Comparative chemistry of diffuse clouds V. Ammonia and formaldehyde
Using the VLA and NRAO 140′ telescopes we observed the λ1.3 cm (1, 1) and (2, 2) lines of NH3 in absorption and emission toward the compact extragalactic continuum sources NRAO150 (B0355+508) and 3C 111 (B0415+379). These sources are occulted by some seven local diffuse and translucent clouds showing molecular absorption in OH, CO, HCO and C2H: for the four features having NH3 absorption, we fi...
متن کاملA Search for H2CO 6cm Emission toward Young Stellar Objects III: VLA Observations
We report the results of our third survey for formaldehyde (H2CO) 6 cm maser emission in the Galaxy. Using the Very Large Array, we detected two new H2CO maser sources (G23.01−0.41 and G25.83−0.18), thus increasing the sample of known H2CO maser regions in the Galaxy to seven. We review the characteristics of the G23.01−0.41 and G25.83−0.18 star forming regions. The H2CO masers in G23.01−0.41 a...
متن کاملTowards validation of ammonia (NH3) measurements from the IASI satellite
Limited availability of ammonia (NH3) observations is currently a barrier for effective monitoring of the nitrogen cycle. It prevents a full understanding of the atmospheric processes in which this trace gas is involved and therefore impedes determining its related budgets. Since the end of 2007, the Infrared Atmospheric Sounding Interferometer (IASI) satellite has been observing NH3 from space...
متن کاملthe CO, HCN, H2O and H2CO molecules.
Detailed semi-empirical interaction potential calculations are performed to determine the potential energy surface experienced by the molecules CO, HCN, H2O and H2CO, when adsorbed on the basal plane (0001) of graphite at low temperature. The potential energy surface is used to find the equilibrium site and configuration of a molecule on the surface and its corresponding adsorption energy. The ...
متن کاملObservations on “Nonradiating Surface Sources”
The proof, established in a recent paper (A.J. Devaney, “Nonradiating surface sources”, J. Opt. Soc. Am. A, Vol. 21, 2216-2222, 2004), of existence of nonradiating surface sources formed by singlet plus doublet components whose generated fields vanish in either of the regions separated by a closed or infinite surface where the source resides is corroborated by means of an equivalent but slightl...
