Nachts auf der Sternwarte
The lecture series "Nights at the Observatory" presents an extensive program of lectures on a variety of topics on astrophysics. The lectures are accessible to the general public and are held in German or English (see program). After the talk there is a visit to the Great Refractor.
Cosmological dark matter from dwarf galaxies to galaxy clusters
In this talk I will discuss the problem of dark matter: why we seem to find it on all galactic scales, how we can infer it from measurements of the motions of stars and galaxies even though we cannot see it, and how it challenges our current (mis)understanding of gravity.
Priv.-Doz. MMag. Dr. Tanja Rindler-Daller
