EGO & Training
Established in 2004, the VIRGO EGO Scientific Forum
is composed of 47 research groups active in the
European scientific community.
 A total of 18 fellowships with a two-year duration have been
funded in Italy (7), Spain (3), France (2), Germany (2), Greece (1),
Hungary (1), Poland (1) and UK (1).
 A yearly school to introduce Physics students to gravitational

EGO –ICRR Meeting 4/5 October 2011
Present of GW research in Europe
o There is a scientific case
o There are scientific and technological competencies, developed locally
in Laboratories
o There are research infrastructures, thanks to the vision of National
Agencies
o There are industries which provided the high-tech components,
acquiring know-how to be spent on the market
o There are first class World-wide technology transfers and/or spin-off
from EGO/VIRGO and GEO600: (a) mechanics (IT), (b) lasers (DE),
(c) mirrors (FR & DE)
o The two EU interferometers have done a common science run during
summer 2011
o The National scientific communities have demonstrated to be able to
cooperate on a common project (the Einstein Telescope)
o There is a well consolidated management (EU grants, EU projects,
science and technology workshops, R&D, training)
EGO –ICRR Meeting 4/5 October 2011
An EUROPEAN STRATEGY for GW?
EGO & GEO600
A multi-sited Research Infrastructure
Lead 3rd Generation Interferometers
Local & Global
The virtuous quadrilateral:
Research
Technology
Collaboration
Education
EGO –ICRR Meeting 4/5 October 2011
EUROPEAN STRATEGY for EGO
Three Steps:
Active participation in EU GW projects
Increase the participation of the National
GW communities in Europe to EGO
Develop the dialogue with the GW
communities in other regions of the World
EGO –ICRR Meeting 4/5 October 2011
Summary
• An efficient, responsive and light structure to
support Virgo and promote European
collaboration under supervision by national
institutions
• EGO existence relies on Virgo/AdV success
Advanced
• The future of GW inVIRGO
Europe depends upon a
stronger collaboration between EU countries.
EGO may prefigure the required infrastructure.
