Scientific Description
The European Very Long Baseline Interferometry Network (EVN) is a distributed network of radio telescopes located across the EU and beyond. EVN telescopes located within the EU include: Effelsberg (DE), Jodrell Bank and Cambridge (UK), Westerbork (NL), Onsala (SE), Medicina, Noto and Sardinia (IT), Yebes (ES), Torun (PL), Metsähovi (FI), and Irbene (LV). When conducting EVN observations, participating telescopes operate as a single entity. Signals from each telescope are combined together at a central processing facility at the Joint Institute for VLBI in Europe (Dwingeloo, NL) for correlation. There are additional EVN telescopes in Russia (3), China (2), South Africa, and Puerto Rico. Joint observations with the UK MERLIN array and telescopes operated by NRAO (U.S.) are made on a regular basis.
