Description
Since their spectacular first detection in 2015, gravitational waves have been at the forefront of observational physics, and have opened up the era of multi-messenger astronomy in which sources are studied by electromagnetic, neutrino, and gravitational wave emissions. Indeed, the wealth of astrophysical data gathered in the years since, is helping answer many open questions in the areas of astrophysics, black hole physics, fundamental theory, and cosmology.
In this talk I will give a general how gravitational wave observations are used to study such matters, and then make a selection of these topics to review in more quantitative detail. In particular, I will explain the possibility to do temperature measurements of black holes and magnetic fields by gravitational wave observations, as key examples of ongoing research done with students at Maastricht University.
