A&A Community
• Study the physics of the Universe;
• Observation and simulations;
• Heterogeneous, distributed,
wide community
• Computing (HTC but also HPC)
• Demanding in terms of data

A&A Challenges
• A&A infrastructures
– Virtual Observatory: Astronomical data and service infrastructure
– Project-oriented / community-oriented federations
• Integrating infrastructures
• Smart technologies: hide complexity of the infrastructures and
allow end users to focus on scientific aspects
eScience approach
Data sharing, federated (virtual) research environments and computational resources

The State of the art
•
•
•
•
•
MAGIC and Planck experiments
The A&A VOs (10 with about 500 users)
A light weight coordination
The A&A Heavy User Community
Partnership in EGI-InSPIRE to develop and maintain
services and tools (WP SA3, Task 5) and prepare their
long term sustainability
– Visualization tools
– Interoperability of different DCIs
– Interoperability of DCIs and DDIs

The Fall-Out
• Science gateways as a framework to integrate Applications and
services for A&A (8 SGW)
– SCI-BUS / Science Gateways
– ER-flow / User Communities Applications
– AstroGrid-PL: InSilicoLab for Astrophysics
• Benefits for the big (ESFRI) A&A Projects
– CTA / Virtual Team / focus on SSO and Science Gateways for
Cherenkov Telescope Array
• Trans-national federations and initiatives
– STARnet / Trans-national Federation of thematic astronomical Science
Gateways
• Interoperability between eInfrastructures: EuroVO data and
services cloud.

•
•
•
CTA portal: prototype by Cyfronet and INAF
SKA pathfinder: Evolutionary Map of the Universe a deep survey of the
sky (10mJy/beam) to be carried out at 1.4 GHz with the Australian SKA
Pathfinder (ASKAP).
STARnet Federation
A&A services: e.g. AstroGrid-PL or BaSTI
Engagement of A&A Data Centers: science gateways for data services
Interoperability with International Virtual Observatory:
– Canadian Data Center federated Cloud for Astronomy
– IVOA Grid and Web Services working group
•
Astro-WG and Astro-CG in OGF
– Astro-CG as an international forum where the astro communities and projects
•
•
Meet and bring their experiences and advances
Learn about technology advances
– Liaison with the Virtual Observatory

Closing activities
•
•
•
•
•
Planck ESA satellite mission: measure the CMB.
The workflows are used to develop a web application of the Planck simulation software
based on SSP.
Execute large number of simulations (parameter-sweep)
Estimate the Cosmological Parameters correcting instrumental and observational
systematics.
Planck VO: ~50 users, ~ 20000 Cores, 15TB

A&A in 2015 and beyond
• In the last year there was an increase of 20% of
users in A&A VOs
• Dedicated computing and storage will increase in
2015 (800 cores and 100TB storage, cloud, national
funding)
• Provide an integrated virtual research environment
– solutions for data sharing, visual analytics, data mining
and for supporting collaborations
• Integrated solutions for data and computing (EGI fed
cloud and IVOA cloud)
