Status of neutrino astronomy
Julia K. Becker
Astrophysical neutrinos can be produced in proton interactions of charged cosmic rays with ambient photon or baryonic fields. Cosmic rays are observed in balloon, satellite and air…
No observational constraints from hypothetical collisions of hypothetical dark halo primordial black holes with galactic objects
Marek A. Abramowicz, Julia K. Becker, Peter L. Biermann +3
It was suggested by several authors that hypothetical primordial black holes (PBHs) may contribute to the dark matter in our Galaxy. There are strong constraints based on the Hawki…
Neutrinos from active black holes, sources of ultra high energy cosmic rays
Julia K. Becker, Peter L. Biermann
A correlation between the highest energy Cosmic Rays (above ~ EeV) and the distribution of active galactic nuclei (AGN) gives rise to a prediction of neutrino production in the sam…
High-energy neutrinos in the context of multimessenger physics
Julia K. Becker
The field of astroparticle physics is currently developing rapidly, since new experiments challenge our understanding of the investigated processes. Three messengers can be used to…
Tau neutrino search with the MAGIC telescope
M. Gaug, C. Hsu, J. K. Becker +4
The MAGIC telescope located on the Roque de los Muchachos on the Canary Island La Palma at a height of 2200 m a.s.l. is able to point to the sea. This permits a search for air show…
On the origin of ultra high energy cosmic rays: Subluminal and superluminal relativistic shocks
Athina Meli, Julia K. Becker, John J. Quenby
The flux of Ultra High Energy Cosmic Rays (UHECRs) at eV is believed to arise in plasma shock environments in extragalactic sources. In this paper, we present a syste…
