I am a Czech-born Australian citizen teaching and researching at the University of Bonn on dynamics and stellar populations. After studying physics at The University of Western Australia, Perth, I obtained my PhD from Cambridge University, UK, as an Isaac Newton Scholar at Trinity College. After spending eight years in Heidelberg I habilitated at the University of Kiel, Germany. I then took up a Heisenberg Fellowship and later accepted the position as a professor at Bonn University in 2004. I was awarded a Leverhulme Trust Visiting Professorship (2007, Sheffield, UK) and a Swinburne Visiting Professorship (2007, Melbourne, Australia). My web-page: http://www.astro.uni-bonn.de/~pavel/
Pure innovative science can only truly thrive in non-hierarchical societies in which competition for resources is not extreme. Therefore I see the need for the German academic system to modernise (away from its hierarchies) and warn of academic systems that are based on an extreme competition for resources (USA), as these stifle the experimentation with new ideas.

Background: As introduced in the previous contribution to The Dark Matter Crisis, Question A: Galaxies do not work in LCDM, sociology and majority views, PK was recently contacted by a few people, and here are excerpts from some of the questions asked and the replies. These help to illustrate some of the issues at hand. The questions are A) So the LCDM model fails on scales smaller than about 8 Mpc? B1) What is a galaxy? B2) What is a galaxy?... Read more

Question B1: "What is a galaxy? - vote here!" Answer: The astronomical object we commonly call a "galaxy" has no formal definition yet. This issue is now raised to a more formal problem by Forbes & Kroupa (2011)(F&K). Here is the associated press release. Science and New Scientist also report on this question. Your vote is of interest: Being motivated by the vote at the General Assembly of the International Astronomical Union in Prague in the year 2006 on... Read more

Independently of any dark-matter detections or the success or failure of dark-matter searches (it is notable that the originally favoured dark matter particles have long ago been excluded through direct searches, as summarised by Prof. Stacy McGaugh), it is a well known problem that galaxies cannot be reproduced in the standard cosmological (i.e. the LCDM) scenario. In the LCDM model, the mass of the universe consists to about 4 % out of normal (baryonic) matter which we observe, while 96%... Read more
