  1. 6. The Kinematics of Blue Compact Galaxies - Gas and Stars

    Author : Thomas Marquart; Uppsala universitet; []
    Keywords : ;

    Abstract : Blue Compact Galaxies (BCGs) are intensely star forming, gas-rich systems and their light is dominated by a young stellar population and nebular emission. Their irregular morphology suggests dwarf galaxy mergers as cause for the onset of the burst in star formation. READ MORE

  2. 7. Quasar host galaxies at intermediate and high redshifts

    Author : Eva Örndahl; Bengt Gustafsson; Jari Kotilainen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Active galaxies; Quasars; Host galaxies; Imaging; Photometry; Magnitudes; Colours; Morphology; Statistical methods; High-redshift; Infrared; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; Theoretical Astrophysics; teoretisk astrofysik;

    Abstract : Quasars form one of the most energetic phenomena in the universe, and can be traced out to very large redshifts. By studying the galaxies which host the active nuclei, important insights can be gained into the processes that trigger and maintain the quasar powerhouse. READ MORE

  3. 8. Impact of feedback on the ISM of extreme starburst galaxies : The case of Haro 11

    Author : Veronica Menacho Menacho; Göran Östlin; Armando Gil de Paz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galaxies; stellar feedback; ISM; Integral field spectroscopy; Astronomy; astronomi;

    Abstract : Blue compact galaxies (BCGs) are compact, metal-poor, starbursting galaxies with characteristics similar to what is expected for the young high-redshifted galaxies. BCGs are among the most active in producing a large number of massive star clusters, each containing thousands of massive stars. READ MORE

  4. 9. Modelling the Winds from Carbon Rich AGB Stars : Implications for Stellar Evolution and the Chemical Evolution of Galaxies

    Author : Lars Mattsson; Uppsala universitet; []
    Keywords : ;

    Abstract : Stars on the AGB are known to lose mass at high rates (10-8 - 10-4 Msun/yr) through slow winds (20 km/s), enriching the inter stellar medium with newly synthesised elements. We explore how the mass loss for C-rich AGB stars depends on the basic stellar parameters by computing a large grid of wind models. READ MORE
