The Universe evolves over very long timescales — billions of years — so it’s tempting to think that it is a rather gentle place. But it is also host to some violence goings-on, events that release vast amounts of energy over very short timescales — years, months, or even minutes. In this talk I will look at how we detect these high-energy phenomena and outline some of the Universe’s most exotic participants, from the kilonovae that made my wedding ring to the supermassive black holes that dominate entire galaxies.
