Pavel Kroupa: On the Non-Existence of Dark Matter

Dr. Kroupa is a Czech-Australian astrophysicist, whose research interests focus on the dynamical properties and evolution of stellar systems, structure and mass of the galaxy, and the dark matter content of galaxies, among others. He presented the first stellar-dynamic computations of star clusters, in which all stars are born as binary systems. He is famous for the eponymous Kroupa initial mass function (IMF), which describes the distribution of stellar masses at their birth. In 2008, he pointed out that the intergrated-galactic IMF theory implies that disk galaxies have a radial star formation law. Since 2010, Dr. Kroupa is increasingly concerned with various aspects of cosmology. One of the implications of his work is that effective gravity must be non-Newtonian in the ultra-weak field limit, and that the observed structures on scales of dwarf galaxies and below are fundamentally inconsistent with the predictions of the standard cosmological model. In 2007, he was honored by a Swinburne University Visiting
