SKA preconstruction phase continuation at UCL

Lead Research Organisation: University College London
Department Name: Physics and Astronomy

Abstract

The Square Kilometre Array will be the largest radio facility every built. It will cost all the member countries 650MEuros to build in its first incarnation. It will be able to provide the most accurate radio images every taken and will touch several areas of physics including Cosmology, Galaxy Formation, Galaxy Evolution, The Cradle of Live, Fundamental tests of General Relativity via Pulsars as well as tests of Cosmic Magnetism.

In order to build such an instrument the participating countries are funding a large effort to design such an array by outlining algorithms and pipelines which will be sufficient to solve the data reduction issues which will be faced by this enormous project. The aim of this project will be to contribute to this design phase and perform the necessary tasks which will enable the SKA to start its construction phase in 2016.

Planned Impact

The Square Kilometre Array will be a massive project with numerous links to industry. Our group will contribute to the PROT.ISP work package which will establish links and hardware requirements for the Square Kilometre array. The impact of such project will be massive as it will require close links with the computing industry for data analysis and correlations of the raw radio data.

Description The consortia we were members of and participated completed their CDR recently.
Exploitation Route The findings from the consortia will be used now in the construction phase of the telescope.
Sectors Digital/Communication/Information Technologies (including Software),Education,Electronics,Other
 
Description The SKA is on its path co complete its construction phase which will be a large and substantial landmark in the engagement we have with the public. It will be a landmark telescope which will yield observations never made before. It wil lalso have an impact on the economy as the construction phase will allow the community to engage industry to help building this telescope.
