The Global VLBI Alliance (GVA) has established a Science Forum (GVAS) in order to promote VLBI widely. The GVAS was presented at the recent IAU B4 business meeting on 8 August 2022. The session presented the current and future plans for the main cm-VLBI networks (EVN, EAVN, VLBA, LBA), as well as the VLBI connection with SKA (SKA-VLBI). In the short discussion that followed, some topics are identified as core actions for the GVAS:

  • Identify science cases for GVA, possible preparation of a white paper,
  • Promote and advocate for VLBI in events,
  • Cross-disciplinary collaborations,
  • Assist infrastructure roadmap exercises at national and international level,
  • Assist in communication efforts about VLBI.

Since the GVAS will be organizing the different subcommittees soon, all astronomers are invited to join and participate! Contact us and get involved in the discussions!
