1. 11. Astrophysical and Collider Signatures of Extra Dimensions

   Författare :Henrik Melbéus; Tommy Ohlsson; Jörn Kersten; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Extra-dimensional quantum field theories; universal extra dimensions; Kaluza-Klein dark matter; Arkani-Hamed-Dimopoulos-Dvali model; hierarchy problem; neutrino mass; seesaw mechanism; Large Hadron Collider phenomenology; Elementary particle physics; Elementarpartikelfysik;

   Sammanfattning : In recent years, there has been a large interest in the subject of extra dimensions in particle physics. In particular, a number of models have been suggested which provide solutions to some of the problems with the current Standard Model of particle physics, and which could be tested in the next generation of high-energy experiments.

3. 12. Delving in the Dark : Searching for Signatures of Non-Standard Physics in Cosmological and Astrophysical Observables

   Författare :Janina J. Renk; Joakim Edsjö; Pat Scott; Felix Kahlhöfer; David F. Mota; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cosmology; gravitation; Galileon; dark energy; dark matter; cosmic superstrings; neutrino mass; parameter inference; teoretisk fysik; Theoretical Physics;

   Sammanfattning : The dark sectors of our Universe, dark matter and dark energy, together constitute about 96 % of the total energy content of the Universe. To date, we only have observational evidence for their existence. LÄS MER

4. 13. The Advanced Spectral Leakage (ASL) scheme for simulations of merging neutron stars

   Författare :Davide Gizzi; Stephan Rosswog; Evan O'Connor; Albino Perego; Carla Fröhlich; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrodynamics; radiative transfer; neutrinos; stars: neutron; supernovae: general; Astronomy; astronomi;

   Sammanfattning : The detection of a blue macronova following the event GW170817 has emphasized the role that neutrinos play in merging neutron stars. In particular, neutrinos are able to drive mass ejection, the so-called neutrino-driven winds, and change the neutron richness of the matter by absorption. LÄS MER

5. 14. Indirect Searches for Galactic Dark Matter with IceCube-DeepCore and PINGU

   Författare :Martin Wolf; Chad Finley; David Milstead; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark Matter; Galactic Center; IceCube; DeepCore; PINGU;

   Sammanfattning : The cubic-kilometer sized IceCube neutrino observatory is burieddeep in the glacial ice at the Earth’s South Pole. Its low-energyextension array DeepCore enables physicists to search indirectlyfor light Dark Matter (DM) particles with masses as low as tensof GeV/c2 situated within our home galaxy, the Milky Way.

7. 15. Dark Matter Phenomenology in Astrophysical Systems

   Författare :Stefan Clementz; Mattias Blennow; Kai Schmidt-Hoberg; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

   Sammanfattning : There is now a great deal of evidence in support of the existence of a large amount of unseen gravitational mass, commonly called dark matter, from observations in astrophysical systems of sizes ranging from that of dwarf galaxies to the scale of the entire Universe. One of the most promising explanations for this unseen mass is that it consists of a species of unobserved elementary particles. LÄS MER
