Today's colloquium: Studying Fundamental Physics with Radio Astronomy (M. Kramer , Bonn)

Submitter: Jean-Mathias Griessmeier
Description: Radio astronomical measurements allow the study of a variety of questions in fundamental physics. Those questions range from the equation-of-state of super-dense matter to the investigation of fundamental forces such as gravity and magnetism. This talk will focus mostly on the exploitation of fast-rotating neutrons stars that are visible as radio pulsars. Their observations allow us to test general relativity and alternative theories of gravity and works towards the detection of a long-wave cosmological gravitational wave background. The current status and future experiments are discussed.
