Science with ALMA
The Atacama Large Millimeter/submillimeter Array (ALMA) will be the forefront instrument for studying the cool universe - the relic radiation of the Big Bang, and the molecular gas and dust that constitute the very building blocks of stars, planetary systems, galaxies, and life itself. This material typically resides at temperatures of 3-100 K, resulting in spectral energy distributions peaking at submillimeter through to far-infrared wavelengths.
Most of the energy in the Universe lies in two thermal components - the cosmic background and the far infrared background - whose Earth-accessible spectrum lies within the ALMA frequency coverage. Indeed, the peak of the spectral energy distribution for dusty objects in the distant universe becomes redshifted entirely to submillimeter wavelengths. While a number of current and future telescopes will operate at submillimeter wavelengths in order to exploit the wealth of information available in this part of the electromagnetic spectrum, none will have the combination of sensitivity, resolution, and frequency coverage of ALMA.
