Astronomy has a history and a tradition of using remote sites and space missions to gather large amounts of data. Australia hosts SKA pathfinders ASKAP and MWA, and will host SKA1-Low, producing orders of magnitude more data than any other astronomical instruments before. All this data will be used by hundreds of scientists working in multiple institutions across the globe. Australia participates and leads a number of major SKA science themes. In order to fully exploit the scientific potential of the instruments and enable ground-breaking scientific discoveries the SKA community needs to build the expertise and develop the technologies to support the science teams during their scientific exploration of the data products released by the SKA Observatory.

While SKA Observatory is responsible for generation of calibrated data products, the production of more advanced data products, such as science grade catalogues or very deep-stacked image cubes, are within the scope of SKA Regional Centres (SRC). The data volume and the individual sizes of datasets will be very large to be served via traditional data management models making the data centric processing as the preferred model for science data analysis. The data products need to be curated and served according to SKA policies. Multi-messenger data may need to be co-located and co-processed. Distributed science teams will need new tools, methods, frameworks and algorithms to maximise the scientific productivity.

Aiming at developing a prototype of the future infrastructure a three-year design study commenced in April 2017 called ERIDANUS Project. The project will deploy a prototype data intensive research infrastructure and middleware, between and within Australia and China, capable of addressing SKA-class data and processing challenges. The project will respond to the identified challenges, and will collaborate with the Advanced European Network for E-infrastructures for Astronomy with the SKA (AENEAS) project.

The poster outlines the current activities and future plans as undertaken by ICRAR, CSIRO and SHAO as part of the ERIDANUS project.



Dr Slava Kitaeff is the Project Engineer for the SKA Regional Centre and ERIDANUS National Project Lead at the International Centre for Radio Astronomy Research and CSIRO Astronomy and Space Science. Dr Kitaeff’s background is the radio astronomy instrumentation, high performance scientific computing and data management.

About the conference

eResearch Australasia provides opportunities for delegates to engage, connect, and share their ideas and exemplars concerning new information centric research capabilities, and how information and communication technologies help researchers to collaborate, collect, manage, share, process, analyse, store, find, understand and re-use information.
