The Extragalactic Transient Universe

Marseille, France

6th-10th July 2026 

The 2026 edition of the GECO-LAM conference will discuss the “Extragalactic Transient Universe” at a time of great research opportunities favored by new facilities such the SVOM and Einstein Probe (EP) high-energy missions or the Vera Rubin Observatory, among multiple others. The conference will focus on diverse topics ranging from observations, theory and modeling of the broad population of astronomical transients, through multi-messenger astronomy, to the instrumentation, techniques and data management that are needed to make transient research successful.

Abstract submission opens on 12th of January 2026 and remains open until 27th February 2026. The programme will be published on April, 17th. Registration is already open and will stay open until May 1st. The meeting will be proposed in hybrid format.
