Approved fundamental and applied research project proposals at Ventspils University of Applied Sciences

January 20, 2023

The project proposals prepared by the Engineering Research Institute "Ventspils International Radio Astronomy Center" (ERI VIRAC) of Ventspils University of Applied Sciences for the Latvian Science Council (LZP) grant competition, project No. lzp-2022/1-0083 "A single-baseline radio interferometer in a new age of transient astrophysics" and project No. lzp-2022/1-0017 "Multi-Wavelength Study of Quasi-Periodic Pulsations in Solar and Stellar Flares," were highly evaluated and financially supported by the LZP's decisions on December 20, 2022.


Both projects are being implemented by the Engineering Research Institute "Ventspils International Radio Astronomy Center" (ERI VIRAC) of Ventspils University of Applied Sciences.


Project No. lzp-2022/1-0083 "A single-baseline radio interferometer in a new age of transient astrophysics" is intended as a fundamental research study aimed at creating the Irbene single-baseline radio interferometer (ISBI), which will be capable of detecting radio emission fluctuations related to high-mass star formation regions. The developed ISBI will be used to observe the continuum emission of high-mass protostars and maser emission lines. The obtained results will help choose between currently untested and competing theoretical scenarios proposed to explain the recently discovered variability of radio radiation observed in high-mass star formation regions.


During the implementation of the project, it is planned to deepen the understanding of the eruption formation process, which is believed to follow flares during which high-mass stars accumulate mass. High-cadence observations using the Irbene interferometric system will be organized to study these processes.


The project includes the following tasks:

  • Expand the existing capabilities of the Ventspils radio observatory by using two radio telescopes (32m and 16m in diameter) in a unified system as an interferometer.
  • Improve and automate the planning of astronomical observations and processes related to the acquisition and analysis of astronomical data.
  • Create a list of approximately 30 high-mass protostars whose radio signal emissions will be simultaneously monitored at 6.7 GHz methanol maser lines and radio C bands.
  • Interpret astronomical data by studying the processes of high-mass star formation and development, thereby understanding the formation of massive stars.
  • Organize public lectures and informative events, and publish the achieved results in scientific conferences and leading astronomy journals.


The results obtained during the project implementation will provide answers to unanswered questions about the processes of high-mass star formation. Additionally, the project team aims to deepen the understanding of the eruption formation process, which is believed to follow flares during which high-mass stars accumulate mass. High-cadence observations using the Irbene interferometric system will be organized to study these processes. Such observations require a combination of effective and specific functional technologies, which are not easy to develop nowadays. The unique advantages of the Irbene interferometer provide an opportunity to research short-term variable astrophysical processes.


The project activities are planned to be implemented from January 1, 2023, to December 31, 2025. The total project funding is 300,000.00 euros, and the scientific leader of the project is Ross Alexander Burns, a leading guest researcher at the Engineering Research Institute "Ventspils International Radio Astronomy Center" of Ventspils University of Applied Sciences.


Project No. lzp-2022/1-0017 "Multi-Wavelength Study of Quasi-Periodic Pulsations in Solar and Stellar Flares" is intended as a fundamental research study with the main goals of:

  • Using VSRC instruments to establish a reliable and systematic observation system for solar flares and stellar super-flares;
  • Discovering similarities and differences between the radio emission mechanisms of solar and stellar flares and their quasi-periodic pulsation characteristics;
  • Laying the groundwork for future research in collaboration with radio observatories worldwide.


The research program of the project focuses on the extensive study of the quasi-periodic pulsation (QPP) phenomenon (as an indicator of plasma oscillation dynamics) in solar flares and stellar super-flares. Multi-frequency radio astronomical observations are planned in collaboration with colleagues from the University of Warwick (United Kingdom), using the Ventspils International Radio Astronomy Center (VIRAC) complex in Irbene. The research will focus not only on solar flares but also on widely distributed and actively flaring red dwarf stars. QPP detection and analysis in light curves will be performed by combining traditional and innovative data analysis methods, such as wavelet and empirical mode decomposition analysis. Participants from the United Kingdom, with extensive experience in coronal process research, will provide process modeling and lead data analysis.


