FIRST ANNOUNCEMENT - DECEMBER 2025

It is our pleasure to announce the “Extragalactic Transient Universe” conference, which will take place in Marseille (France) from 6 to 10 July 2026. This meeting is the latest in the conference series organised by the GECO (Galaxies, Stars, and Cosmology) group at the Laboratoire d’Astrophysique de Marseille.

The study of the transient Universe is experiencing a golden age, driven by the development of new facilities and advanced observational techniques. Exceptional scientific opportunities are emerging thanks to instruments such as the SVOM and Einstein Probe (EP) high-energy missions, the Vera Rubin Observatory, and many others.

The conference will focus on a wide range of topics, from observations, theory, and modelling of the diverse population of astronomical transients, to multi-messenger astronomy, as well as the instrumentation, techniques, and data-management approaches required to advance transient science.

The goal is to explore the common ground shared by different transient phenomena—whether in observational strategies, the underlying physical processes, the progenitor systems that lead to transients, or the influence of the host-galaxy environment.

 

Research topics to be discussed at the conference will include:
·    Gamma-Ray Bursts
·    Fast Blue Optical Transients
·    Core-collapse supernovae
·    Tidal Disruption Events
·    Fast Radio Bursts
·    Exotic transients
·    Multi-messenger observations
·    Theory and simulations
·    Massive stars as progenitors
·    Host galaxies
·    Instrumentation, surveys, and observational techniques

Important dates:
12 January 2026 - Abstract submission and registration opens
27 February 2026 - Abstract submission deadline
17 April 2026 - Programme release
1 May - Registration closes
