  1. 11. Molecular Clouds in Starburst Galaxies

    Författare :Susanne Aalto; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Starbursts in the centres of galaxies are believed to be caused by funneling of gas towards the inner regions. Gravitational interactions between galaxies are known to cause vast rearrangements of their structure as well as induce bursts of star formation in their nuclear regions. LÄS MER

  3. 12. Super Star Clusters in Blue Compact Galaxies : Evidence for a near-infrared flux excess and properties of the starburst phase

    Författare :Angela Adamo; Göran Östlin; Erik Zackrisson; Richard de Grjis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; starburst galaxy-extragalactic star clusters-dwarf merger; Astronomy and astrophysics; Astronomi och astrofysik; Astronomy; astronomi;

    Sammanfattning : Luminous Blue compact galaxies (BCGs) are metal-poor actively star-forming systems, characterised by bright ultraviolet and blue luminosities. Hubble Space Telescope high-resolution data have revealed that the luminous star-forming knots in these galaxies are composed of hundreds of young massive star clusters. LÄS MER

  4. 13. A study of the Hercules dwarf spheroidal galaxy

    Författare :Daniel Adén; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Parts of large spiral galaxies, such as the Milky Way and Andromeda, are believed to have formed from the accretion of several smaller galaxies. Remnants of this chaotic merging era, such as dwarf spheroidal (dSph) galaxies, are visible in the outskirts of large galaxies. LÄS MER

  5. 14. A study of the new dwarf spheroidal galaxy in Hercules - metallicity and a stellar inventory

    Författare :Daniel Adén; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Not available.... LÄS MER

  7. 15. Beam mode : Modelling optical systematics in the search for CMB B-mode polarisation

    Författare :Alexandre Adler; Jón E. Gudmundsson; Daniel Mortlock; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : .... LÄS MER
