  2. 1. Molecular gas in the galaxy M83 : Its distribution, kinematics, and relation to star formation

    Author : Andreas Andersson Lundgren; Hans Olofsson; John Whiteoak; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular gas; Galaxies; Galaxies individual: M83; Star formation; Galactic dynamics; Astronomy and astrophysics; Astronomi och astrofysik;

    Abstract : The barred spiral galaxy M83 (NGC5236) has been observed in the 12CO J=1–0 and J=2–1 millimetre lines with the Swedish-ESO Submillimetre Telescope (SEST). The sizes of the CO maps are 100×100, and they cover the entire optical disk. The CO emission is strongly peaked toward the nucleus. READ MORE

  4. 2. Young Star Clusters and Clumps in the Local Universe : The effect of galactic environment on star formation

    Author : Matteo Messa; Angela Adamo; Göran Östlin; Steven Longmore; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galaxies; Star formation; Star clusters; Astronomy; astronomi;

    Abstract : Stars do not form in isolation, but rather out of a hierarchical structure set by the turbulence of the interstellar medium. At the densest peak of the gas distribution, the star formation process can produce young star clusters (YSCs), which are gravitationally bound systems of stars with mass between ~100 and 106 MSun and typical size of few parsecs.

  6. 4. Star Formation and feedback at key physical scales for galaxy evolution

    Author : Lorenza Della Bruna; Angela Adamo; Göran Östlin; Monica Relaño Pastor; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galaxies; Star Formation; Stellar Feedback; HII regions; ISM; Astronomy; astronomi;

    Abstract : Feedback from young, massive stars plays an essential role in the self-regulation of star formation in galaxies, and in shaping the galaxies' global properties. This phenomenon originates at small scales, surrounding the stars, but has been observed to be effective up to galactic-wide scales. READ MORE
