The European VLBI Network

The EVN is a collaboration of the major radio astronomical institutes in Europe, Asia and South Africa and performs high angular resolution observations of cosmic radio sources. An overview of the EVN can be found in our Introduction to the EVN. The EVN is a large scale astronomical facility that is open to astronomers from all over Europe and the rest of the world. You can consult the current Call for Proposals and the EVN User Guide for help with proposing, scheduling, observing and reducing EVN data.

EVN users can download their data from the EVN Data Archive. Data are made public once the 12-month proprietary period has expired (6 months for Target-of-Opportunity observations). For more details, please read the EVN Data Access Policy.

The EVN, as a RadioNet Trans-National Access activity, acknowledges support from the European Commission's Seventh Framework programme under RadioNet.

NEWS: JIVE and the EVN demonstrate ORIENTplus link with e-VLBI observation (posted 15 April 2013)

JIVE and the EVN, including Shanghai Astronomical Observatory, have conducted an e-VLBI observation as a live demo of the newly upgraded 10 Gbps ORIENTplus link between China and Europe. Read the joint JIVE/EVN press release.

NEWS: A Boost for European Radio Astronomy (posted 5 January 2012)

The European astronomy collaboration RadioNet has been granted 9.5 million Euros by the European Commission to fund its latest program, RadioNet3, for the years 2012 to 2015. This not only continues the two preceding European projects, but also takes a leap forward to include ALMA, as well as a number of pathfinder programs for the SKA.

NEWS: Astronomers in the Netherlands catch supernova, observe relativistic expansion (posted 27 January 2010)

Astronomers from JIVE and ASTRON have observed a supernova with peculiar radio emission. In a paper to be published in Nature, the team reports, for the first time ever, detection of a relativistic outflow in a Type Ic supernova, thus supporting the link with the even more energetic Gamma Ray Bursts. Read the full press release.

NEWS: Global e-VLBI observations reveal relativistic jet in a Narrow Line Seyfert 1 galaxy

Astronomers used a global e-VLBI array to unveil the properties of the Narrow Line Seyfert 1 galaxy PMN J0948+0022. During the observations several radio telescopes from Europe, China, Japan and Australia were connected in real-time. The data, part of a multi-wavelength observing campaign, showed evidence for a relativistic jet in this peculiar object. Read more in the EVN Image Gallery.

NEWS: Stations of the Russian VLBI Network KVAZAR Join the EVN

We are happy to announce that the Institute of Applied Astronomy, Russian Academy of Sciences, St. Petersburg joined the EVN in November 2009. The 32m radio telescopes of its KVAZAR network at Svetloe (Sv), Zelenchukskaya (Zc) and Badary (Bd) will be made available for EVN observing sessions. Proposers may request these telescopes in EVN proposals for observations at 18cm, 6cm and 3.6/13cm, beginning with EVN Session 2, 2010.

NEWS:e-EVN aids detection of "extremely prolific supernova factory" (posted 4 December 2009)

The electronic European VLBI Network (e-EVN) was critical in the detection of an "extremely prolific supernova factory" in the buried nucleus of a starburst galaxy last year. The results are published in Astronomy & Astrophysics. Read the full press release.
