New (and old) ideas on dark matter — •Bjoern Malte Schaefer — Heidelberg University

Dark matter is an essential concept in modern cosmology and is indispensable if Newtonian gravity is extrapolated to scales of galaxies and larger. In my talk I will review the necessity of dark matter and its role in cosmic structure formation and galaxy evolution, and discuss possible particle candidates, in particular axionic dark matter as a possible solution to outstanding dark matter problems in cosmology.
