In February of this year, the European Union-funded project “Opticon RadioNet Pilot” No 101004719 (ORP) was successfully concluded at the Ventspils International Radio Astronomy Center (VIRAC), part of Ventspils University of Applied Sciences, located in Irbene, Latvia. VIRAC is known for its two large radio telescopes – including a 32-meter dish, one of the largest in Northern Europe – which are used to study radio signals from cosmic objects. Given the scale and complexity of space, collaboration has always been essential, and VIRAC has long been involved in international and EU-funded projects. Since 2009, VIRAC has participated in a series of projects under the “RadioNet” umbrella, aimed at strengthening radio astronomy research across Europe by increasing access to facilities, advancing technology, encouraging institutional collaboration, and supporting the growth of young scientists. The ORP project represented the next step, merging the efforts of radio and optical telescope communities into a single coordinated program. By integrating facilities observing across the radio, sub-mm, infrared, and optical wavebands, ORP enabled seamless access for European researchers to an unparalleled array of observatories. With a total budget of €15 million, of which €60,000 was allocated to VIRAC and Ventspils University, the project supported VIRAC’s active participation in multiple scientific and collaborative activities. Among these activities, VIRAC regularly participates in EVN (European VLBI Network) observation sessions, held three times a year, as well as in monthly real-time e-VLBI sessions and EVN-lite observations, which serve as supplementary components to the main EVN observation programme. Participation in these activities has been actively supported and facilitated through the ORP (Opticon RadioNet Pilot) project. Additionally, VIRAC researchers are actively involved in the international scientific community, regularly attending major conferences and participating in training programs and exchange visits at leading European observatories. Activities such as transnational access to European ESFRI and ERIC research facilities, training programs, and support for the astronomical community will continue through one of the most significant outcomes of the ORP project—ACME (Astrophysics Centre for Multi-Messenger Studies in Europe). This new initiative aims to integrate not only optical and radio astronomy but also other branches of astrophysical observation, including gravitational waves, neutrinos, and cosmic rays, fostering a truly multi-messenger approach to astronomy. This project has received funding from the European Union's research and innovation programme HORIZON 2020 under grant agreement No 101004719.
