Extreme-Astrophysics in an Ever-Changing Universe

Since ancient times, astronomers’ attention has been drawn to changes in the sky. Today we know that most phenomena observed in “time-domain” astronomy are related to extreme astrophysical events or processes. Whether it is the explosion of stars in supernovae or the observations of flare stars, pulsars, gamma-ray bursts, blazars or active galactic nuclei, time-domain astronomy stretches across the whole electromagnetic spectrum and beyond. With increasing technical capabilities, the 21st century will see corresponding new instruments being developed or coming online, revolutionising our view of the ever-changing Universe.This conference will connect the observations from the past with those from the present and future. Providing a forum to discuss the various signals and sources, the conference will also celebrate the career of Prof. John Seiradakis, who has contributed to many aspects across the field.

Our ambition is to bring together different research communities and provide a platform for an exchange of ideas, experience and methods that may prove invaluable in promoting the unification, if possible, time-domain astronomy and approach them qualitatively similarly as probes of very different scale physics in which different effects become dominant at different systems. The discussions will cover not only the sources to be observed but also the instruments to be used and the physics to be derived.
