We propose 3 by 5 point maps of [OI] (63 microns) and [CII] (158 microns) emission, measurement of the [FeI] (24 microns), [SI] (25 microns), [FeII] (26 microns), [SiII] (35 microns), OH (119 microns), [OI] (146 microns), and CO J=14-13 (186 microns) lines, and the 40-196 micron continuum spectrum at the central position of the X-ray source 1E1740.7-2942. This is the purported compact, variable source of gamma-ray annihilation emission in the galactic center region. The purpose of these measurements is to determine whether 1E1740.7-2942 is embedded within a molecular cloud, and to test whether Bondi-Hoyle accretion onto an isolated compact object could power the observed X-ray and gamma-ray emission. We will accomplish this by probing the effect of the 1-100 keV X-rays on the molecular gas through measurement of the gas temperature, density, and chemical abundances. These measurements will also probe whether a significant fraction of the positrons produced by the source escape the vicinity to power the steady, bulge component of the gamma-ray annihilation emission observed from the galactic center.
