Beschreibung

The discovery of the accelerated cosmic expansion has been awarded the Physics Nobel Prize 2011. It resulted in a remarkable additional component in the models of the Universe. Dark Energy, the term now commonly used for this unknown energy fraction represents a strange form of gravity, which is repulsive. Supernova observations have played a fundamental role in establishing the existence of Dark Energy and still are amongst the main tools to describe its characteristics. The most urgent question is whether the equation of state parameter (w) of the unknown component is variable or indeed Einstein's cosmological constant. With ma ny large supernova surveys coming to an end it is time to assess the current status and the promises for the future.
