    Abstract : Eta Carinae is a super-massive, super-luminous star. It is surrounded by a bipolar nebula, the "Homunculus", and several blobs of ejected gas which are the source of a complex emission-line spectrum. READ MORE

  4. 2. Search for Gamma-ray Lines from Dark Matter with the Fermi Large Area Telescope

    Author : Tomi Ylinen; Mark Pearce; Jan Conrad; Staffan Carius; James T. Linnemann; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fermi; Large Area Telescope; gamma-rays; dark matter; spectral lines; beam test; Physics; Fysik; Astroparticle physics; Astropartikelfysik;

    Abstract : Dark matter (DM) constitutes one of the most intriguing but so far unresolved issues in physics. In many extensions of the Standard Model of particle physics, the existence of a stable Weakly Interacting Massive Particle (WIMP) is predicted. The WIMP is an excellent DM particle candidate.

  6. 4. Search for low mass WIMPs with the AMANDA neutrino telescope

    Author : Anna Davour; Olga Botner; Carlos de los Heros; Mark Pearce; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; dark matter; WIMP; neutrino detection; AMANDA; supersymmetry; Fysik; Physics; Fysik; High Energy Physics; Högenergifysik;

    Abstract : Recent measurements show that dark matter makes up at least one fifth of the total energy density of the Universe. The nature of the dark matter is one of the biggest mysteries in current particle physics and cosmology. READ MORE

  7. 5. Bright Needles in a Haystack : A Search for Magnetic Monopoles Using the IceCube Neutrino Observatory

    Author : Alexander Burgman; Carlos Pérez de los Heros; Olga Botner; Allan Hallgren; David Milstead; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; magnetic monopole; IceCube; astroparticle physics; neutrino telescope; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : The IceCube Neutrino Observatory at the geographic South Pole is designed to detect the light produced by the daughter-particles of in-ice neutrino-nucleon interactions, using one cubic kilometer of ice instrumented with more than 5000 optical sensors.Magnetic monopoles are hypothetical particles with non-zero magnetic charge, predicted to exist in many extensions of the Standard Model of particle physics.
