<b><a href="http://www.ubuntunet.net/African_radio_astronomers" target="_blank">http://www.ubuntunet.net/African_radio_astronomers</a><br><br>First point-to-point research network circuit between Europe and
Africa enables astronomers to create a more detailed view of the
universe<br></b><br><b>Lilongwe, Malawi, 25 April 2012</b>: Radio
astronomers in Africa and across the globe will benefit from faster
collaboration through a dedicated, high speed 15,000 km network link
between the pan-European GÉANT and African UbuntuNet Alliance education
networks announced today. <br>
<br>The 2Gbps point-to-point circuit will enable astronomers at the
Hartebeesthoek Radio Astronomy Observatory (HartRAO) in South Africa to
stream observational data to the Joint Institute for VLBI in Europe
(JIVE) in the Netherlands for processing and correlation, and is the
first point-to-point circuit between GÉANT and UbuntuNet. <br>
<br>HartRAO, located in a valley in the Magaliesberg hills, 50 km west
of Johannesburg, is the only major radio astronomy observatory in
Africa. Through the technique of Very Long Baseline Interferometry
(VLBI), it collaborates with radio telescopes on other continents to
form a virtual telescope the size of the Earth.<br>
<br>Combining observations from multiple telescopes using VLBI allows
more detailed observations of distant astronomical objects than with any
other technique. Information is sent in real-time from radio telescopes
around the world to JIVE, where these enormous volumes of simultaneous
observation data are correlated to form high resolution images of cosmic
radio sources. <br>
<br>The establishment of the point-to-point circuit is part of the
European VLBI Network’s (EVN) e-EVN development programme for electronic
VLBI (e-VLBI). This uses high speed research networks to transfer data
for processing in real-time is an alternative to the traditional VLBI
method of recording and shipping data on disk. e-VLBI enables
observations of transient phenomena such as supernovae, using the
highest resolution astronomical technique possible. <br>
<br>“This is collaborative research and education networking at its
best,” said Dr F F (Tusu) Tusubira, CEO of the UbuntuNet Alliance.
“Providing a point-to-point link between Hartebeesthoek and JIVE in the
Netherlands benefits the entire global radio astronomy community, as it
enables faster, more detailed observations to be shared in real-time and
consequently dramatically increases our knowledge of the universe.” <br>
<br>The point-to-point circuit will seamlessly add the 26m telescope at
Hartebeesthoek into the e-EVN array at the highest possible data rate.
It will be used for a series of 10 observing sessions annually to
observe targets that would benefit from the rapid turnaround that
analysing the data in real time provides. The fast turnaround of results
through the e-EVN enables decisions on further observations to be made
whilst the astronomical event is still in progress, thereby enabling the
study of more rapid transients, such as supernovae.<br>
<br>“This new link between Africa and Europe is the perfect example of
close co-operation between research networks across the globe, working
together to provide astronomers and scientists with the infrastructure
they need to advance their work,” said Cathrin Stöver, Chief
International Relations Officer, DANTE, the organisation which on behalf
of Europe’s National Research and Education Networks (NRENs) has built
and operates the GÉANT network. “As the first point-to-point link
between Europe and Africa, it shows the truly global nature of research
and should encourage even greater collaboration between the two
continents moving forward.” <br>
<br>For the global radio astronomy community, adding HartRAO into the
e-EVN array will improve the North/South resolving power, thereby
allowing more detailed source structure to be seen, especially in the
southern sky. <br>
<br>Research data gathered at HartRAO, a member institution of the South
African national research and education network (NREN), TENET, flows in
succession across the networks of TENET, UbuntuNet, GÉANT and Dutch
NREN SURFnet. <br>
<br><b>About GÉANT</b><br>GÉANT is the high speed European communication
network dedicated to research and education. In combination with its
NREN partners, GÉANT creates a secure, high-speed research
infrastructure that serves 40 million researchers in over 8,000
institutions across 40 European countries. Building on the success of
its predecessors, GÉANT has been created around the needs of users,
providing flexible, end-to-end services that transform the way that
researchers collaborate. GÉANT is at the heart of global research
networking through wide ranging connections with other world regions,
underpinning vital projects that bridge the digital divide and benefit
society as a whole. <br>
<br>Co-funded by the European Commission under the EU’s 7th Research and
Development Framework Programme, GÉANT is the e-Infrastructure at the
heart of the EU’s European Research Area and contributes to the
development of emerging Internet technologies. The project partners are
32 European National Research and Education Networks (NRENs), TERENA and
DANTE. GÉANT is operated by DANTE on behalf of Europe’s NRENs. For more

<br><b>About UbuntuNet Alliance</b><br>UbuntuNet Alliance is the
regional Research and Education Network for East and Southern Africa. It
is an Alliance of 13 NRENs in the region aiming at interconnecting with
each other and connecting to other regional networks globally. The
Alliance is also working towards enabling collaboration in research and
education over world class networks. The Alliance was established in
2005 and registered in 2006 as a not-for-profit regional association of
NRENs in Eastern and Southern Africa. It has participated in several EU
FP7 projects and is committed to the role of the advanced networks in
unlocking Africa’s intellectual potential by ensuring that African
Researchers and Educators achieve equity with the rest of the world
through equitable access to global knowledge infrastructure. The
Alliance is working with DANTE on the implementation of the
AfricaConnect project which builds on a proven relationship between
Europe and sub-Sahara Africa.<br>
