HIGHLIGHT LECTURE 2

Gravitational Wave Detection on Ground and in Space – The New Window to The Universe

Wednesday 3 October 2018, 18:00 – 19:00
Location: Bremen Exhibition & Conference Center – DLR Hall

 

According to Einstein, gravitational waves are created by accelerated masses like in binary systems of Black Holes or Neutron Stars which circle around each other, approach each other, and finally merge. The gravitational wave signals carry information about the physics of the Black Holes, in particular of their event horizons, and of the highly extreme states of matter inside Neutron Stars. Such gravitational waves can also be used for a highly precise method to establish a cosmological distance scale which will contribute to a further independent and improved determination of the Hubble parameter and of the dark energy in our universe. Furthermore, gravitational waves can provide a better understanding of the fluctuations of matter and space-time in the very early universe and its inflationary phase. Beside electromagnetic radiation, gravitational waves thus provide a second and very clean way to observe the dynamics of Black Holes, stars, and the whole universe.

Professor for Theoretical Physics and Director for Space Sciences,

Center of Applied Space Technology and Microgravity (ZARM),

Germany

Full Bio

Prof. Dr. Claus Lämmerzahl studied physics at the University of Konstanz where he also made his Diploma and PhD, and also received his habilitation. During that time he also made a postdoc in Paris. After a further position at the Heinrich-Heine University Düsseldorf he moved to the Center of Applied Space Technology and Microgravity (ZARM) at the University of Bremen. He is Professor for theoretical physics and Director for Space Sciences at ZARM. His interest lies in gravitational theory, quantum theory, test of fundamental principles underlying gravity and quantum physics, but he is also PI of several experimental projects like MICROSCOPE, QUANTUS, RelaGal and others, all aimed for testing basic principles of General Relativity and quantum mechanics. He is member of the Mexican Academy of Sciences and of the International Academy of Astronautics.

 

SPEAKER

Karsten Danzmann

Director,

Max Planck Institute for Gravitational Physics (Albert Einstein Institute) and Institute for Gravitational Physics of the Leibniz Universität Hannover,

Germany

Full Bio

Prof. Dr. Karsten Danzmann is Director of the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) and Director of the Institute for Gravitational Physics of the Leibniz Universität Hannover. He studied physics in Clausthal-Zellernfeld and made the Diploma as well as his PhD at the Univeristy of Hannover. After his PhD he had research stays at Stanford University and at the PTB (Physikalisch-Technische Bundesanstalt) in Braunschweig. In the early 1990ies he became project leader for the gravitational wave interferometer GEO600 which was completed in 2005. At the GEO600 interferometer crucial technologies for the larger LIGO and VIRGO gravitational wave detectors have been developed what led to the detection of gravitational waves. K. Danzmann also proposed a space mission called LISA (Laser Interferometer Space Antenna) for the measurement of gravitational waves and is leader of this project on the European side. K. Danzmann has been awarded many very prestigious prices, among others the Max-Planck research price, the Körber European Science Prize, the Otto Hahn Prize, and the Stern-Gerlach Medal of the German Physical Society, and he is also member of a number of scientific academies. He is also speaker of various graduate schools indicating his great interest in the education of young people.
