On July 15th, 2010, Pavel Kroupa held an invited colloquium on "Local Group galaxies as critical tests of the contemporary cosmological model and its failure" at the Helmholtz-Institut fuer Strahlen und Kernphysik of the University of Bonn. The venue had to be shifted to a larger lecture theatre.
The Bethe Center for Theoretical Physics invited Prof. Dr. Simon White (Max Planck Institue for Astrophysics, Garching) and on July 16th Pavel Kroupa (AIfA, Bonn) to hold the Bethe Colloquium on "Dark Matter: a debate".
It will take place on November 18th, 2010, at 3:15 pm, in Lecture Hall 1 of the Physikalisches Institut, Nussallee 12, 53115 Bonn. It is open for all interested. However, it is not likely to be easily accessible for the lay person. The abstract of the Nov.18th Bethe Colloquium reads:
"The subject of this months Bethe Colloquium concerns a question at the interface of cosmology, astrophysics and elementary particle physics: the possible existence of Dark Matter. The existence of Dark Matter is the most prominent proposal to account for the discrepancy between measurements of the mass of galaxies, clusters of galaxies and the entire universe, and measurements based on the mass of the visible matter. So far the existence of Dark Matter is inferred from gravitational effects on visible matter and background radiation and not through direct detection. In his talk Professor S. White introduces the dark matter paradigm and explains its virtues. An alternative proposal to explain the observed discrepancies is introduced by Professor P. Kroupa. He argues that these effects could be due to a modification of the laws of gravity without the need of Dark Matter. The talks are followed by a discussion."
The web-site of the Bethe Colloquia can be found here, and the poster advertising the debate is provided below. A higher resolution pdf version of the poster can be downloaded here. Uni-Bonn-TV will prepare a videopodcast of the event.
