The Fermi Bubbles are extended regions of hard gamma-ray emission which
were discovered with Fermi-LAT data to exist above and below the
Galactic Center. In order to explain the origin of the gamma-rays,
different theories are proposed. In particular, within hadronic
models, highly-accelerated cosmic rays interact with interstellar
matter and create the observed gamma-rays and in addition...

Solar atmospheric neutrinos are produced in the high energy cascades that follow
cosmic ray interactions with the outer parts of the Sun. We perform an updated
calculation of the solar atmospheric neutrino flux and discuss the impact on searches
for neutrinos from annihilations of weakly interacting massive particles (WIMPs). Our
code is event-based and publicly available, and thus...

In the process of dark matter capture by the Sun, Weakly Interacting Massive Particles
(WIMPs) from the galactic halo can scatter against atomic nuclei in the solar interior,
settle to thermal equilibrium with the solar core and annihilate to produce an
observable flux of neutrinos. When studying this process, the time it takes for a
gravitationally bound WIMP to reach thermal...

Magnetic monopoles are allowed in most extensions of the standard model. They
are allowed in a wide range of masses, of which a large part lies outside of the
reach of modern colliders. Therefore, in order to investigate the high mass range of
magnetic monopoles we must search for monopoles produced in higher energy
environments, such as the early Universe.
According to Dirac’s...

I will review near-term plans for the IceCube Upgrade, longer-term plans for neutrino astronomy in
Antarctica, and the role of Swedish researchers in these efforts.

Detection of cosmological neutrinos with energies in the energy range 10 PeV - 10 Eev
requires efficient detection of signals created in large volumes of matter. A cost
effectid method is readout of fast radiopulses from the Askaryan effect caused by
neutrno interactions in ice. The ARIANNA project proposes to instrument 1300 km^2 of
the Ross Ice shelf with readout stations. I will report...
