August-Issue of "Spektrum der Wissenschaft"

Current Issue of SdW with our Article on Dwarf and Satellite Galacies and the problems of Dark MatterThe new issue of Spektrum der Wissenschaft (SdW) is in the shops today. Our (Pavel Kroupa and Marcel Pawlowski) article on dwarf galaxies and dark matter is even mentioned on the cover and in the editorial. In Germany and Austria, you can buy the magazine for 7.40 Euros. Alternatively, you can download the free PDF of our article "Das kosmologische Standardmodell auf dem Prüfstand" from the SdW website and read it right away.

When SdW asked us to start this blog, we agreed. The main reason was to make a direct discussion about the issues we raise in the text possible. We will post additional texts (in English) on this blog, which might lead to interesting debates. In case you would like to comment on the article in SdW, feel free to give your statements or ask questions here.


Author: Marcel S. Pawlowski

I am a postdoc at the Department for Astronomy of Case Western Reserve University in Cleveland, OH (soon Hubble Fellow at UC Irvine). My work revolves around tidal dwarf galaxies – second-generation galaxies forming from the debris of galaxy collisions – and their use for testing models explaining the dark matter phenomenon. During my PhD studies in Bonn (in Pavel's group) my research concentrated on the phase-space distribution of the Milky Way's satellites (dwarf galaxies, globular clusters and tidal streams), their possible formation scenarios (in particular tidal dwarf galaxies) and tests of cosmological models on (cosmologically) small scales. My research interests are complemented by my interest in the philosophy of science and in science outreach.
