Join the first online EVN Users' Training Event

On 11 May 2022, JIVE organises the first online EVN Users' Training Event with the aim to support first-time users of the network. EVN Support Scientists will guide participants through the different steps to allow them to prepare and submit an observing proposal as well as the scheduling of observations. Participation on the webinar is free for everyone but registration is mandatory.

European VLBI Network Call for Proposals is open

Observing proposals are invited for the European VLBI Network (EVN). The deadline for proposal submission is 1 June 2022 at 16:00 UTC. See the Call for Proposals text here for full information about the call and how to submit proposals.

2022 European Radio Interferometry School to be hosted in Dwingeloo

The 9th European Radio Interferometry School (ERIS 2022) will be hosted by JIVE and ASTRON in Dwingeloo (the Netherlands) on 19 - 23 September 2022. The school is sponsored by the H2020 OPTICON-RadioNet Pilot (ORP) Project. Registration for the School is currently open and the deadline for registration is 15 May 2022.

Cosmic flashes pinpointed to a surprising location in space

Astronomers have been surprised by the closest source of mysterious flashes in the sky called fast radio bursts. Precision measurements with radio telescopes reveal that the bursts are made among old stars, and in a way that no one was expecting. The source of the flashes, in nearby spiral galaxy M 81, is the closest of its kind to Earth. The research including the participation of JIVE researchers has been published today in two papers in Nature and Nature Astronomy.

A new state-of-the-art receiver for Yebes Observatory's 40-metre radio telescope

The Yebes Observatory (Spain) - managed by JIVE/EVN Partner Instituto Geográfico Nacional (IGN) - Ministerio de Transportes, Movilidad y Agenda Urbana (MITMA) - completed the design, implementation and installation of a new broadband receiver for its 40-m diameter radio telescope. The receiver is sensitive in the 4.5 to 9 GHz frequency range, and replaces two older, frequency-limited receivers in C-band (5 and 6 GHz) and X-band (8 GHz), allowing simultaneous observation in these two bands and in additional, previously unavailable frequencies.

15th European VLBI Network Symposium and EVN Users Meeting Opens Registration

The 15th European VLBI Network (EVN) Symposium, “Providing the Sharpest View of the Universe", and the EVN Users Meeting will be hosted by University College Cork (Ireland) on 11-15 July 2022 as in-person event, with also the option of online participation for those who do not feel able to come to Cork. Registration for the Symposium is currently open and the deadline for abstract submission is 30 April 2022.

Less powerful black hole blows environment clean after all

An international team of astronomers led by JIVE postdoc has discovered that even a weak jet stream from a low-active black hole can be a kind of leaf blower to clean parts of a galaxy. The observed black hole removes about 75% of the cold gas in the central regions of the galaxy in a few million years. This probably stops the formation of stars. The researchers published their findings on Thursday 10 February 2022 in the journal Nature Astronomy.

Breaking the Resolution Boundaries: Observing the supermassive black hole binary candidate OJ 287 from Earth and space

An international team of researchers - lead by the Spanish Institute of Astrophysics of Andalusia (IAA-CSIC) and including participation from a JIVE researcher - has obtained an image of radio emission in the active galaxy OJ 287 at an angular resolution of 12 micro arcseconds, which is presently the highest resolution achieved in astronomical observations.
