Promotors

The Global VLBI Alliance is open to every VLBI network, at this moment the members are:

• The European VLBI Network (EVN): http://www.evlbi.org/ 
• The East-Asian VLBI Network (EAVN), comprised of the Chinese VLBI Network (CVN), Korean VLBI Network (KVN) and Japanese VLBI Exploration by Radio Astronomy (VERA), the last two also operating together as KaVa: https://radio.kasi.re.kr/eavn/ 
• The Very Long Baseline Array (VLBA) in USA: https://science.nrao.edu/facilities/vlba 
• The southern hemisphere Long Baseline Array (LBA), with radio telescopes in Australia and South Africa: https://www.atnf.csiro.au/vlbi/overview/index.html 

The Global Millimeter VLBI Array (GMVA) is an observer in the GVA.

Note: The joint operation of the EVN and VLBA has historically been known also as “global VLBI”.

 

 

The structure of the Global VLBI Alliance is:

• GVA Director´s Forum (GVAD): VLBI network directors or representatives (up to 2 per network) to discuss any aspect of the global cooperation.
• Science Forum (GVAS): evaluates and fosters the unique and complementary contribution of VLBI to astrophysical research. Members are active scientists, not necessarily linked to any of the VLBI networks in the GVA.
• Technical R&D Forum (GVAT): discusses opportunities and coordinates the development of new instrumentation or procedures,
• Operations and Logistics Team (GVAO): facilitates and coordinates observations scheduled with several VLBI networks, or with participation of third-party instruments (e.g. multi-wavelength/multi-messenger).
• Communication and outreach Team (GVAC): coordinates activities and tools to increase the scientific and societal impact of VLBI.

The GVAS, GVAT, GVAO and GVAC, all report to the GVAD.
