Abstract

The Stratospheric Terahertz Observatory (STO) is a long-duration balloon (LDB) experiment designed to address a key problem in modern astrophysics. STO is a collaborative effort led by the University of Arizona and APL with a significant contribution from the JHU Department of Physics and Astronomy. It is a balloon-borne observing platform that will carry an 80-cm-aperture telescope in the stratosphere at an altitude of ̃120,000 feet. The telescope will feed a heterodyne receiver consisting of eight phonon-cooled hot-electron bolometer (HEB) mixers, optimized for the dominant interstellar cooling line [CII].
