  1. 1. Constraints on the Kaluza-Klein Photon as a Dark Matter Candidate from the IceCube Collaboration Results

    University essay from Uppsala universitet/Högenergifysik

    Author : Miquel Colom i Bernadich; [2019]
    Keywords : dark matter; WIMP; Kaluza-Klein; IceCube; neutrinos; muon neutrinos; muons;

    Abstract : New constraints on the scattering cross sections of the Kaluza Klein photon as a darkmatter candidate, its annihilation rate in the Sun and the resulting muon flux on Earth are derived.For this purpose, data collected in the IceCube Neutrino Observatory during 532 days of exposurein the austral winters between 2011 and 2014 have been analyzed with Poisson confidence intervals (J.

  3. 2. Probing the effect of dark matter velocity distributions on neutrino-based dark matter detection

    University essay from Uppsala universitet/Högenergifysik

    Author : Martin Ståhl; [2019]
    Keywords : Dark matter; WIMPs; velocity distribution; indirect detection;

    Abstract : Dark matter has a long history, but it was not until modern times that we have a chance of detecting it. This thesis focuses on the velocity distribution and its effect on indirect WIMP detection. Recently a new velocity distribution, based on data from SDSS and GAIA, was proposed. READ MORE

  4. 3. Neutrinos from Dark Matter Annihilation in the Sun

    University essay from KTH/Teoretisk fysik

    Author : Fredrik Hansen; Erik Holmgren; [2013]
    Keywords : Dark Matter; WIMP annihilation; neutrino; the Sun.;

    Abstract : Dark Matter (DM) is believed to consist ofWeakly Interactive Massive Particles (WIMPs) which interact only through gravity and the weak nuclear force. These particles can become trapped in gravitational wells such as the Sun and a theoretical value of the capture rate can be calculated. READ MORE

  5. 4. Dark Matter Signatures in Cosmic Gamma-Rays

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Jonas Wessén; [2012]
    Keywords : gravitino; 130 GeV line; IACT; MAGIC; indirect dark matter detection; decaying dark datter; Physics and Astronomy;

    Abstract : This thesis concentrates on one of the indirect Dark Matter (DM) detection methods, namely through observations of Very High Energy (VHE) $\gamma$-ray signals from DM annihilation (or decay) in cosmic sources using the Imaging Atmospheric Cherenkov Technique (IACT). We discuss the particle physics and astrophysical aspects of those observations and perform several calculations which lead to an estimation of the DM detection prospects for IACTs. READ MORE

  6. 5. The effect of dark matter capture on binary stars

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Daniel Carrera; [2012]
    Keywords : Physics and Astronomy;

    Abstract : WIMPs, orWeakly InteractingMassive Particles, are a popular dark matter candidate, but their detection remains elusive. At its core, this project is an effort to bridge the gap between the theory of WIMPs, and astronomical observation. READ MORE
