List of European radio interferometers:

• NOEMA radio observatory
• Westerbork radio observatory
• Northern Cross radio observatory
• LOFAR radio telescope
• MERLIN nodes:
  • Cambridge radio observatory
  • Darnhall radio observatory
  • Defford radio observatory
  • Jodrell Bank radio observatory

Radio observatories participating in VLBI Networks:

• European VLBI network (EVN) are listed here.
• Global mm-VLBI Array (GMVA) are listed here.
• VLBI Global Observing System (VGOS) are listed here (to be added).
• e-Callisto (solar radio monitoring) are listed here.

Notes:

• The MERLIN and Westerbork interferometers also operate in single-dish mode.
• None of these observatories is exclusively dedicated to Very Long Baseline Interferometry (VLBI), but some participate in VLBI sessions.
• Participation in VLBI depends on each observatory’s frequency capabilities; they do not take part in VLBI observations simultaneously.
