  2. 1. Observations of young core collapse supernova remnants

    Author : Anestis Tziamtzis; Lundqvist Peter; Sergey Zharikov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supernova remnants; Crab; SN 1987A; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : Studies of young remnants offer an opportunity to test theoretical models of stellar evolution, explosion models and nucleosynthesis, as well as our understanding of the compact objects in the centre of the exploded stars.The first part of the thesis involves observations of the Crab nebula.

  4. 2. Facets of Fun: On the Design of Computer Augmented Entertainment Artifacts

    Author : Sus Lundgren; Chalmers tekniska högskola; []
    Keywords : HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; game mechanics; animal expression transfer; Game Design Patterns; the Iron Horse; design tools; remnants; slow technology; the Forces-Clashes-Remnants model; clashes; myTHeme; Interactive entertainment artifacts; forces; the Interactive Quilt; MultiMonsterMania; The Hatchery;

    Abstract : This thesis discusses the design of interactive entertaining artifacts such as computer games and computer augmented toys, games and objects. The aim has been to find and/or develop design tools i.e. READ MORE

  5. 3. Molecules at stellar death: from the winds of massive evolved stars to supernova remnants

    Author : Sofia Wallström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stellar mass-loss; supernova remnants; circumstellar matter; IRAS 17163-3907; yellow hypergiant stars; Cassiopeia A;

    Abstract : Massive stars play a key role in the chemical and dust budget of the galaxy, producing heavy elements, molecules, and dust. At the end of their lives they evolve through stages of significant mass-loss which affect the subsequent evolution of the star, including whether or not it will eventually explode as a supernova (SN).

  6. 4. Supernova remnants and their pulsar wind nebulae

    Author : Natalia Lundqvist; Göran Olofsson; Robert Fesen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pulsars; supernovae; ISM; Astronomy; astronomi;

    Abstract : Massive stars die in powerful stellar explosions, so-called supernovae. In most cases, a neutron star or a black hole is expected to form in the center. The ejected material in these explosions expands out into the surroundings for tens of thousands of years, forming a supernova remnant. If a rapidly rotating neutron star, i. READ MORE

  7. 5. Phenomenological Studies on Supersymmetry and the Strong Force

    Author : Peter Skands; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; R-parity violation; Physics; beam remnants; hadronisation; parton showers; underlying event; Supersymmetry; Fysik; QCD; Fysicumarkivet A:2004:Skands;

    Abstract : In this thesis, we first consider the phenomenology of R-parity violating supersymmetric extensions of the Standard Model. Specifically, a large number of Lepton and Baryon Number violating decays of sparticles to particles are implemented in the Pythia event generator. READ MORE
