In this model, a smaller and a large black hole move linearly towards each other and collide head-on. The smaller black hole moves faster, has a high downward momentum and emits strong gravitational waves downwards.
LISA Pathfinder was a test mission of the European Space Agency ESA for the LISA mission. LISA Pathfinder demonstrated central LISA technologies with which the first gravitational wave observatory in space will observe low-frequency gravitational waves.
LISA technology is now being used for Earth observation and will improve future satellite geodesy missions. GRACE Follow-On observes the critical indicators of climate change through changes in Earth's gravitational field.
Rainer Weiss talks about how the long collaboration with the Max Planck Society's gravitational-wave researchers has shaped this field of science from the very beginning and how their findings helped him with the first LIGO study.
The proposal to include the Einstein Telescope, a pioneering third-generation gravitational-wave (GW) observatory, in the 2021 update of the European Strategic Forum for Research Infrastructures (ESFRI) roadmap has been submitted.
Researchers from the AEI in Potsdam and from the CEA in Saclay, Paris suggest how the planned space-based gravitational-wave observatory LISA can detect exoplanets orbiting white dwarf binaries everywhere in our Milky Way and in the nearby Magellanic Clouds.
