article imageWorkshop will gather analysis ideas for SKA

Aveiro - A workshop planned for 24-25 May in Portugal to examine latest information and trends in radio astronomy data analysis, will contribute towards decisions affecting the huge planned Square Kilometer Array (SKA) radio telescope.
The workshop in Aveiro, Portugal, will review current R&D trends in radio-astronomical data analysis.The topics will cover astronomy and space science applications and deal with the technologies being investigated in projects ranging from electronic Very Long Baseline Interferometry (e-VLBI) to the SKA (Square Kilometre Array). Future paradigms for information processing in collaboration with major industrial partners will also be discussed.
The planned SKA, described as tthe 'international telescope for the 21st century' is to be established either in South Africa or Australia.
According to the SKA team, The Square Kilometre Array (SKA) promises to revolutionise science by answering some of the most fundamental questions that remain about the origin, nature and evolution of the universe. With about 3 000 receptors linked together and a total collecting area of one square kilometre, the SKA will have 50 times the sensitivity and 10 000 times the survey speed of the best current-day radio telescopes.
The distributed sensor networks currently used in radio astronomy are generating ever larger amounts of digital data, posing increasing demands on processing, transport and storage facilities. Networked instruments such already send much of their data in real-time via optical fibres, through national and international research networks. Networked infrastructure was critical for the establishment and success of recent telescopes such as ALMA, e-Merlin, LOFAR, e-VLA and e-EVN.
How to utilise the emerging information and communication technology (ICT) infrastructure will be of crucial importance for many SKA Pathfinders.
The SKA and precursors (Meerkat, ASKAP, MWA), and in particular any of their Aperture Array components, will certainly pose additional challenges on connectivity, processing and storage, representing an increase of several orders of magnitude compared to current information processing scenarios and may lead to the usage of new Internet technologies.
This growing connectivity will condition the final computing stages and science exploitation.
