Café & Kosmos 9 July 2013
The invisible scaffold that supports the Universe
5 juli 2013
With Dr Jörg Dietrich (Universitäts-Sternwarte der Ludwig-Maximilians-Universität)
Astronomers believe that all the matter we know of, in the whole Universe, has been accumulating on an invisible scaffold made of dark matter over the history of the Cosmos. Stars and galaxies have formed over billions of years on the invisible threads of this network. Attracted by the nodes of the scaffold, they have clumped together to form galaxy clusters and superclusters.
However, until now, the dark matter has escaped direct observation. All we know about the structure of this invisible scaffold is through the distribution of the ordinary matter that we can see and measure.
An international research group from Observatory of the Ludwig-Maximilians University has recently succeeded, for the first time, in detecting a thread of this invisible cosmic scaffold between the adjacent clusters of galaxies Abell 222 and Abell 223.
Dr. Jörg Dietrich, the leader of the team which made that discovery, will share his new insights into the cosmic scaffold with the participants at the next Cafe & Kosmos.
Cafe & Kosmos is back to its previous venue, at Vereinsheim, Occamstr. 8, in Munich. Note that Café & Kosmos events take place in German.
