description IRAM 30m Telescope Overview
The IRAM 30m telescope is a ground-based radio observatory situated on Pico Veleta, Spain. It’s notable as the largest single-dish millimeter-wave telescope globally. This instrument allows astronomers to study cool objects in space like molecular clouds and distant galaxies. Researchers utilizing it include those studying star formation, galactic evolution, and the early universe.
help IRAM 30m Telescope FAQ
What wavelengths does the IRAM 30m Telescope observe?
It observes millimeter radio waves over frequencies of roughly 80 to 370 GHz. These wavelengths reveal cold molecular gas, dust, star-forming clouds, and distant galaxies that may be faint in visible light.
Why is the IRAM telescope built on Pico Veleta?
Pico Veleta places the dish about 2,850 meters above sea level in Spain's Sierra Nevada. The high, comparatively dry site reduces atmospheric water vapor, which otherwise absorbs millimeter radiation.
What does the NIKA2 camera do on the IRAM 30m telescope?
NIKA2 is a dual-band continuum camera that produces wide-field maps at millimeter wavelengths and can measure polarization. It became available for regular scientific observations in 2017.
How is the IRAM 30m different from the NOEMA interferometer?
The Pico Veleta instrument is one 30-meter dish and is especially useful for extended emission and spectral surveys. NOEMA combines multiple antennas in the French Alps to deliver the finer angular resolution of an interferometer.
