Array for Microwave Background Anisotropy

An array for microwave background anisotropy is a set of specialized antennas designed to detect tiny temperature variations in the cosmic microwave background—the faint radiation leftover from the early universe. These arrays collect and analyze microwave signals from different directions in the sky, helping scientists map and understand the universe's initial conditions, structure, and evolution. By precisely measuring these small fluctuations, researchers gain insights into fundamental cosmological parameters and the origins of cosmic structures.
