About ELGAR

In 2015, one century after Einstein predicted their existence, scientists observed gravitational waves (GW) for the first time. GWs are ripples in the interwoven space-time fabric, which is able to stretch, shrink and jiggle. Complementary low frequency GW observations would naturally complete and enhance the results obtained. The scientific potential of multi-frequency GW astronomy is enormous, in terms of providing a deep view into the cosmos, inaccessible otherwise. This is a unique new opportunity for the future of astronomy, whose success depends on the decisions being made by infrastructures now. The proposal to construct, in space, a Laser Interferometer Space Antenna (LISA) to investigate frequency sources at very low frequency gives a partial, long-term answer to this challenge. Nevertheless, it will leave the infrasound (mHz to tens of Hz) band uncovered, and an underground gravitational wave antenna can provide a quick response to this problem. The European Laboratory for Gravitation and Atom-interferometric Research (ELGAR) proposes to design the first long-baseline infrastructure using quantum physics to study space-time and gravitation. It will directly inherit from the Matter-wave laser Interferometer Gravitation Antenna (MIGA) large equipment under construction in France, and will derive pan-European synergies from top research centers developing quantum sensors in Europe, such as the UK Quantum Technology Hub for Sensors and Metrology as well as the Centre for Quantum Engineering and Space-Time Research in Germany. Likewise, leading quantum sensor laboratories from France, Italy, and Greece will join top research centers in geophysics and in GW astronomy from France, Italy, Germany and Spain. The future infrastructure will focus on enabling GW observation in the infrasound region. However, applications might extend to a larger community, including geology, fundamental physics, gravitation and general relativity.

In respond to the future “INFRADEV-01-2019-2020: Design Studies” call, the ELGAR proposal will design this infrastructure and will address all key conceptual, technical, legal and financial questions to build a roadmap for the infrastructure to meet not only today’s need, but also tomorrow’s challenges.
