RADIOBLOCKS: A New European Consortium to develop Next Generation Technologies for Radio Astronomy Infrastructures

February 2, 2023

The RADIOBLOCKS project, coordinated by JIVE ERIC and including major European research infrastructures for radio astronomy, together with partners from industry and academia, have been granted 10 M€ by the European Commission to develop “common building blocks” for technological solutions beyond state-of-the-art, that will enable a broad range of new science and enhance European scientific competitiveness. The RADIOBLOCKS project will start on 1 March 2023.

 

The RADIOBLOCKS project will take a holistic view of how radio telescopes arrays capture, process, synthesise and analyse cosmic signals and will develop components, technologies and software, applicable to a wide range of instruments, to enable the next major discoveries in radio astronomy.

 

RADIOBLOCKS aims to achieve a maximal boost for the major world-leading research infrastructures in radio astronomy by developing common needed blocks:

 

●  for the development of new correlators, which can efficiently exploit powerful new commercially available accelerator hardware (GPUs). This development will directly benefit the large radio arrays from meter to sub-mm wavelengths;

●  in cutting-edge frontend technologies, addressing the generation and real-time handling of wide band and multi-band data, in particular for the creation of novel detectors and components, both RF and IF, as well as the design of backends, with built-in RFI mitigation;

●  for multipixel (PAF/FPA) receivers, ranging from cm to submm wavelengths, suitable for large single dish facilities, with special relevance for future collaborations with pan-European and global RIs (e.g., SKA-VLBI).

●  for data (post)processing, testing prototype workflows functionality and demonstrating usage of end-to-end simulation tools.

 

"The project RADIOBLOCKS collects the experience and common interests of the radio astronomy community in Europe at large, including several other global parties and industry. For the first time, all will work together to develop the technologies that are necessary for the future evolution of their facilities. This is a paradigm shift, mostly facilitated by the European Commission's Horizon Europe programme", says Dr. Francisco Colomer, director of JIV-ERIC and coordinator of RADIOBLOCKS.

 

The 4-year RADIOBLOCKS project - funded by the Horizon Europe Framework Programme -

involves 33 major European research infrastructures for radio astronomy, together with partners from industry and academia from 9 European countries, Japan, Republic of Korea, South Africa, and the United Kingdom. The engagement with industry to co-develop advanced technologies will increase the partners’ technological levels and strengthen their market positions.

 

The European research infrastructures (RI’s) involved in RADIOBLOCKS are the Joint Institute for VLBI ERIC (JIV-ERIC) and the European VLBI Network (EVN), the Multi Element Remotely Linked Interferometer Network (eMERLIN), the LOw Frequency ARray (LOFAR/ILT, in the process to become LOFAR ERIC), the Northern Extended Millimetre Array (NOEMA), the 100-metre Effelsberg Telescope, the Sardinia 64-m radio telescope, the Yebes 40-metre telescope, the IRAM 30-metre Telescope and also global facilities of European interest, such as the Square Kilometre Array Observatory (SKAO, an ESFRI landmark), the Atacama Large Millimetre Array (ALMA), the Global Millimetre VLBI Array (GMVA), and the Event Horizon Telescope project (EHT).

 

“The RADIOBLOCKS project brings together world-leading academic research and industry experts from across Europe and beyond to co-develop and then exploit new technologies to maximise the science capabilities of current and future radio facilities,” says Prof. Rob Beswick, Head of Science Operations and User Support for e-MERLIN, the UK’s National Radio Astronomy Facility; Deputy Director of the UK SKA Regional Centre and RADIOBLOCKS lead at The University of Manchester.

 

The project builds on the highly consolidated RadioNet consortium, which, since the year 2000, have been supported by the European Commission through their different Framework Programmes. RadioNet has successfully integrated a unique array of capabilities and contributed to the continued advances in radio astronomy, which are recognised as essential in answering key questions in astrophysics.

 

The RADIOBLOCKS project is coordinated by JIV-ERIC, showing its central role as a coordinating research infrastructure bringing together the major research organisation in the radio astronomy field and its expertise coordinating several EC-funded projects in recent years such as the H2020 JUMPING JIVE.

 

For JIVE ERIC and the EVN, RADIOBLOCKS will have a major impact for the development of a next generation Very Long Baseline Interferometry (VLBI) Correlator. The EVN technology roadmap for 2020-2030 highlighted the need for broad-band developments, extending the observing bandwidth by at least to 5 GHz, which also requires recording the data at a rate of up to 32 Gbps, an observing mode that will be fully compatible with the Square Kilometre Array (SKA-MID). Bringing in the SKA-MID, and several other telescopes is the other way to increase the sensitivity of VLBI observations performed by the EVN. This is particularly important for narrow-band phenomena - like Fast Radio Bursts (FRBs) - where the only way of improving the sensitivity and imaging capabilities is increasing the collecting area (i.e., the number of telescopes, distributed evenly on various angular scales). To be able to process these broad-band data for large number of telescopes (>30), a next generation VLBI correlator, including specific modes optimised for processing large fields of view, short transients (microseconds time scale), and high spectral resolution modes, is necessary.

