Radio Grid Maps the Stars

Today, collaborators in the EXPReS project (Express Production Real-time e-VLBI Service) conducted the first successful real-time correlation of e-VLBI data from Chinese and Australian telescopes, from Chinese and European telescopes, and from Australian and European telescopes. The observation was demonstrated before advanced networking experts at the 24th APAN (Asia-Pacific Advanced Network) Meeting in Xi’An, China.
e-VLBI is a technique by which widely separated radio telescopes simultaneously observe the same region of sky, and data from each telescope are sampled and sent to a central processor via high-speed communication networks operating in real-time. This central data processor, a purpose-built supercomputer, decodes, aligns and correlates the data for every possible telescope combination and can generate images of cosmic radio sources with up to a hundred times better resolution than images from the best optical telescopes.
“This is a fantastic achievement,” said Huib van Langevelde, director of JIVE, present at the APAN meeting in China. “When we started doing e-VLBI we wondered whether we would ever be able to connect to these far-away telescopes, because there are not only various oceans to cross but also many different network providers.” Full Story


About Rich
FlexRex began his life as a cartoon character I created a Sun Microsystems. As the world's first "fictional blogger," he appeared in numerous parody films that made fun of the whole work-from-home thing. Somewhere along the line, the Sun IT department adopted FlexRex as their spokesman in a half-dozen security awareness films for employees. So when I left Sun recently, I started FlexRex Communications, a Marketing company in Portland, Oregon.
