EGO takes its name from the European Gravitational Observatory (EGO), a consortium formed to ensure the long-term scientific exploitation of the VIRGO interferometric antenna, a large interferometer designed to detect the gravitational waves predicted by Einstein’s general theory of relativity. VIRGO’s high sensitivity enables detection of the gravitational radiation produced by supernovae and coalescence of binary systems in the milky way and in outer galaxies. The signals are detected, recorded and pre-analysed through an on-line computing system.

EGO-VIRGO maps gravitational-wave (GW) sky localisation signals through all-sky images. However, these images are irregularly shaped and, in order to improve scientific discovery, EGO-VIRGO aims to develop a new Multi-Order Coverage (MOC) map. Not only will this allow the mapping of complex sky regions but also the identification of the credible regions of the GW sky localisation thanks to a multi-scale mapping based on HEALPix sky tessellation.  It is likely that there are storage, computing and workflows that could support EGO-VIRGO on overcoming its challenges. This is where ESCAPE comes into place.

ESCAPE provides technical support and promotes cross-collaboration by connecting ESFRIs from astronomy, astroparticle and particle physics

Many services to support innovation in science

ESCAPE is providing EGO-VIRGO with support to develop a multi-order skymap format and a spacetime MOC. Part of this support is provided through the ESCAPE Virtual Observatory (VO), a service which integrates distributed infrastructures into one single virtual astronomy facility. Thanks to the ESCAPE Open-source Scientific Software and Service Repository (OSSR), EGO-VIRGO can access a wide list of software and innovative tools regarding advanced techniques for data analysis. The ESCAPE Service Analysis Platform (SAP) has the possibility to access and combine data from multiple sources and then process and analyse it.

The feature “Authentication, Authorization and Identity Management” from ESCAPE Data Infrastructure for Open Science (DIOS) is being considered by EGO-VIRGO to provide a uniform identity management layer across the collaborations participating in gravitational-wave research. This feature will allow a more seamless and simple way of interoperating the computing resources used by different initiatives. Finally, the Zoom Universe platforms used by ESCAPE Citizen Science (CS) can support EGO-VIRGO on the classification of data sets produced by EGO-VIRGO. Another way to foster innovation in science and technology

Facilitating the transition to the next generation of gamma-ray, neutrino and gravitational wave observatories

For EGO-VIRGO, the cross exchange promoted by ESCAPE among the ESFRIs is an extremely important “asset”. The exchange of best practices and the creation of a common culture between different communities, is the right step towards and innovative and multidisciplinary joint research.
