Description

Title:Rotationally Excited H2 In The Magellanic Clouds
Author(s):Xue, Rui

Subject(s):Mini-symposium: Astronomical Molecular Spectroscopy in the Age of ALMA
Abstract:We have performed a systematic analysis of excited-state (up to $J$=5) H$_{2}$ Lyman-Werner absorption lines using archival spectra in the {\it FUSE} Magellanic Clouds Legacy Project. The H$_{2}$ column densities at different ground state $J$-levels and the Doppler broadening parameter b are determined for both Magellanic and Galactic components along each line of sight. Combining the results with previously measured total gas column densities of HI and H$_{2}$, we derive the H$_{2}$ excitation temperature, volume density, and local UV field strength for the absorbing gas. The physical and chemical properties of the absorbers are compared with Galactic samples, and also used to test predictions from multiple-phase ISM equilibrium models. Finally, we compare the absorbing gas from the Magellanic Clouds with its larger-scale ISM environment as revealed in previous surveys of gas and dust emission, extending our results from the UV data measured along moderately reddened sight lines to more dense gas detected in emission.
