  4. 2. Studies of Interstellar Molecular Gas in the Magellanic Clouds

    Author : Arto Heikkilä; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; abundances-Galaxies; evolution; molecules-Galaxies; Magellanic Clouds-Interstellar medium; molecules-Galaxies; interstellar medium-Galaxies;

    Abstract : Results of observational studies of interstellar molecular gas clouds in the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC), two nearby metal-poor and dust-poor dwarf galaxies, are presented. Spectral line radiation emitted by interstellar molecules has been used to probe the physical state and the chemical composition of individual molecular clouds. READ MORE

  5. 3. Observations and analysis of water in molecular outflows and shocks

    Author : Per Bjerkeli; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; interstellar medium; molecules; jets and outflows; pre-main-sequence; stars; supernova remnants;

    Abstract : This thesis describes observations and analysis of molecular outflows from young stellar objects. The observations using the Odin satellite are described in Paper I, where a non-LTE radiative transfer code has been used to estimate the ortho-water abundance in seven molecular outflows and one super-nova remnant.

  7. 5. Molecular Hole Punching : Impulse Driven Reactions in Molecules and Molecular Clusters

    Author : Michael Gatchell; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Joachim Burgdörfer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PAHs; Fullernes; Reactions; Clusters; Interstellar Medium; Fragmentation; Non-Statistical Fragmentation; Collisions; Experiments; Molecular Dynamics; Density Functional Theory; fysik; Physics;

    Abstract : When molecules are excited by photons or energetic particles, they will cool through the emission of photons, electrons, or by fragmenting. Such processes are often thermal as they occur after the excitation energy has been redistributed across all degrees-of-freedom in the system. READ MORE
