Astronomie - Cutting-edge technology from Hannover for the Virgo gravitational-wave detector in Italy


Squeezed-light source developed at the Albert Einstein Institute to make Virgo even more sensitive to gravitational waves


A team of researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) in Hannover and from the Institute for Gravitational Physics at Leibniz Universität Hannover has developed an advanced squeezed-light source for the gravitational-wave detector Virgo near Pisa. Now, the Hannover scientists have delivered the setup, installed it, and handed it over to their Virgo colleagues. Beginning in autumn 2018 Virgo will use the squeezed-light source to listen to Einstein’s gravitational waves together with the worldwide network of detectors with higher sensitivity than ever before.


Together with their Virgo colleagues, the AEI researchers Harald Lück, Moritz Mehmet, and Henning Vahlbruch install the squeezed-light source, which was developed in Hannover, in a cleanroom at the Virgo gravitational-wave detector. [less]
