A&A has been immediately recognized as a key discipline for EGEE thanks to the success of two pilot astrophysical applications, Planck and MAGIC. After its creation the cluster grew in terms of users and applications. In EGEE-III some funds have been allocated to support disciplinary clusters in their activities; in this way it was possible to hire some man-power mainly dedicated to the application porting and to training activities. Many astrophysical Institutes and research groups are now part of the cluster. Why an A&A cluster Key objectives: Enhance the number of applications ported on the EGEE Grid InfrastructureEnhance the number of applications ported on the EGEE Grid Infrastructure Prepare the A&A community in view of the transition to EGIPrepare the A&A community in view of the transition to EGI Train new research groups in learning and using the GridTrain new research groups in learning and using the Grid Make the Grid and the Virtual Observatory fully interoperableMake the Grid and the Virtual Observatory fully interoperable A&A VOs in EGEE Two Astrophysical VOs are dedicated to the two pilot applications: Planck and Magic.Two Astrophysical VOs are dedicated to the two pilot applications: Planck and Magic.
