Gaia Alerts 2025 and ACME Time-domain workshop announcement
Lukasz Wyrzykowski
Dear Colleagues,
The 16th Gaia Science Alerts and ACME Time-Domain Workshop will be held at the IACtec in La Laguna, Tenerife, Spain and online: 29th Sep - 3rd Oct 2025.
Workshop webpage and registration: https://meetings.iac.es/gaiaalerts25/
We encourage in-person participation, but a hybrid option will also be available.
Topics:
Celebrate the conclusion of the Gaia mission and Gaia Alerts
Science highlights from the Gaia mission
Science highlights from the Gaia Alerts
Science highlights and tutorials on the BHTOM follow-up system for a global telescope network
Transient surveys, ground-based, space-based, past and future
Time-domain astronomy (from supernovae and quasars to stars and asteroids)
The wealth of the time-domain multi-messenger archives
Synergies between optical telescope networks and multi-messenger facilities
New members of the BHTOM telescope network
Organization of the follow-up
Research and educational opportunities for small and mid-sized telescopes
Scope of the workshop:
Time-domain astronomy has recently emerged as a cornerstone of modern astrophysics, enabling the discovery and detailed study of transient and variable phenomena across the Universe. From stellar explosions to tidal disruption events, from gravitational wave counterparts to active galactic nuclei variability, time-domain data provide novel insight into the complex astrophysical processes. However, to fully harness the scientific potential of this emerging field, it is critical to integrate observations from across the electromagnetic spectrum and beyond, incorporating gravitational waves, neutrinos, and other messengers.
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 multi-messenger 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 multi-messenger fields, including optical, radio, X-ray, UV, gravitational waves, and neutrinos, providing a platform to discuss synergies and access extensive time-domain archives.
The workshop will also focus on the global telescope network BHTOM.space. This unique infrastructure, currently supported by the Horizon Europe ACME grant, is designed to coordinate follow-up observations of time-domain events with a global network of small and medium-sized telescopes, including ones in the Canaries. The workshop will facilitate discussions among telescope directors, operators, and users, address operational challenges, and explore new opportunities for integrating with multi-messenger alerts.

The conference fee (including lunches and coffee breaks for the first four days, Monday through Thursday, a trip to Teide Observatory, and a conference dinner) is €150 for the first 60 participants, thanks to a special budget covering a part of the costs, and €300 for additional participants. For a certain number of participants, the fee can be entirely waived upon a justified request sent by email to the WOC chair Łukasz Wyrzykowski (l...@astrouw.edu.pl) before the early bird deadline. Limited travel and hotel lodging support is available and can be applied the same way via email to the WOC chair.
