ELiTES The European-Japanese collaboration in Gravitational Wave research Dr. Michele Punturo Istituto Nazionale di Fisica Nucleare (INFN) European Gravitational Observatory

Japan Society for the Promotion of Science What is ELiTES? The acronym ELiTES stands for: ET LCGT Telescopes: Exchanges of Scientists Let analyse the name of the project That is easy! But exchange from …. to ….? FP7-European Commission ELiTES € ELiTES ELiTES ￥ ELiTES Japan Society for the Promotion of Science ELiTES 3rd ELiTES meeting

What is ELiTES? The acronym ELiTES stands for: What are ET and LCGT? ET LCGT Telescopes: Exchanges of Scientists What are ET and LCGT? ET is a (project for a far) future Gravitational Wave (GW) Observatory in Europe LCGT, now named KAGRA, is a (near) future GW detector under construction in Japan Prof. Kentaro Somiya will introduce you to the GW physics, whereas I would like to explain you why and how we are collaborating 3rd ELiTES meeting

Gravitational Waves GW are foreseen by the General Relativity of Albert Einstein and are emitted in catastrophic events in the universe: Coalescences of Neutron Stars or Black Holes Supernovae Explosions Big Bang To detect the emitted GW a series of giant detectors has been realised 3rd ELiTES meeting

Science is competition A series of detectors has been active in the World in the 2000-2011 decade GEO, Hannover, 600 m LIGO Hanford, 4 km: 2 ITF on the same site! TAMA, Tokyo, 300 m Virgo, Cascina, 3 km LIGO Livingston, 4 km 3rd ELiTES meeting

Science is competition A new detector is under construction in Japan (KAGRA), the others are under upgrade (new technologies) GEO, Hannover, 600 m ~2018 aLIGO Hanford, 4 km 2015 ~2022 2016 AdV, Cascina, 3 km aLIGO Livingston, 4 km 3rd ELiTES meeting

Science is collaboration To reconstruct the position in the Universe of the GW source, we need at least 3 detectors in the world (better if 4, 5, …) 3rd ELiTES meeting

Science is collaboration It is not a series of detectors, but a network of detectors GEO, Hannover, 600 m DATA ~2018 aLIGO Hanford, 4 km 2015 ~2022 2016 AdV, Cascina, 3 km aLIGO Livingston, 4 km 3rd ELiTES meeting

Science is collaboration Exchange of technologies WP1, WP2:Suspensions materials, fibres WP1: Suspensions design and test WP3: Infrastructures & Vacuum apparatuses WP2: Coatings, Optics 3rd ELiTES meeting

Conclusions This is the 3rd ELiTES general meeting, organised in Tokyo and hosted by the European Delegation probably one more meeting remains (early in 2016), but we are already thinking to the future (H2020?), because we need to collaborate if we want to achieve our scientific targets 3rd ELiTES meeting
