Over the past decades, the study of highly energetic transient phenomena has led to several scientific breakthroughs from the discovery of r-process nucleosynthesis production sites to the first credible identification of ultra-high-energy cosmic-ray accelerators. In a general manner, these explosive events allow us to study extreme physical regimes (extreme gravity, extreme magnetic fields, relativistic shocks) and are unique probes to study the Universe properties up to high redshift. In the last 10 years, an unprecedented amount of new generation instruments observing the sky at all wavelengths and with all astrophysical messengers have significantly contributed to enlarging our vision of the transient sky phenomena. This observational revolution initiated by the gravitational wave interferometers has forced the astrophysical community to rapidly adapt to the new challenges of multi-messenger astronomy. In June 2024, the French community will have a leading role in this young research domain with a strong implication for the French lab. in the upcoming SVOM mission. In this seminar, I will review some of the latest results obtained by the scientific community exploring the high-energy transient sky, especially with a focus on the sources of interest for the SVOM mission. I will show how important will be the SVOM mission contribution to this exciting field of research that has probably revealed only a subset of its richness.
