Ventspils University of Applied Sciences Researcher Participates in International Radio Astronomy Workshops in the Netherlands
In September, Matīss Purviņš, a programmer at the Ventspils International Radio Astronomy Centre (VIRAC) at Ventspils University of Applied Sciences, participated in two high-level international workshops – the CASPER Workshop 2025 and the SFXC Workshop 2025 – held in Dwingeloo, the Netherlands.
These workshops brought together radio astronomy experts from around the world to exchange knowledge and experience on cutting-edge technologies, ranging from high-performance computing with GPUs to correlation algorithms and data processing tools.
The CASPER Workshop focused on modern hardware technologies and software tools used in radio astronomy. Participants explored the applications of FPGA (Field-Programmable Gate Arrays) and RFSoC (Radio Frequency System-on-Chip) systems, data transport architectures, and the latest developments within the CASPER tool community. The program also included a guided tour of the Westerbork Synthesis Radio Telescope (WSRT) and LOFAR core stations, offering insights into the technologies in use and their historical evolution.
The SFXC Workshop offered in-depth theoretical lectures and hands-on sessions on correlation processes in radio astronomy. Participants learned about pulsar signal processing, the search for FRBs (Fast Radio Bursts), and geodetic correlation techniques using the SFXC correlator – a specialized software tool for combining data from multiple telescopes.
A highlight of the workshop was the presentation of a GPU-based correlation solution currently under development for future VLBI (Very Long Baseline Interferometry) projects, including the global Square Kilometer Array (SKA) initiative.
Participation in these workshops not only enhanced the professional qualifications of VIRAC staff but also strengthened international collaboration with leading researchers and institutions in the field of radio astronomy.
This experience was made possible through the activities of the JIV-ERIC and LOFAR ERIC consortia and co-financed by the European Regional Development Fund under project No. 1.1.1.5/3/25/I/012 “Ventspils University of Applied Sciences` International Cooperation and Innovation for the Development of Latvia’s Smart Specialisation”.
Radio astronomy technologies continue to evolve rapidly – and Ventspils University of Applied Sciences is proud to be part of this exciting journey.
