Talk Title |
Testing MOND with Milky Way globular clusters |
|
Abstract |
The dark matter paradigm and cold dark matter (CDM) cosmology are widely accepted theories on which much of our understanding of the properties and evolution of the Universe is based. Yet these paradigms face a number of serious problems. A heuristic alternative to dark matter is the theory of modified Newtonian dynamics (MOND) and its relativistic formulation TeVeS. It has been shown that MOND fits the rotation curves of galaxies remarkably well, so additional tests are desirable in order to understand if the dynamics of the Universe on large scales is dominated by dark matter or MOND/TeVeS. In my talk I will report first results from a new test of MOND by measuring internal velocity dispersions and stellar mass functions of globular clusters in the outer halo of the Milky Way. |
