Scientific paper

WASP (the Wideband Analogue Autocorrelation SPectrometer) is a back-end spectrometer optimized for observations of wide molecular and atomic spectral lines. With 98 spectral channels covering an instantaneous bandwidth of 3.2 GHz at 33 MHz resolution, WASP matches the bandwidth and resolution requirements of both high redshift millimetre and submillimetre-wave line searches and submillimetre-wave studies of molecular gas in extragalactic nuclei. We are now using a first-generation WASP at the Caltech Submillimeter Observatory, and we will build a next-generation WASP for use with the Caltech Submillimeter and Far-Infrared Heterodyne Receiver on SOFIA. This combination of wide-band front and back-ends will make possible velocity-resolved observations of THz-frequency atomic and molecular lines to probe the dynamics and physical conditions of neutral gas within extragalactic nuclei.
