  • Development of the first two prototype CASPER/ROACH boards. Designed by MeerKAT DSP team in cooperation with UCB, laid out at NRAO, being debugged at MeerKAT office. Looks good so far.
  • Zoomed region of interest shows the KAT-7 (Red contours) with SUMSS (green) This is the highest redshift relic detected using SZ effect from the ACT The low frequency image from SUMSS shows possible relics which has then been confined using ATCA observation (priv comm) Our aim was to see if we to do detect diffuse emission from the source using KAT-7 - YES Check for polarised emission - On-going Derive radio luminosity at 1.4GHz and other parameters - on going. SUMSS with a better resolution has resolved this source whereas KAT-7 provides modest resolution of around 3' allowing us to detect the diffuse feature. However, the source is blended with a component in the NW part. The South-East Component detected from KAT-7 has no strong detection from SUMSS. Polarimetric observation using mosaic has been done and is being reduced - this will go about 1/3 times deeper than the total intensity. Magnetic understanding in cluster is still not well understood. With KAT-7 we expected to get an understanding of the large scale magnetic property of this relic source. KAT-7 is an ideal instrument for detecting large scale diffuse emission, that is provided by our short spacings. To get a global picture of the environment of clusters of galaxies for example, we don't want to resolve all the structures.

The SKA is an Opportunity• What we make of it depends on what we put intoit – nothing is given to us on a plate– Science – Nobel Prizes for Africa?– Stimulating interest in science and engineering– Human capital development and skills - critical massof young engineers and scientists with expertise innext-generation technologies (e.g. Big Data; digitalsignal processing; HPC; control etc.) and science– Reverse brain drain– Strengthen universities– Jobs in construction, operations and maintenance– Industry involvement– Spin-offs
    • 28. Example - Big Data• Technologies for SKA are innovative• Big Data creating entirely new industries which willbe very dominant in the global economy – millionsor billions of sensors sending streams of data;huge data sets requiring ultra-fast computing,analysis and visualisation, storage.• SKA >100 x the data traffic of the world-wide web.– An exabyte of data per day – 1018bytes– Exaflop computing speeds – current best is somepetaflops. Equivalent would be ~ 108laptops• Use SKA to get young people into Big Data,wireless, signal processing etc. so that Africa canplay a world-leading role in these new industries.

To use the exciting nature of the SKA to create a significant, andinteractive, research community, comprised predominantly of SouthAfricans and people from the SKA SA Partner States in Africa, but workingin science teams with the best researchers in the best universities andresearch institutions in the world.2. To create sufficient technical / on-site capacity to construct, operate andmaintain the MeerKAT, and the SKA.3. To bring students through school and undergraduate study intopostgraduate study in physics / mathematics and engineering.4. To contribute to the high-level objectives of the Department of Science andTechnology and the National Research Foundation, by providing asignificant input of PhDs into the economy and academic teaching and bycontributing to remedying the demographic imbalance in skilledresearchers in South Africa.
    • 113. Principles of SKA SA’s HCD strategy1. Implement a pipeline model2. Consciously and deliberately address issues of inequality inscience and engineering research3. Attract the best and the brightest young people, by beingfinancially competitive and providing a platform forinnovative research.4. Retain the best and the brightest young people by providingcareer advancement opportunities, access to internationalresearch and creating a dynamic and interactivecommunity around the MeerKAT and SKA.

    • 119. Principles underlying the SKA SA’s HCD strategy• Retain the best and the brightest young people byproviding career advancement opportunities, accessto international research and creating a dynamic andinteractive community around the MeerKAT and SKA.– Retain people by ensuring recognition and researchadvancement.– Research and career advancement through access to travelabroad.– Drop-out rate is minimized because SKA SA is an excitingand challenging project.
    • 120. What have we learnt1. Young people are attracted to exciting, mega-scienceand engineering projects.2. Invest in excellence for a higher ROI.3. Capacity development takes a long time and requiresa significant investment - we have to be able attractacademically excellent students in competition withothers and retain them.4. Deliberate capacity development requires a hands-onapproach5. Researchers thrive in an interactive environment.6. A pipeline model works
    • 121. Comments from leading internationalresearchers• Professor Mike Jones (Oxford University) at the student conference: “Yourwork is comparable with that of top students in other countries, and evenwith the work of professional astronomers.”• Professor van Ardenne of ASTRON: “Your deliberate and concentratedcapacity development is unique in the world, and is clearly working”.• The late Prof Steve Rawlings, then Head of Department of AstrophysicsOxford University, UK: "I am really impressed by what I have seen at thisconference and how things have exploded on the science and engineeringside in such a short time scale. South Africa is doing all the right things forthe SKA!"• Dr. Clive Dickinson, staff scientist at CALTECH : “South Africa is the future
    • 122. Schools Programme– Since 2005, the SKA SA has worked with the schools in the townsnear the SKA site.– Improve mathematics and science education, so that studentsfrom this area can become active participants in the MeerKAT andSKA science and engineering programmes.– Facilitated the recruitment of qualified mathematics and scienceteachers, the construction and equipping of a Cyberlab andscience laboratories, astronomy talks, career guidance, teachertraining, role models, holiday programmes, sky viewing sessions,field trips and exchange programmes.– 24 x Grade 9 students from the area have been awardedbursaries by the project to study at Carnarvon High School, theonly high school in the area teaching mathematics andscience.
