• Alternative coalescence model for deuteron, tritium, helium-3 and their antinuclei 

      Kachelriess, Michael; Ostapchenko, Sergey; Tjemsland, Jonas (Peer reviewed; Journal article, 2020)
      Antideuteron and antihelium nuclei have been proposed as a detection channel for dark matter annihilations and decays in the Milky Way, due to the low astrophysical background expected. To estimate both the signal for ...
    • Antinuclei as a Signature of Dark Matter 

      Tjemsland, Jonas (Master thesis, 2019)
      Antideuteron og antihelium er blitt foreslått som en deteksjonskanal for spalting og annihilasjon av mørk materie i Melkeveien på grunn av en forventet lav astrofysisk bakgrunnstøy. I dag er det vanlig å bruke en standard ...
    • Reacceleration of charged dark matter 

      Kachelriess, Michael; Tjemsland, Jonas (Peer reviewed; Journal article, 2020)
      Charged particles scattering on moving inhomogenities of the magnetised interstellar medium can gain energy through the process of second-order Fermi acceleration. This energy gain depletes in turn the magnetic wave spectrum ...
    • Revisiting cosmic ray antinuclei fluxes with a new coalescence model 

      Kachelriess, Michael; Ostapchenko, Sergey; Tjemsland, Jonas (Peer reviewed; Journal article, 2020)
      Antideuteron and antihelium nuclei have been proposed as promising detection channels for dark matter because of the low astrophysical backgrounds expected. To estimate both potential exotic contributions and their ...