 

During the RADIOBLOCKS project, the VIRAC team will contribute to the development of a software that will be used for data processing in several VLBI networks (EVN (European VLBI Network), ILT (International LOFAR Telescope), ALMA (Atacama Large Millimeter Array), SKA (Square Kilometre Array), EHT (Event Horizon Telescope)) and will be useful for the whole radio astronomy community. It should be underlined that during the project, the data processing algorithms previously developed by the VIRAC team will be improved and applied to the observational data of the EVN and ILT networks. These algorithms are based on the KLT (Karhunen-Loève transform) and SSA (Singular Spectrum Analysis) methodologies. The results of the project will be used for further development of a single-base interferometer using the RT32 - RT16 interferometer in the Irbene radio telescope complex, and the results will allow the development of LOFAR VLBI capabilities.


“RADIOBLOCKS is an ambitious project that will bring together 33 partners from industry and academia from all over the world.” says Dr. Giuseppe Cimò, head of Space and Innovative Applications at JIVE and Project Manager of the RADIOBLOCKS project. “It will be an exciting challenge to help develop the common blocks that European Research Infrastructures will use to create exciting scientific results to answer key questions in astronomy and astrophysics.”

The RADIOBLOCKS project will receive funding from the European Union’s Horizon Europe research and innovation programme under grant agreement No 101093934.

From Heat Engines to Solar Active Regions: Entropy in the Sun’s Atmosphere

By Rota Žagare • June 18, 2026
A team of solar physicists has discovered a new way to detect and measure entropy variations in the Sun’s atmosphere – a breakthrough that could help researchers better understand how energy moves through the solar corona and why the Sun’s outer atmosphere is millions of degrees hotter than its surface. Entropy is a concept that dates back to the 1860s, when German physicist Rudolf Clausius introduced it while studying the efficiency of heat engines and the famous Carnot cycle. Since then, entropy has become one of the most fundamental ideas in physics, helping scientists describe how energy is distributed and transformed in systems ranging from steam engines and black holes to stars and even the Universe itself. Despite its importance, entropy has remained notoriously difficult to measure directly in the Sun's atmosphere. In a new study currently in press in The Astrophysical Journal Letters, researchers from the University of Warwick, the Ventspils International Radio Astronomy Centre (VIRAC, Ventspils University of Applied Sciences), and University College London have shown that entropy leaves observable fingerprints in waves that travel through the Sun's hot, magnetised atmosphere, known as the corona. "Entropy is one of the key quantities that tells us how energy is organised within a physical system," explains lead author Dmitrii Kolotkov, Stephen Hawking Fellow. "In a conceptual sense, we can think of solar active regions as natural heat engines, continuously converting and transporting energy through hot magnetised plasma. Their behaviour and efficiency are closely linked to entropy. The concept itself has deep roots in thermodynamics and even plays a central role in black hole physics, where entropy is associated with the fundamental limits of information and energy storage. When entropy remains unchanged, energy tends to stay more organised and localised. When entropy is perturbed, energy becomes redistributed and spreads through the surrounding plasma. If we can measure how entropy changes in solar active regions, we gain a new way of tracking how energy is transported, dissipated, and ultimately converted into heat."

First EDI Seminar Implemented within COLOURS

By Rota Žagare • June 8, 2026
On 18 May, the first EDI (Equality, Diversity, Inclusion) seminar, implemented within the COLOURS project, was successfully held at the café “Panorāma.” The aim of the seminar was to promote understanding of equality, diversity, and inclusion, as well as to strengthen cooperation between different groups of society. The seminar brought together 53 participants, including local students, international students, Erasmus+ students, administrative and academic staff, as well as members of the wider community. The event also attracted a broad range of participants: volunteers from the “Youth House,” city residents, secondary school students, participants of the Lifelong Learning Centre (MIC) alumni courses, and a guest lecturer from the University of Brittany in France. This diversity of participants ensured the practical implementation of the Quadruple helix principle, fostering collaboration between academia, industry, society, and the youth sector. The seminar was led by students Līva Slesare, Amanda Gintere, and Tillija Naumann, demonstrating the active involvement and leadership of young people in building an inclusive education and society. All seminar participants received a COLOURS virtual badge, serving as proof of the knowledge and skills acquired, and can be used for personal and professional development, including on LinkedIn profiles. It is planned that starting from autumn 2026, this training seminar will also be offered in an online format in both Latvian and English. This will make it accessible to a wider audience. Everyone – students, staff, and city residents alike – will have the opportunity to participate, gain knowledge about EDI, and receive the COLOURS badge. This initiative is seen both as an opportunity and a responsibility –to jointly build a more inclusive, open, and understanding society.

