Cosmology Large Angular Scale Surveyor

The Cosmology Large Angular Scale Surveyor consists of multiple telescopes operating at frequencies between 40 and 220 GHz across the Atacama Desert mountaintop.

The facility initiated observations in 2016 with its Q-band instrument, followed by W-band implementation in 2018 and high-frequency instruments in 2019.

Scientists from multiple research institutions collaborate at this facility to study fundamental aspects of universe formation through cosmic microwave background radiation.

The telescope array captures data from 75 percent of the sky using advanced cryogenic technology to minimize thermal interference in measurements.

The facility measures polarization patterns at a sensitivity of several parts per billion, detecting minute variations in radiation from the early universe.

Elevation above the sea: 5,140 m
