Abstract

The last decade has opened up a new parameter space in time-domain astronomy with the discovery of extragalactic transients defying our understanding of how stars explode. Some of those represent the brightest event of the transient zoo – called superluminous supernova – while many others show different degrees of interactions with the material expelled before the death of the star. The collected dataset and the understanding of such events have surpassed any initial expectations and opened up a future exploding with potential, spanning from novel tools of high-redshift cosmological investigation to new insights into the final stages of massive stars.

Join me in this seminar as we embark on a retrospective journey, exploring the unforeseen dimensions of these cosmic phenomena. Be ready for a sneak peek into the cosmic theatre, where the stage is set for the next decade’s astronomical wonders. Discover how these observations could reshape our understanding of stellar explosions and connected research areas.
