LOFAR AND AFRICA

DST – South Africa
ASTRONOMY IN SOUTHERN AFRICA
• South African government has significantly increased science and technology funding
• Prioritized science with a geographical advantage – e.g. astronomy and paleontology
• Aim is to make Southern Africa a hub for Southern Hemisphere astronomy – HESS, SALT, MeerKAT and hopefully SKA and CTA
• DST has allocated R2.3 billion (€228 million) up to 2013 to MeerKAT, SKA site bid and the associated Human Capital Development Programme – Youth into Science and Engineering
ASTRONOMY IN AFRICA
• SKA bid is an African bid – South Africa, Namibia, Botswana, Mozambique, Mauritius, Madagascar, Kenya, Zambia, Ghana
• Endorsed by Southern African Development Community
• Astronomy courses started at universities of Nairobi, Antanarivo, Mondlane (Maputo) as a direct result
• Radio telescope in place for a long time in Mauritius
• Africa SKA group looking at building outstations linked to MeerKAT for VLBI in some or all partner states
• Nigeria building a dish
RADIO ASTRONOMY RESERVE
• RA reserve established in the arid Northern Cape
• Protected in terms of the Astronomy Geographic Advantage Act
• MeerKAT site and proposed SKA site• PAPER and C-BASS being constructed
there• First observations with PAPER show very
good environment
MeerKAT
• Specs developed together with Science Advisory Committee, which includes Director of ASTRON
• Aiming at sensitivity, dynamic range and resolution to complement surveys at many wavelengths, including LOFAR
• Good for low surface brightness but with good position resolution and polarization
• First phase aims for 600MHz – 2.4GHz and possibly 8-15GHz
MEERKAT SCIENCE RFP
• Science to start in 2013• Huge response from international scientific
community – may have to group some of the MeerKAT survey proposal teams.
• Proposals received from many institutions including from the following countries:– UK, USA , Australia, Germany, France, Netherlands ,
Canada, Japan, Italy, Ireland, Poland, Russia, Spain, Portugal, India, Mauritius, Sweden, Korea
AFRICAN PARTICIPATION
• Proposals will be consolidated into a smaller number
• About 40 South African and African astronomers from 8 South African universities and 2 NRF national facilities are members of the MeerKAT survey proposal teams.
MeerKAT and LOFAR
• Good opportunities for collaboration on follow-up observations from LOFAR surveys, magnetic field science, HI science, galaxy and radio galaxy science, pulsars and transients
• Several instruments exist for exchange programmes between Netherlands (EU) and South Africa
• Already very good collaboration between ASTRON and South African astronomers on HI science and other MeerKAT science
• LOFAR technology development relevant to MeerKAT and collaboration will be further explored (e.g. data pipelines, calibration)
MeerKAT and VLBI
• Will phase MeerKAT antennas to give an equivalent VLBI antenna of about 100m in diameter
• This will give great sensitivity on the long baselines to Europe and the EVN
• E-connectivity already demonstrated between JIVE and HartRAO. Wide bandwidths will be available to MeerKAT as well
• Connect to proposed VLBI / geodesy outstations across Africa
