Abstract

Many of the most astrophysically important transitions of atoms and molecules occur at THz frequencies. These transitions allow us to probe the formation and evolution of stars, planets, galaxies, and even the Universe itself. A recent confluence of technologies involving mixers, local oscillators, micromachining, IF amplifiers, and digital signal processing now make the fabrication of large format (~1000 pixel), heterodyne arrays at THz frequencies possible. Planned observatories at high altitude sites (e.g. the high Atacama and Dome A in Antarctica) and in the stratosphere (e.g. SOFIA and balloon-borne telescopes) can serve as platforms from which THz arrays can provide unprecedented access to a powerful window to the Universe. In this paper the scientific impact and technical roadmap to the realization and implementation of THz arrays will be discussed.
