37. Search for Ultra-relativistic Magnetic Monopoles with the Pierre Auger ObservatoryToshihiro Fujii, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, published scientific conference contribution Abstract: Ultra-relativistic magnetic monopoles, possibly a relic of
phase transitions in the early universe, would deposit an
amount of energy comparable to UHECRs in their passage
through the atmosphere, producing highly distinctive air
shower profiles. We have performed a search for
ultra-relativistic magnetic monopoles in the sample of air
showers with profiles measured by the fluorescence detector of
the Pierre Auger Observatory. No candidate was found to satisfy
our selection criteria and we establish upper limits on the
flux of ultra-relativistic magnetic monopoles - the first from
an UHECR detector - improving over previous results by up to an
order of magnitude.

38. Search for energy dependent patterns in the arrival direction of cosmic rays at the Pierre Auger ObservatoryTobias Winchen, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, published scientific conference contribution Abstract: Energy-dependent patterns in the arrival directions of cosmic
rays are expected from deflections in galactic and extragalactic magnetic fields. We report on searches for such
patterns in the data of the surface detector of the Pierre
Auger Observatory at energies above E = 5 EeV in regions
within approximately 15◦ around events with energy E > 60
EeV. No significant patterns are found with this analysis which
can be used to constrain parameters in propagation scenarios.
