The 16th European VLBI Network Symposium and Users' Meeting conference discussed major achievements and challenges in the development of the European VLBI Network (EVN), focusing on the implementation of new technologies and interdisciplinary scientific collaboration, such as:
1. Introduction of new frequency band receivers and development of antennas
The conference focused on the improvement of EVN, in particular using high frequency bands such as K, Q and W-band receivers. Projects focused on developing new antenna arrays inspired by SKA (Square Kilometre Array) and ngVLA (Next Generation Very Large Array) designs to improve the efficiency of radio astronomical observations were presented.
2. Industry impact on frequencies reserved for radio astronomy
Several papers highlighted the increasing competition between radio astronomy and industry needs such as mobile networks and satellite communication services that use radio astronomy frequencies. This trend raises concerns about the future availability of resources for scientific observations.
3. Improvements in data processing and quicker access to the data from scientific observations
JIVE representatives reported on the increasing EVN workload and encouraged the increased use of e-VLBI mode, which allows faster availability of observational data, an essential factor for PhD students to complete their work on time. . Ideas were put forward at the conference to produce and store "science ready" data in the EVN archive to make it more accessible to the wider scientific community.
This conference marks an important step in the development of European radio astronomy, addressing both technological and political challenges.

Oskars Teikmanis, Chairman of the Board of the Latvian Association of Young Researchers (LJZA), presented the diverse career paths and opportunities available to early-career researchers. He emphasised that a career in science is not limited to conducting research but can also develop in areas such as scientific publishing, research integrity, science policy, research funding, administration, innovation, and science communication. A doctoral degree demonstrates not only scientific qualifications but also a broad range of competencies that can be applied across various professional fields. The Career Day also featured a networking session, providing participants with an opportunity to engage in discussions, exchange ideas, and establish collaborations with fellow early-career researchers, doctoral students, doctoral supervisors, project representatives, and industry professionals. In addition to presentations and discussions, participants explored the research infrastructure of Ventspils University of Applied Sciences by visiting the laboratories of the Faculty of Information Technologies. The event concluded with a visit to Irbene, where participants took a guided tour of the Ventspils International Radio Astronomy Centre, learning about its research infrastructure and how it is used in scientific research.
The Engineering Research Institute “Ventspils International Radio Astronomy Centre” (VIRAC) of Ventspils University of Applied Sciences is organising the seminar “Artificial Intelligence Tools and Agents: Their Use in Software Development and Radio Astronomy Data Processing” to introduce the capabilities of artificial intelligence (AI) agents and their practical applications in the development of smart technologies and scientific research. The seminar will take place on 15 October at 10:30 and will be led by Jānis Šteinbergs, Scientific Assistant at VIRAC.
Andris Vaivads, Rector of Ventspils University of Applied Sciences, has been elected as a new foreign member of the Royal Swedish Academy of Sciences' Class for Astronomy and Space Science. Andris Vaivads studies what is commonly known as the magnetosphere around the Earth, other planets and the SunClass for astronomy and space science. He performs his research as a professor in Experimental Space Physics at KTH Royal Institute of Technology in Stockholm. Earlier, he spent 20 years as a researcher at the Swedish Institute of Space Physics in Uppsala. He studies the magnetosphere around Earth, other planets, and the Sun. Much of space is filled with plasma, a gas consisting of electrically charged particles that are influenced, among other things, by magnetic fields. When magnetic fields pointing in different directions reconnect – a process known as magnetic reconnection – large amounts of magnetic energy can rapidly be converted into other forms of energy, including kinetic energy. Andris Vaivads’s research focuses on these processes, where large amounts of energy are converted within small regions of space. Plasma processes can, among other things, produce the Northern lights (Auroras), affect satellites, and heat plasma to tens and hundreds of millions of degrees. The research group at KTH, in which Andris Vaivads spends 20 per cent of his working time, develops instruments to measure electric fields on satellites. The group also designs small measurement probes that can be launched from Esrange Space Centre in Kiruna on rockets. More recently, Andris Vaivads has also studied processes in the solar wind, a kind of plasma wind that plays a major role in space weather. This research uses observations from spacecraft launched by ESA (Solar Orbiter) in Europe and NASA (Parker Solar Probe) in the US. Members of the Royal Swedish Academy of Sciences serve on committees and participate in classes that initiate investigations, respond to consultations, and organise conferences and seminars.

As the availability of artificial intelligence (AI) tools continues to grow, so do their capabilities and the range of tasks they can perform, including increasingly complex and sophisticated ones. Consequently, AI is finding applications in ever narrower and more specialised fields. Scientific research in astronomy is no exception, including radio astronomy and related theoretical fields, which are among the areas of research pursued by scientists at the Ventspils International Radio Astronomy Centre (VSRC) of the Institute of Engineering at Ventspils University of Applied Sciences. AI is based on existing knowledge and cannot independently interpret newly generated scientific results. Nevertheless, AI-assisted data processing, generation of program code, partially repetitive data rows and other types of information, as well as the initial compilation and review of large volumes of information on a scientific topic or, for example, the operation of an existing program, can facilitate certain tasks when carried out under careful supervision and verification by a researcher. The results can, in turn, be checked using another version of an AI agent. However, these approaches do not necessarily reduce the overall amount of work or the time required to complete it. To make the most effective use of the opportunities offered by AI and to communicate this knowledge in an accessible way so that it can subsequently be learned and adopted by everyone involved in research, including members of the older generation of scientists, VSRC launched a series of seminars on the use of AI in science in autumn 2026. The series places particular emphasis on astrophysics and radio astronomy, including radio interferometric observations using the Irbene Radio Telescope (IRT) and the LOFAR network. The first seminar was led by VSRC scientific assistant Gints Jasmonts, who shared his knowledge and experience on 3 September. He provided an introduction to the world of AI and presented examples from his own work in computer science and astrophysics. The discussion focused primarily on large language models available through chat interfaces, search engines and programming environments. At their core, these AI systems operate by predicting the next word or token based on the preceding context. The seminar concluded with a discussion, which revealed that participants are already using AI in their everyday work. At the same time, it became clear that learning how to apply the diverse capabilities of AI specifically to research will require further learning. The next seminar will therefore have a more practical focus.
