Black holes are among the most astonishing predictions of Einstein’s theory of gravitation. For the existence of these objects, which has long been questioned, there is now convincing evidence from observations from orbits of stars in the center of our Milky Way, from gravitational waves of merging ultracompact objects, as well as from the observed shadow of the supermassive Black Hole in M87. Both the theoretical prediction and the observation of black holes were awarded the Nobel Prize in Physics of the Year 2020.
The proposed School is dedicated to the observational, theoretical and also epistemological aspects of Black Hole physics and will cover the following topics: tentative definition of a Black Hole, observational evidence and possible alternative explanations for Black Holes, formation of Black Holes, global structure and causality of Black Hole spacetimes, rigorous definition of a Black Hole, singularity theorems, uniqueness of Black Hole solutions (no-hair theorems), stability properties, Black Holes in generalised theories of gravity, modelling Black Holes in analog-gravity models, quantum fields in Black Hole-spacetimes, Black Holes in quantum gravity proper, epistemological and philosophical aspects of Black Holes.

This school is aimed at doctoral students and postdoctoral researchers. Contributed posters of the participants are welcome.
