The 2026 edition of the GECO-LAM conference discusses 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 focuses 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.

The meeting takes place in a hybrid format. The conference counts with invited talks, contributed talks, and posters. Fees are 450 EUR (full), 250 EUR (PhD students) and 50 EUR (online).
