The main goal of Andrew Harris' research is understanding the energetics and physical conditions within galaxies and their nuclei. Part of this effort involves developing instrumentation for submillimeter observations over wide bandwidths on the SOFIA and Caltech Submillimeter observatories, and ultra-wideband spectrometers for millimeter wave searches for spectral lines from high redshift sources.An additional application of the spectrometer technology developed within the Laboratory for Millimeter-wave Astronomy is observations of the Earth's own atmospheric spectral lines that enables correction of atmospheric phase effects on millimeter-wave imaging; the millimeter-wave equivalent of active optics. |
