On Tuesday 29 June 2021, the Special Session "Extreme astrophysics at extremely high resolution" will highlight the latest scientific results of high-resolution radio instruments, such as the European VLBI Network (EVN) and similar arrays, with particular focus on the synergies with high resolution and high energy phenomena across the electromagnetic spectrum. The session is being organised with the support of the H2020 JUMPING JIVE project as part of the European Astronomical Society 2021 (EAS 2021) Annual Meeting held virtually from 28 June to 2 July 2021.

The main goal of the session is to highlight the scientific possibilities that can be achieved when joining VLBI with other observational techniques, from the connection between radio-jets and neutrino emission, to the latest observations of Fast Radio Bursts and stellar evolution. The online EAS 2021 Special Session will comprise a wide range of presentations covering the current hot topics of multi-wavelength and multi-messenger astrophysics: several invited talks of 25 minutes and solicited talks of 15 minutes, by a range of experts invited by the SOC. In addition, it will include a limited number of brief contributed talks and 1-minute  ePoster presentations.

European Astronomical Society 2021 Meeting

The European Astronomical Society (EAS) Annual Meeting has more than 25 years of tradition and it has imposed itself as the largest conference for European astronomy. In addition to plenary sessions and the award of prestigious prizes, the conference hosts many symposia held in parallel, as well as special sessions and meetings. 

After the shift to an EAS 2020 virtual meeting, EAS 2021 should have been held physically in Leiden, The Netherlands. Due to the uncertain COVID-19 situation in Europe and the world, the meeting was (again) moved to a virtual meeting, resulting in the registration of over 2000 participants so far.

More information about the EAS 2021 Conference can be found here.

Additional information

The H2020 JUMPING JIVE project aims to take Very Long Baseline Interferometry (VLBI) into the next decade, with JIVE and the European VLBI Network (EVN) as globally recognized centres of excellence in radio astronomy. The project brings together scientists and engineers to define the future of VLBI for scientific applications, and identify the required technological innovation to realise such a future. JIVE is leading the project and twelve institutes from eight different European countries have teamed up in JUMPING JIVE. 

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 by the Netherlands Institute for Radio Astronomy (ASTRON) in the Netherlands.
