Welcome!

The 17th Gaia Science Alerts workshop and the ACME Time-Domain Workshop will take place in in Frejus, France, and online 31 Aug - 4 Sep 2026

The main topics:

  • Eleven Years of Gaia Science Alerts: overview of the Gaia Alerts system, statistics, major discoveries and scientific highlights.
  • Lessons Learned from Alerts from Space: operational experience from Gaia, alert detection pipelines
  • Future Space Transient Missions: SVOM, UltraSAT, PhotSAT, Einstein Probe, Roman Space Telescope, PLATO, Ariel.
  • Preparing for the LSST Era: alert stream, broker systems, alert filtering and coordination of follow-up observations.
  • Follow-up Infrastructure and Telescope Networks: robotic telescope networks, scheduling systems and coordinated follow-up of transient events across the globe.
  • BHTOM System: a platform for automated coordination of follow-up observations, data collection and management of time-domain observations
  • Citizen Science and Amateur Astronomy: contributions of amateur astronomers and small telescopes, observing campaigns through the EASST community.
  • Alert Brokers and Machine Learning: real-time alert processing, classification and filtering using machine learning techniques and broker systems.
  • Multi-Messenger Astronomy: optical counterparts of gravitational wave events, neutrino alerts and gamma-ray bursts, and the role of Gaia alerts in identifying and monitoring these sources.
  • Solar System Alerts: detection and follow-up of asteroids, comets and other moving objects, and the role of time-domain surveys in planetary defense and solar system science.
  • Rare and Exotic Transients: unusual and poorly understood phenomena such as tidal disruption events, luminous red novae and other rare classes of transients.
  • Legacy and Archival Science: long-term value of the Gaia Alerts dataset for variability studies, precursor activity of transients and training datasets for machine learning.
