Triple

Target class: very long baseline interferometry array
Context triple: [European VLBI Network, instanceOf, very long baseline interferometry array]

• A. long-baseline interferometer
  A long-baseline interferometer is an instrument that combines signals from widely separated telescopes or antennas to achieve the resolving power of a much larger aperture for high-precision measurements and imaging.
• B. radio interferometer observatory chosen
  A radio interferometer observatory is a facility that combines signals from multiple spatially separated radio antennas to synthesize a much larger effective telescope for high-resolution observations of celestial radio sources.
• C. intensity interferometry effect
  The intensity interferometry effect is the phenomenon where correlations in the intensity fluctuations of light (or other waves) measured at separated detectors reveal information about the spatial structure and coherence properties of the source.
• D. millimeter-wavelength telescope
  A millimeter-wavelength telescope is an astronomical instrument designed to collect and focus electromagnetic radiation in the millimeter band, enabling observations of cold cosmic objects such as molecular clouds, star-forming regions, and the cosmic microwave background.
• E. single-dish telescope
  A single-dish telescope is an observational instrument that uses one continuous, typically parabolic, collecting surface to gather and focus electromagnetic radiation from astronomical sources.
• F. None of above.
