Evaluation of the Uncertainties of the Galactic Magnetic Field to Elucidate the Origin of Ultra-High Energy Cosmic Rays

Objective

"We propose to develop a new analysis approach for charged particle
astronomy to find the astrophysical sources of cosmic particles with
extreme energies.

During the recent years, there has been a rapid progress in our
understanding of Galactic magnetic field (GMF) and the collected
statistics of ultra-high energy cosmic ray events. It should therefore
be possible to correct the measured arrival directions of cosmic rays
on Earth for deflections in the GMF and to significantly improve the
search for their astrophysical sources in this way. The research
objectives of this proposal are therefore: 1) A thorough evaluation of
the uncertainties of the GMF with the aim of producing sky maps of the
deflection uncertainty of cosmic rays given their arrival direction
and rigidity (= energy divided by charge). 2) Development of an optimal
analysis method for correlation studies that takes into account the
deflection uncertainties originating from the uncertainties in both,
GMF and the estimated rigidities. 3) Application of the optimal data
analysis method to data of the Pierre Auger Observatory.


During the outgoing phase, the fellow will join the astrophysics group
of the New York University to acquire state-of-the art knowledge on
the interpretation of astrophysical data relevant for the GMF.
At the return host, the Karlsruher Institute of
Technology, he will apply the obtained knowledge to data of the
Pierre Auger Observatory.

This project will allow the fellow to be trained in the theoretical
foundations and computational tools needed to study the GMF.
It will broaden his knowledge in astrophysics and
therefore complement his current expertise of the particle physics of
air showers. The interdisciplinary training and the possibility to
gain teaching experience at both hosts, will contribute to the
long-term development of the fellow’s career and make him eligible
for a leading academic position in Europe."