The project includes the following tasks:

  • Establish a single-baseline interferometer (using both Irbene radio telescopes RT-16 and RT-32) to conduct a research program on solar and stellar flare observations in the radio frequency band.
  • Create and optimize a set of data analysis tools to describe flare light curves and spectra, and to detect QPP events.
  • Discover similarities and differences between solar and stellar flares in their QPP characteristics, and create a comprehensive statistical overview of flares.
  • Present scientific results by publishing them in prestigious, peer-reviewed scientific journals, giving presentations at international and local conferences, holding an annual international seminar on the project topic, participating in public lectures, and preparing a popular science article.
  • Conduct educational work with school students and university students at the VIZIUM Science and Innovation Center (in Ventspils, Latvia).


The expected results during the project implementation will enable VIRAC to establish a unique research cluster capable of conducting world-class solar flare and stellar super-flare observations and data analysis, complementing the capabilities of the world's leading solar research institutes. A particularly interesting and notable phenomenon characteristic of both solar and stellar flares is QPP in the radio frequency bands, which will be used to identify similarities and differences between solar flares and stellar super-flares, as well as their physical mechanisms.


The project activities are planned to be implemented from January 1, 2023, to December 31, 2025. The total project funding is 300,000.00 euros, and the scientific leader of the project is Valeri Nakariakov, a leading guest researcher at the Engineering Research Institute "Ventspils International Radio Astronomy Center" of Ventspils University of Applied Sciences.

"Beyond Words" CoLab and Conference Highlights the Evolving Role of Language and Communication in Modern Society

By Rota Rulle • October 13, 2025
On October 9 and 10, at Ventspils University of Applied Sciences, in cooperation with Jan Dlugosz University in Poland, CoLab “More Than Words: (Inter)Linguistic Aspects in a Practical Context” took place. During the forum, participants discussed topics such as the interaction between language and technology, the impact of artificial intelligence on translation, cultural and identity aspects, current issues in language policy, and the challenges of communication in a multilingual society. Keynote lectures were delivered by speakers from several countries - Ramunė Kasperė from Lithuania, who outlined the future prospects of the translator’s profession in the age of artificial intelligence; Andrejs Veisbergs from the University of Latvia, who addressed issues of censorship in Latvian literary translations; and Olga Słabońska from Poland, who analyzed the grammatical structures of Polish and English from a cognitive perspective. Forum participants were eager to explore current topics from the perspectives of different lecturers and to gain valuable insights, which encouraged a broader understanding of the role of language, culture, and communication in contemporary society. At the end of the first day, all interested participants had the opportunity to visit the Ventspils Open-Air Museum to explore Latvia’s national cultural heritage – the Livonian language – together with Dženeta Marinska, a speaker of Livonian. The lecture concluded with a crossword activity, where participants searched for Livonian names of everyday objects around the museum grounds, followed by a tasting of traditional sklandrauši and smoked flounder from Kolka.  “The Livonian language lecture was truly inspiring – Dženeta spoke about both the history of the Livonian language and her personal journey of learning it. During the lecture, we also listened to Livonian folk songs and experienced the unique sound of the language. This experience made me reflect on the value and fragility of our own language – how easily it could disappear if we do not protect and use it in our daily lives,” shared participant Lelde Bērziņa. As part of the forum, COLOURS Alliance student workshops were also held, where students worked on practical tasks related to digital translation tools, intercultural communication, and foreign language learning. The forum concluded with a panel discussion titled “The Humanities: New Trends, Changes, and the Future.” More photos are available here: https://zviedrans.lv/klientiem/ Beyond Words: (Inter)Lingual Reflections in Practice October 9-10 | Ventspils, Latvia Password: beyondwordsventspils

