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 ….?

3. 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

4. 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

5. Science is competition
A series of detectors has been active in the World in the 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

6. Science is competition
A new detector is under construction in Japan (KAGRA), the others are under upgrade (new technologies)

3rd ELiTES meeting

7. 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, …)

8. Science is collaboration
It is not a series of detectors, but a network of detectors

3rd ELiTES meeting

10. 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
