus on localisation — probabilistic programming (started by Christoph, revamp?), to study source properties Status: we started with the classification first

  • Meeting today (+these days?) in Lunquist to agree on this plan and discuss details
