Remote sensing of planetary properties and biosignatures on extrasolar terrestrial planets.
The major goals of NASA's Terrestrial Planet Finder (TPF) and the European Space Agency's Darwin missions are to detect terrestrial-sized extrasolar planets directly and to seek spectroscopicExpand

The deepest Herschel-PACS far-infrared survey: number counts and infrared luminosity functions from combined PEP/GOODS-H observations
We present results from the deepest Herschel-Photodetector Array Camera and Spectrometer (PACS) far-infrared blank field extragalactic survey, obtained by combining observations of the GreatExpand

PACS Evolutionary Probe (PEP) – a Herschel key program
Deep far-infrared photometric surveys studying galaxy evolution and the nature of the cosmic infrared background are a key strength of the Herschel mission. We describe the scientific motivation forExpand

The Submillimeter Wave Astronomy Satellite: Science Objectives and Instrument Description
The Submillimeter Wave Astronomy Satellite (SWAS), launched in 1998 December, is a NASA mission dedicated to the study of star formation through direct measurements of (1) molecular cloud compositionExpand

Implications of Submillimeter Wave Astronomy Satellite Observations for Interstellar Chemistry and Star Formation
A long-standing prediction of steady state gas-phase chemical theory is that H2O and O2 are important reservoirs of elemental oxygen and major coolants of the interstellar medium. Analysis ofExpand

O-2 in interstellar molecular clouds
We have used the Submillimeter Wave Astronomy Satellite (SWAS) to carry out deep integrations on the NJ = 33 → 12 transition of O2 in a variety of Galactic molecular clouds. We here report noExpand

Observations of Absorption by Water Vapor toward Sagittarius B2
We have observed the 110-101 pure rotational transitions of both H216O and H218O toward Sagittarius B2 using the Submillimeter Wave Astronomy Satellite. The spectra thereby obtained show a complexExpand

Observations of water vapor toward Orion BN/KL
We have obtained spectra of the rotational ground-state 110-101 556.936 GHz ortho-H216O and 110-101 547.676 GHz ortho-H218O transitions toward Orion BN/KL using the Submillimeter Wave AstronomyExpand