VUAS adopts policy for equality, diversity and inclusion

By Rota Žagare • May 29, 2026
Ventspils University of Applied Sciences has officially adopted the COLOURS Alliance EDI Policy – a shared framework for equality, diversity and inclusion. The policy will now be adapted and implemented within the university’s operations. The aim is to strengthen inclusion across education, research, and everyday practices. The policy can therefore be seen as both a pedagogical and strategic implementation tool to prevent discrimination, increase understanding of differences, and equip students and staff to perform at their best in diverse teams. EDI stands for equality, diversity and inclusion. The training in EDI is designed to strengthen interpersonal relationships, raise awareness of the value of diversity in innovation, creativity and knowledge development, and encourage reflection on one’s own position and approach to others. The implementation of the policy contributes to the development of generic competences and critical thinking among both students and staff. This EDI policy is part of a much larger context, as we are one of nine higher education institutions in Europe adopting the same framework. EDI as a driver for an inclusive society The policy also emphasizes the importance of collaboration through the Quadruple Helix model, where universities, industry, the public sector, and civil society work together. The goal is not only to develop knowledge within EDI, but also to disseminate it and create societal impact. The policy marks the starting point for new initiatives and serves as a bridge to society. EDI strengthens the quality of education and research and is an important tool for both current operations and future needs. Signed policy is available HERE

Translation programme students expand their knowledge with guest lecturers from France and Poland

By Rota Žagare • May 28, 2026
On Tuesday, May 19th, second year students of the bachelor’s study programme “Translation and Language Technologies” participated in a lecture lead by guest lecturer Aurélie Le Melinaidre from the Southern Brittany University in France. She tested the students’ knowledge of various English idioms, encouraged creativity by asking them to rewrite a text fragment as differently as they could, and was pleasantly surprised by the students’ excellent knowledge of English. Students also learned about the guest lecturer’s experience teaching English in different countries. Guest lectures held on May 20th and 21st were led by guest lecturer Karolina Siwek from Jan Dlugosz University in Poland. The guest lecturer, met through the COLOURS network, gave four interconnected lectures about different translation aspects for the second- and third-year students of the bachelor’s study programme “Translation and Language Technologies”. Karolina Siwek firstly introduced the students to the history of translation, compared what the profession of a translator was like in the 19th and 20th centuries and what it is like today, highlighting the aspects that have remained the same and those that have changed. During Wednesday’s lecture, students had the opportunity to engage in a discussion and compare the nature of the profession, not only from a historical perspective, but also in terms of the current state of the translation industry in Poland and Latvia. During the lecture about the differences between literary and specialised translators, the guest lecturer compared the translator’s visibility in their work, various potential risks during translation, and the necessary skills, as well as discussed about the prestige and income of the profession. Particular attention was paid to hybrid competencies, which play a significant role in the modern translation profession. Meanwhile, on Thursday, a series of related lectures took place about ISO standards and their impact on the daily work of translators, covering both the positive and negative aspects. The guest lecturer also discussed possible emotions of a translator, their causes, and how to manage them, emphasizing, above all, that emotional regulation is a core professional skill for translators. The guest lecturer shared several stories about her experiences, describing how she handled specific situations and what she learned from them, giving the students a realistic insight into the profession of translation and offering useful advice.

By Rota Žagare • May 19, 2026
Three students from Ventspils University of Applied Sciences participated in the student networking event “Meet the Nordics: Insights, career opportunities and networking”, organized by the Nordic Council of Ministers’ Office in Latvia in Riga. The event was organized in cooperation with the embassies of Denmark, Finland, Norway, and Sweden the event brought together students from different universities to explore diplomacy, Nordic-Baltic cooperation, and international career opportunities. Throughout the event, students gained valuable insight into the daily work of diplomats, the challenges of working in international environments, and the skills needed to succeed in diplomacy. The speakers shared not only professional experience, but also personal stories about communication, adaptability, and building a meaningful career in an ever-changing global environment. Second-year student of the bachelor’s study programme “Intercultural Communication”, Luīze Anna Spriņģe , highlighted the networking session as the most memorable part of the event: “This part was the most valuable because we could learn more directly from the professionals and their experience. It was valuable to speak with diplomats in a more open environment where we felt comfortable asking different questions.” She also admitted that it was especially interesting to hear the advice of Norwegian Ambassador Ine Måreng, Finnish Deputy Head of Mission Eero Vento, and Danish Deputy Head of Mission Alexander Lemche on how to stand out professionally and build a career in diplomacy. Additionally, second-year student of the bachelor’s study programme “Intercultural Communication”, Evija Saldaka , emphasized the practical value of the experience: “It was interesting to hear about different career paths and practical examples from the diplomats’ daily work. The networking conversations felt especially useful.” Meanwhile, first-year student of the bachelor’s study programme “Translation and Language Technologies”, Janita Kate Asare , shared that the event gave her a deeper understanding of the responsibility and complexity of diplomatic work. She especially appreciated the discussions about diplomacy, work-life balance, and maintaining professionalism in international environments. The students agreed that international events like this provide much more than new knowledge. They create opportunities to develop communication skills, build meaningful professional connections, and inspire students to think more boldly about their future careers. The event also highlighted that diplomacy is not only about politics or international agreements, but equally about building understanding, trust, and dialogue between people and cultures.
