Arcminute Microkelvin Imager, Radio interferometer at Mullard Radio Astronomy Observatory, England
The Arcminute Microkelvin Imager is a radio interferometer in Cambridge that uses two separate antenna arrays working together to observe the sky and collect data about distant cosmic structures. The instrument operates by capturing radio waves from space, allowing scientists to study how galaxy clusters form and evolve.
This instrument was developed at Cambridge and incorporates reused components from an earlier radio telescope that operated at the same location. Building on previous technology allowed scientists to create a more capable observatory while making efficient use of existing equipment.
Scientists at the observatory conduct extensive research on galaxy clusters by analyzing secondary variations in the cosmic microwave background through the Sunyaev-Zel'dovich effect.
This is an active research facility located outside the city, and visitors cannot simply walk onto the grounds without prior arrangement. Getting in touch with the observatory staff beforehand is essential to arrange any visit or learn about public access options.
This instrument was specifically designed to detect tiny temperature variations in ancient light from the early universe caused by massive galaxy clusters. These minute differences would be invisible to ordinary equipment, but this telescope can reveal them and provide insights into some of the largest structures in existence.
