  2. 1. 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.

  4. 2. Th Dynamics of Star Cluster Formation

    Author : Juan Pablo Farias Osses; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Star Formation; Star Clusters; Stellar Dynamics;

    Abstract : A major question in astrophysics is how star clusters form. These objects are important, since they are the birth sites of most stars, perhaps including our own Sun. READ MORE

  5. 3. Star clusters as engines of galaxy evolution

    Author : Mattia Sirressi; Angela Adamo; Matthew Hayes; Paul Crowther; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extragalactic astronomy; Galaxies; Star formation; Interstellar medium; Stellar feedback; Ultraviolet surveys; Hubble Space Telescope; Spectroscopy; Data analysis; Astronomy; astronomi;

    Abstract : Feedback in star forming galaxies is the key process that regulates how many stars form given the available gas reservoir. The radiation, energy and momentum released by the stellar activity and the active galactic nuclei change the physical properties of the gas in the galaxy such as the ionisation state, the density and the kinematics.

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

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

    Abstract : 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. READ MORE

  7. 5. The Dynamics of Star Cluster Formation

    Author : Juan Pablo Farias Osses; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Star Cluster Formation; Star Formation; N-body simulations; Astronomy Astrophysics;

    Abstract : How do star clusters form? We care, since these are the birth sites of most stars, perhaps including our own Sun. There are a great variety of different theoretical models of cluster formation and our main goal in this thesis is to examine the implications of these for the dynamical evolution of a cluster's stellar population, including the ejected stars.
