The Atacama Cosmology Telescope collaboration, which includes scientists from NIST, Unveils New Map of Dark Matter | NIST

The Atacama Cosmology Telescope (ACT) collaboration, including scientists from NIST, has released the most detailed map yet of dark matter distribution across a quarter of the sky and far back in time. Dark matter, believed to make up 85% of the universe’s mass, provides the gravitational structure that holds galaxies together.

Researchers from NIST’s Quantum Sensors Group designed and built four specialized sensor arrays for ACT’s camera. These sensors operate at extremely low temperatures and require advanced multiplexed superconducting electronics to read. The new map supports Einstein’s theory of general relativity and offers new methods to study dark matter’s nature, which remains a mystery.
