High excitation ISM and gas
نویسنده
چکیده
An overview is given of ISO results on regions of high excitation ISM and gas, i.e. H ii regions, the Galactic Centre and Supernovae Remnants. IR emission due to fine-structure lines, molecular hydrogen, silicates, polycyclic aromatic hydrocarbons and dust are summarised, their diagnostic capabilities illustrated and their implications highlighted.

Low-excitation gas in HR 10: possible implications for estimates of metal-rich H2 mass at high redshifts
We examine the physical conditions of the molecular gas in the extremely red object (ERO), HR10 (J164502+4626.4, or [HR94] 10) at z = 1.44, as constrained by the recent detection of CO J + 1 → J, J = 1, 4 lines. The line ratios of such widely spaced CO transitions are very sensitive probes of gas excitation; in the case of HR10, they provide a rare opportunity to study the state of H2 gas in a ...
متن کاملSynthetic Observations of Carbon Lines of Turbulent Flows in Diffuse Multiphase Interstellar Medium
We examine observational characteristics of multi-phase turbulent flows in the diffuse interstellar medium (ISM) using a synthetic radiation field of atomic and molecular lines. We consider the multi-phase ISM which is formed by thermal instability under the irradiation of UV photons with moderate visual extinction AV ∼ 1. Radiation field maps of C, C, and CO line emissions were generated by ca...

Cepheus E is the site of an exceptional example of a protostellar outflow with a very young dynamical age and extremely high near infrared luminosity. We combine molecular spectroscopic data from the submillimeter to the near infrared in order to interpret the rotational excitation of CO and the ro-vibrational excitation of H2. We conclude that C-type shocks with a paraboloidal bow shock geomet...
متن کاملHigh Excitation Molecular Gas in the Magellanic Clouds
We present the first survey of submillimeter CO (J = 4 → 3) emission in the Magellanic Clouds. The survey is comprised of 15 6 × 6 maps obtained using the AST/RO telescope toward the molecular peaks of the Large and Small Magellanic Clouds. We have used these data to constrain the physical conditions in these objects, in particular their molecular gas density and temperature. We find that there...
متن کاملGRB Afterglows as a New ISM and IGM Probe
We summarize results from a study of the metallicity, relative abundances, gas density, and kinematics of dense media in the host environment of two Swift bursts, GRB 050730 at z = 3.968 and GRB 051111 at z = 1.549. Both GRB hosts exhibit strong absorption features from excited Si+ and Fe+ ions, indicating an extreme ISM environment that is similar to what is found around massive stars like lum...
