EOSCpilot Science Demonstrator: VisIVO: Data Knowledge Visual Analytics Framework for Astrophysics

OBJECTIVES

The VisIVO Visual analytics tool is devoted to studying star formation regions handling massive and heterogeneous volumes of information related to several galactic surveys processed by data mining algorithms and advanced analysis techniques. Thanks to the highly interactive visual interfaces the tool offers scientists the opportunity for an in-depth understanding of massive, noisy, and high-dimensional data. The aforementioned challenges demand an increasing archiving and computing resources as well as a federated and interoperable virtual environment like the one being developed within the European Open Science Cloud-enabling collaboration and re-use of data and knowledge.

MAIN ACHIEVEMENTS

The project is expected to produce the following outcomes for the astrophysics community engaged in star formation studies:(i) integration of visual analytics tools with EOSC services; (ii) optimization of the archiving of multi-wavelength surveys; (iii) increase of computing resources for analysis (e.g. for calculation of spectral energy distributions); (iv) a federated virtual environment enabling collaboration and re-use of data and knowledge.

IMPACT

  • Publishing a data analysis and visualization environment fully integrated with a relevant set of astrophysical datasets

RECOMMENDATIONS FOR THE IMPLEMENTATION

The VisIVO Science Demonstrator is requiring the use of the European Open Science Cloud technologies for the archive services and the intensive analysis employing the connection with the ViaLactea Science Gateway. The implementation of the Science Demonstrator needed the integration of the ViaLactea Science Gateway with the federated Identity Providers (via the EGI Check-in service) and with the EGI Federated Cloud to expand the computing capabilities making use of a dedicated virtual appliance stored into the EGI Applications Database.

FAIR DATA CHALLENGES

  • catalogues expose a rich set of metadata
  • catalogues include compact sources, filaments etc. that can be searched by specifying the object identifier
