GaiaAlerts2025 continues the series initiated in 2010 by members of the Gaia space mission, including scientists from the University of Cambridge and the University of Warsaw.

The 2025 workshop will celebrate the end of the Gaia space mission operations. It will also concentrate on time-domain archives and multimessenger observations as part of the new Horizon Europe grant ACME.   It will gather experts from time-domain astronomical surveys like Gaia, ZTF, OGLE, and LOFAR, alongside scientists analysing the data. For the first time, the workshop aims to unite researchers from various multimessenger fields, including optical, radio, X-ray, UV, gravitational waves, and neutrinos, providing a platform to discuss synergies and access extensive time-domain archives.
