Very Long Baseline Interferometry (VLBI) is a technique used in radio astronomy, whereby telescopes spread across the Earth coordinate as an array to produce extremely high-resolution images when studying cosmic radio sources. Such results contribute to answering some of the most fundamental questions in astronomy and physics.
The successful operation of VLBI requires cross-institutional collaboration and coordination – which currently occurs in Europe through the European VLBI Network (EVN) and the Joint Institute for VLBI European Research Infrastructure Consortium (JIVE). The EVN is a network of telescopes and institutions across the globe, and JIVE is the central organisation in the EVN. Data from EVN telescopes is processed at JIVE, which also provides network and user support, conducts leading research and fosters technical development in the field of radio astronomy.
The EVN is currently the most sensitive radio telescope VLBI array in the world – observations conducted using the network have contributed to some of the most ground-breaking research in astronomy and physics. Ensuring the sustainability and progression of JIVE maintains the intellectual capital of the institute and the EVN, as well as guaranteeing the proliferation of technical and scientific knowledge across international borders.
Advances in the development of radio telescopes, such as the Square Kilometre Array (SKA), present opportunities for new science cases, where VLBI will provide essential complementary data. In this context, the JUMPING JIVE project has ensured that the SKA will be technologically compatible with existing telescope arrays, such as the European VLBI Network. JUMPING JIVE has advocated the services of JIVE and explored novel partnerships across and beyond the EVN to strengthen the network in preparation for an era of global VLBI.
