The Excitation of Molecular Clouds and the Emission from Molecular Hydrogen
نویسنده
چکیده
The observation and theory of UV{excitation of molecular clouds (i.e., photodissociation regions) and the shock-excitation of molecular clouds is reviewed, with particular emphasis placed on the emission from molecular hydrogen. Recent advances in near{IR instrumentation have engendered new observations which are challenging our theoretical understanding of these fundamental physical processes. Subject headings: molecular processes { shock waves { infrared: spectra { interstellar: molecules { interstellar: grains { interstellar: magnetic elds { nebulae: general { nebulae: Orion

Organic matter from biofilter nitrification by high performance size exclusion chromatography and fluorescence excitation-emission matrix
A combination of high performance size exclusion chromatography with organic carbon detector and ultraviolet detector coupled with peak-fitting technique and fluorescence excitation-emission matrix spectrometry applied fluorescence regional integration method was conducted to determine the characteristics of organic matter during nitrification. The batch scale of bionet nitrification without or...
متن کاملDetections of Molecular Hydrogen in the Outer Filaments of NGC 1275
We present clear spectroscopic detections of molecular hydrogen in the outer filaments of the Hα nebula surrounding the central galaxy of the Perseus cluster, NGC 1275. This implies the presence of warm molecular gas clouds at projected distances up to 24 kpc from the nucleus of the host galaxy, embedded in the hot intracluster medium. The emission-line intensity ratios reveal that the H2 emiss...
متن کاملNICMOS Imaging of Molecular Hydrogen Emission in Seyfert Galaxies
We present NICMOS imaging of broad band and molecular hydrogen emission in Seyfert galaxies. In 6/10 Seyferts we detect resolved or extended emission in the 1-0 S(1)λ2.121μm or 1-0 S(3)λ1.9570μm molecular hydrogen lines. We did not detect emission in the most distant galaxy or in the 2 Seyfert 1 galaxies in our sample because of the luminosity of the nuclear point sources. In NGC 5643, NGC 2110...
متن کاملLaboratory evidence for the non-detection of excited nascent H2 in dark clouds
There has always been a great deal of interest in the formation of H2 as well as in the binding energy released upon its formation on the surface of dust grains. The present work aims at collecting experimental evidence for how the bond energy budget of H2 is distributed between the reaction site and the internal energy of the molecule. So far, the non-detection of excited nascent H2 in dense q...
