Welcome

Welcome to the Joint Institute for VLBI, an European Research Infrastructure Consortium. Our primary task is to operate the data processor for the European VLBI Network (EVN). JIVE provides support to the world-wide EVN user community and also supports EVN operations. JIVE is hosted by the Netherlands Institute for Radio Astronomy (ASTRON).

Array of radio telescopes reveals explosion on the surface of a hot dead star An international group of researchers observed a source of variable gamma rays identified in 2010 by the NASA satellite Fermi. They used a technique called VLBI, that combines data from several radio telescopes on Earth, to produce the sharpest images. Surprisingly, the source of gamma rays was a symbiotic nova, a peculiar stellar system known to astronomers as V407 Cyg. These stellar systems were not known to emit very high energy radiation, therefore with the observations in 2010, Fermi identified the first member of a new class of objects.The astronomers now released the results of their VLBI campaign carried out during the spectacular outburst that produced the gamma rays. The images, compiled using the radio waves detected by telescopes in Europe and in the US, are the most detailed to date. They reveal the aftermath of a powerful cosmic explosion due to the interaction of two stars on close orbit.
