متن کاملHCl absorption toward Sagittarius B2.
We have detected the 626 GHz J = 1 --> 0 transition of hydrogen chloride (H35Cl) in absorption against the dust continuum emission of the molecular cloud Sagittarius B2. The observed line shape is consistent with the blending of the three hyperfine components of this transition by the velocity profile of Sgr B2 observed in other species. The apparent optical depth of the line is tau approxima...
متن کاملWarm Water Vapor around Sagittarius B2
In the region of Sgr B2 there are several condensations heated externally by nearby hot stars. Therefore H2O far–IR lines are expected to probe only an external low–density and high temperature section of these condensations, whereas millimeter-wave lines can penetrate deeper into them where the density is higher and Tk lower. We have conducted a study combining H2O lines in both spectral regio...
متن کاملFar–IR spectroscopy towards Sagittarius B2
The far–IR is a unique wavelength range for Astrophysical studies, however, it can only be fully sampled from space platforms. The fundamental rotational transitions of light molecules, the high–J transitions of polyatomic species, the bending modes of non-polar molecules, several atomic fine structure lines and many frequencies blocked by the earth atmosphere can only be observed between 50 an...
متن کاملRadiative Transfer Modeling of Lunar Hyperspectral Data
Introduction: One of the current goals of the Selenoligcal and Engineering Explorer “KAGUYA” (SELENE) and the Moon Mineralogy Mapper (M, aboard Chadrayaan-1) missions is the accurate determination of surface composition. These data are being collected with the knowledge that when light interacts with an airless body surface it is either absorbed or reflected in a way unique to each of the most ...
