European VLBI Network Call for Proposals is open

Published on 31 August 2021

Observing proposals are invited for the European VLBI Network (EVN). The deadline for proposal submission is 1 October 2021 at 16:00 UTC. See the Call for Proposals text here for full information about the call and how to submit proposals.

The EVN facility is open to all astronomers. Astronomers with limited or no VLBI experience are particularly encouraged to apply for observing time. Support with proposal preparation, scheduling, correlation, data reduction and analysis can be requested from the Joint Institute for VLBI ERIC (JIVE).

    User support and the Transnational Access Programme

    Please contact the JIVE support scientists (at in advance, if you need help with preparing your proposal. User support is available in all stages of preparations, observing and data reduction. Travel support through the Trans-National Access Programme returns starting on 1 March 2021 through the new OPTICON RadioNet Pilot project – see the EVN Travel support pages.

    Additional information

    The European VLBI Network (EVN) is an interferometric array of radio telescopes spread throughout Europe, Asia, South Africa and the Americas that conducts unique, high-resolution, radio astronomical observations of cosmic radio sources. Established in 1980, the EVN has grown into the most sensitive VLBI array in the world, including over 20 individual telescopes, among them some of the world's largest and most sensitive radio telescopes. The EVN is composed of 13 Full Member Institutes and 5 Associated Member Institutes. 

    The Joint Institute for VLBI ERIC (JIVE) has as its primary mission to operate and develop the EVN data processor, a powerful supercomputer that combines the signals from radio telescopes located across the planet. Founded in 1993, JIVE is since 2015 a European Research Infrastructure Consortium (ERIC) with seven member countries: France, Italy, Latvia, the Netherlands, United Kingdom, Spain and Sweden; additional support is received from partner institutes in China, Germany and South Africa. JIVE is hosted at the offices of the Netherlands Institute for Radio Astronomy (ASTRON) in the Netherlands.
