Executive Summary of Report from Workshop on Submillimeter and Far-Infrared Laboratory Spectroscopy in Support of Herschel, SOFIA, and ALMA October 19-20, 2006 Pasadena, CA

Astronomers must develop a plan to deal with harmful effect of spectral line confusion on the scientific return from the Herschel Space Observatory, the Stratospheric Observatory for Infrared Astronomy (SOFIA), and the Atacama Large Millimeter Array (ALMA). These major new facilities will open up the submillimeter region of the electromagnetic spectrum by making investigations of unprecedented high sensitivity and angular resolution possible. Much of the scientific interest will be in observations of spectral lines. For observations of the dense regions in which star formation occurs, the youngest stars and the proto- planetary disk material surrounding them possess spectra containing a few molecular species with extremely numerous, relatively strong transitions throughout the submillimeter. These species are likely to present a serious challenge, in as much as their emission will occupy a substantial part of the spectral range available, thus impeding the study of other important species. Thus, the discovery of new species of astrophysical and astrobiological interest will be severely hampered unless the spectral lines from these “weeds” can be removed from the data.

We have identified the most offensive weeds, which include six species plus their isotopically substituted variants. We propose that one (or ideally several) spectroscopic laboratories in the US be equipped with sources and detectors to cover the frequency range up to 2 THz, and that they each be funded to hire personnel to actively engage in a program of measuring the spectra of these weed species over a 2 to 3 year period from the present until the first Herschel data are available. Using a combination of traditional quantum state assignment and novel techniques involving measurement and classification of spectral lines measured at different temperatures, the data necessary to remove the weeds from astronomical spectra can be made available. Ongoing measurement and analysis efforts will be required to complete the process for ALMA, SOFIA and other submillimeter facilities.
