Transregional Collaborative Research Centre TRR 33 - The Dark Universe

Universität Heidelberg jointly with Universität Bonn and LMU München

Second Funding Period 7/2010-2011-2012-2013-6/2014


In the standard cosmological model, normal baryonic matter contributes only roughly 5% to the overall density of our universe, the rest being in the form of dark matter (27%) and dark energy (68%). Whereas dark matter has already been postulated by Zwicky in 1933, the existence and dominance of dark energy was unexpected and raised fundamental questions such as the range of validity of Einstein's gravity, the role of extra dimensions, the existence of new forces, the nature of vacuum, the relation to the inflationary field and to the particle physics models.

Our transregional research center 'The Dark Universe' investigates these topics by means of theoretical approaches, observations, and numerical simulations.

An overview of the 18 different projects within the transregio is on the projects page. (Projects of the 1st funding period are described there in the archiv). Project Groups and Project leaders are listed here.

The state of the field, and of the Collaborative Research Center TRR33 has been monitored concisely at the 2011 Heidelberg meeting

The 2011 Nobel Prize in Physics has been awarded "For the discovery of the accelerating expansion of the Universe through observations of distant supernovae", and here are the 2013 results of the Planck Mission.

The TRR33/3 application for the third funding period 7/2014 - 6/2018 has been reviewed December 2013 at Bonn University. An overview talk of the 18 renewed and new projects is at Transregio33_overview