Astronomers ‘image’ a mysterious dark object in the distant Universe

By Rota Rulle • October 13, 2025
A wide US – Europe network of radio telescopes including observing a faraway radio galaxy discovers a small dark object. It is just a pinch in their data but it signifies that low-mass dark matter clumps are widespread, verifying theories of the Universe’s structure and evolution. The telescopes used include those of VUAS institute “Ventspils International Radio Astronomy Centre” (VIRAC). An international team of astronomers has found a low mass dark object in the distant Universe, not by directly observing any emitted light, but by detecting its tiny gravitational distortion of the light from another distant galaxy. This mysterious object has a mass of about one million times that of our Sun, and its discovery seems consistent with the current best theory about how galaxies like our own Milky Way formed. “Since we can’t see dark matter objects directly, we instead use very distant galaxies as a backlight to look for the gravitational imprints of such objects.” “Hunting for dark objects that don't seem to emit any light is clearly challenging,” said Dr. Devon Powell at the Max Planck Institute for Astrophysics (MPA) and lead author of the study published in Nature Astronomy. “Since we can’t see them directly, we instead use very distant galaxies as a backlight to look for their gravitational imprints.” Dark matter is an enigmatic form of matter not expected to emit light, yet it is essential to understanding how the rich tapestry of stars and galaxies we see in the night sky evolved. As a fundamental building block of the universe, a key question for astronomers is whether dark matter is smooth or clumpy, as this could reveal what it is made of. As dark matter cannot be seen, its properties can only be determined by observing the gravitational lensing effect, whereby the light from a more distant object is distorted and deflected by the gravity of the dark object, creating a characteristic arc in the processed image. The team used a network of telescopes from around the world, including the Green Bank Telescope (GBT), the Very Long Baseline Array (VLBA) and the European Very Long Baseline Interferometric Network (EVN). The latter includes the VIRAC radio astronomical observatory in Irbene. The data from this international network were correlated at the Joint Institute for VLBI ERIC (JIVE) in the Netherlands, forming an Earth-sized super-telescope that could capture the subtle signals of gravitational lensing by the dark object. They discovered that the object has a mass a million times greater than that of our Sun and is located in a distant region of space, approximately 10 billion light years from Earth, when the universe was only 6.5 billion years old. “From the first high-resolution image, we immediately saw a pinch in the gravitational arc, which is the tell-tale sign that we were onto something.” This is the lowest mass object to be found using this technique, by a factor of about 100. To achieve this level of sensitivity, the team had to create a high-fidelity image of the sky using radio telescopes located around the world. Professor John McKean from the University of Groningen (RuG), the University of Pretoria (UP) and the South African Radio Astronomy Observatory (SARAO), who led the data collection and is the lead author of a companion paper, said: “ From the first high-resolution image, we immediately saw a pinch in the gravitational arc, which is the tell-tale sign that we were onto something. Only another small clump of mass between us and the distant radio galaxy could cause this.” To analyse the massive dataset, the team had to develop new modelling algorithms that could only be run on supercomputers. “The data are so large and complex that we had to develop new numerical approaches to model them. This was not straightforward as it had never been done before,” said Dr Simona Vegetti at MPA. “We expect every galaxy, including our own Milky Way, to be filled with dark matter clumps, but finding them and convincing the community that they exist requires a great deal of number crunching,” she continued. The team applied a special technique called gravitational imaging, which allowed them to ‘see’ the invisible dark matter clump by mapping its gravitational lensing effect against the radio-luminous arc. “We expect every galaxy, including our own Milky Way, to be filled with dark matter clumps” “Given the sensitivity of our data, we were expecting to find at least one dark object, so our discovery is consistent with the so-called ‘cold dark matter theory’ on which much of our understanding of how galaxies form is based,” said Powell. “Having found one, the question now is whether we can find more and whether the numbers will still agree with the models.” The team are now analysing the data further to better understand what the mysterious dark object could be, but they are also looking into other parts of the sky to see if they can find more examples of such low-mass dark objects using the same technique. If they continue to find such mysterious objects in other parts of the universe, and if they really turn out to be completely devoid of stars, then some theories of dark matter may be ruled out.
