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.

Ventspils Radio Astronomers Introduce Artificial Intelligence Methods into Their Research

By Rota Žagare • September 11, 2026
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. This information has been prepared within the framework of the project “Ventspils University of Applied Sciences` International Cooperation and Innovation for the Development of Latvia’s Smart Specialisation ” (Project No. 1.1.1.5/3/25/I/012).

Ventspils Researchers Present Latest Discoveries on Massive Star Birth at International Astrophysics Symposium in Germany

By Rota Žagare • August 31, 2026
Dr. Artis Aberfelds, Senior Researcher at the Engineering Research Institute "Ventspils International Radio Astronomy Centre" (VIRAC) of Ventspils University of Applied Sciences, participated in the prestigious international symposium "SFB 1601: Cologne-Bonn Symposium on the habitats of massive stars across cosmic time" held at the University of Cologne, Germany. A scientific report on methanol maser activity around forming massive stars was presented during the event. Organized by the University of Cologne, the symposium brought together leading astrophysicists and radio astronomers from around the world to discuss the latest discoveries in star formation, the interstellar medium, and the physical processes governing the birth of stars. The research presented by Dr. Aberfelds was developed in close international collaboration with researchers A. Sanna and L. Moscadelli from the Italian National Institute for Astrophysics (INAF). Utilizing the Karl G. Jansky Very Large Array (VLA) in the USA – one of the world's most sensitive radio telescope arrays – the study analyzed the connection between 6.7 GHz methanol (CH3OH) maser emission, stellar radiation, and outflows from young massive stars. Key Findings and Conclusions: Discovery of 5 new maser sources: Observing 22 star-forming regions, 6.7 GHz methanol maser emission was detected in 13 objects, revealing 5 previously unknown maser sources. Precise indicator of stellar location: Over 90% of all detected maser spots are located in close proximity to the central star. Direct link with thermal free-free radio continuum emission: The study revealed a strong correlation between methanol maser luminosity and thermal radio emission, enabling astronomers to more accurately predict and identify weak radiation sources in the Universe in the future. Potential for next-generation radio telescopes: Calculations indicate that more than 30% of the methanol maser population currently remains undetected due to sensitivity limits of existing instruments. These sources will be unlocked by next-generation radio interferometers (such as the ngVLA and SKA). The research and conference participation were carried out within the framework of the Latvian Council of Science (LZP) Fundamental and Applied Research Project „Revealing the physical mechanism of mass ejection around young massive stars via CH3OH masers” (Project No. 1.1.1.9/LZP/1/24/044).

Accomplishments of the Project "Modernization of the Irbene Radiotelescope Complex Phase 4"

By Rota Žagare • July 20, 2026
The Engineering Research Institute "Ventspils International Radio Astronomy Centre" (VIRAC) of Ventspils University of Applied Sciences (VUAS) continues to develop its research infrastructure by implementing the project "Modernization of the Irbene Radiotelescope Complex Phase 4" (Project No. 1.1.1.2/1/25/I/005), funded by the European Regional Development Fund (ERDF) with co-financing from the Latvian state budget. The goal of the project is to enhance VIRAC as a centre of excellence of national importance with modern and sustainable scientific infrastructure. Several significant procurements and activities have been carried out as part of the project. To ensure the storage of large volumes of radio astronomy observation data, new hard drives with double the capacity were purchased using project funding for the Irbene Flexbuff data server. The Flexbuff server is used to store radio astronomy observation (typically VLBI) data. The previous data storage capacity was no longer sufficient, as both the transmission speed of observation data and the overall data volume have grown significantly in recent years. The new drives will ensure compliance with the increasing storage requirements of the EVN and CERN Tier-2. A contract has been concluded for the procurement of a six-wheeled ATV (quad bike) and its equipment. Such a mobile vehicle makes it possible to transport and test antenna, mobile satellite communication, unmanned, and floating equipment control and immunity solutions in motion. The vehicle is capable of transporting and testing research equipment in motion across the antenna complex's territory of more than 70 hectares, including forest and marsh conditions. Providing such equipment is essential for the developed systems to reach a high Technology Readiness Level (TRL) under real-world conditions. The engineering systems developed as a result of the research and tested with this vehicle have high dual-use potential. In May 2026, a MIG/MAG semi-automatic welding machine with the necessary peripherals and a set of materials suitable for welding aluminum and its alloys was purchased. The equipment is required for manufacturing feed systems for the RT-32 and RT-16 radio telescopes in order to expand their reception bands and promote new radio astronomical observations. As part of the modernization project, a procurement for the photogrammetry and alignment of the RT-32 radio telescope antenna surface will soon be concluded to improve surface accuracy, sensitivity, and performance at higher frequencies. Currently, the efficiency of the RT-32 antenna reaches only 35–38%, and in the highest frequency bands, it is even lower, making observations practically impossible. Photogrammetric measurements will make it possible to precisely determine the necessary position corrections for each primary mirror panel and adjust the panel mountings accordingly, reducing antenna surface error. Following the antenna surface alignment, the sensitivity, measurement accuracy, and observation capabilities of the radio telescope will improve significantly across all operating frequency bands. Taking into account that on December 15, 2025, a positive decision was received from the European Commission regarding amendments to the European Union Cohesion Policy Programme for 2021–2027, granting flexibility funding for its implementation, contract amendments for the project "Modernization of the Irbene Radiotelescope Complex Phase 4" were signed in July of this year. An additional EUR 79,151 was allocated, of which 85% is ERDF funding and 15% is Latvian state budget co-financing. With the additional funding granted, further procurements are planned within the project for the development of VIRAC's research infrastructure: purchase and installation of spare asynchronous electric motors and their control systems required to ensure the sustainability of the motor drives for the RT-32 and RT-16 radio telescopes; purchase of systems necessary to ensure the sustainability of the RF chain and control systems for the RT-32 and RT-16 radio telescopes; and the purchase of a portable handheld vector network analyzer with a bandwidth of at least up to 26.5 GHz. The EU financial support received under the project "Modernization of the Irbene Radiotelescope Complex Phase 4" (No. 1.1.1.2/1/25/I/005) strengthens VIRAC's capacity to conduct high-quality radio astronomical observations and develop new, dual-use research competencies, while ensuring the sustainability and international competitiveness of the Irbene Radiotelescope Complex.
