Welcome to the homepage of the Hamburg Observatory!
Here you can find some information on research and teaching at the Hamburg Observatory as an institute of the Physics Department of the University of Hamburg as well as on the history, the historical architectural design, the equipment and the big range of events and services for the public.
We wish an expedient and entertainig reading. In case you need any further information we will be pleased to help.
Massive stars with at least eight times the mass of our sun end their lives in a violent supernova explosion. During this event, a huge amount of mass, energy and momentum is injected into the ambient medium. Hence the stellar remnant interacts with its parental molecular cloud - the places of ongoing star formation. Recently, researchers from the Hamburger Sternwarte, in collaboration with researchers from Cologne and Morelia (Mexico), have analysed the influence of the stellar death on the evolution of their parental molecular cloud by means of 3D numerical simulations (B. Körtgen, R. Banerjee, et al. http://arxiv.org/abs/1603.09593). These simulations followed the formation of the molecular clouds from the beginning of star...
