Black holes, gravitational waves & cohorts

Max Planck Institute for Gravitational Physics at the COSPAR Conference in Bremen

July 15, 2010

The 38th International COSPAR Conference (Committee on Space Research), the world’s biggest conference devoted to space research, will take place in Bremen from 18 -25 July 2010. Scientists from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) will give several talks there about the LISA space mission as well as other topics on gravitational wave research. In an exhibition, which will also be open to the general public, the AEI will also present an interactive satellite model of LISA, the Laser Interferometer Space Antenna. Location: Congress Centrum Bremen, Bürgerweide 1, 28215 Bremen

Gravitational waves are minuscule changes in space-time, which propagate at the speed of light. They are generated through extremely massive astrophysical processes and have to date not been detected directly through experiments. Earthbound gravitational wave detectors in the USA (LIGO), in Italy (Virgo) and in Germany (GEO600 in Ruthe near Hannover) are, however, hot on the heels of these “ripples in space-time”. In frequency ranges below 1 Hertz, gravitational waves though are only observable from space. From 2020, the space mission LISA (Laser Interferometer Space Antenna), a joint project between ESA and NASA, will search in these low frequency ranges for massive objects such as black holes and merging galactic centres.
