  2. 1. Distant supernovae and galaxies in the Stockholm VIMOS Supernova Survey

    Author : Laia Mencia Trinchant; Göran Östlin; Duilia F de Mello; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; imaging surveys; photometric redshfits; Lyman Break galaxies; supernova typing; supernova rates; supernova host galaxies; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : Multi colour imaging surveys help astronomers to find galaxies and clusters,and to gain insights on their physical properties and evolution. In this thesis, I present the Stockholm VIMOS Supernova Survey (SVISS), where the ELAIS-S field was observed with VIMOS UBVRI broad-band optical bands over a period of 5 years. READ MORE

  4. 2. 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.

  5. 3. Supernova surroundings on circumstellar and galactic scales

    Author : Anders Nyholm; Jesper Sollerman; Peter Lundqvist; Philip James; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supernovae; circumstellar medium; SNe Type IIn; iPTF13z; intermediate Palomar Transient Factory; active galactic nuclei; SN 2014J; Astronomy; astronomi;

    Abstract : Some stars cease to be in a bright and destructive display called a supernova. This thesis explores what we can learn about supernovae (SNe) by studying their immediate surroundings, and what the SNe can teach us about their environments. READ MORE

  6. 4. Search for lensed supernovae behind the galaxy cluster Abell 1689

    Author : Tanja Petrushevska; Rahman Amanullah; Ariel Goobar; Peter Lundqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lensed supernovae; gravitational lensing; galaxy cluster Abell 1689; Astronomy; astronomi; fysik; Physics;

    Abstract : Distant supernovae probe the history of cosmic expansion and star formation, and provide important information on their progenitor models. Investigation of supernovae type Ia for  are needed to reveal any evolution in their intrinsic properties, and thus their utility as existing distance indicators. READ MORE
