1. Measurements of Xmax above 10[sup]17 eV with the fluorescence detector of the Pierre Auger ObservatoryMarko Zavrtanik, Danilo Zavrtanik, Lili Yang, Serguei Vorobiov, Darko Veberič, Marta Trini, Samo Stanič, Ahmed Saleh, Gašper Kukec Mezek, Andrej Filipčič, Alessio Porcelli, 2015, objavljeni znanstveni prispevek na konferenci Opis: For the first time the Pierre Auger Collaboration
presents〈Xmax〉and σ(Xmax) measurements covering nearly three decades of energy. In this analysis we include
new Xmax data obtained with the High Elevation Auger
Telescopes (HEAT) enhancement. The HEAT telescopes cover
a field of view ranging from 30◦ to 60◦ of elevation and are
located next to one of the standard fluorescence detector sites
(Coihueco). The combination of the HEAT and Coihueco telescopes
covers a field of view from ∼2◦ up to ∼60◦ of elevation. Thus,
the combination can sample the longitudinal profile of nearby
lower energy showers, allowing us to extend the energy range
down to 10[sup]17 eV.

2. Measurement of the average electromagnetic longitudinal shower profile at the Pierre Auger ObservatoryMarko Zavrtanik, Danilo Zavrtanik, Lili Yang, Serguei Vorobiov, Darko Veberič, Marta Trini, Samo Stanič, Ahmed Saleh, Gašper Kukec Mezek, Andrej Filipčič, Francisco Diogo, 2015, objavljeni znanstveni prispevek na konferenci Opis: In addition to the standard Xmax and energy, the longitudinal
profiles of extensive air showers contain some more interesting
information. For energies above 10[sup]17.8 eV, we present the
average profiles as a function of atmospheric depth measured
for the first time at the Pierre Auger Observatory. The profile
shapes for different energy ranges are all well reproduced by a
Gaisser-Hillas function within the range studied. A detailed
analysis of the systematic uncertainties is performed using
data and a full detector simulation, and the results are
compared with predictions of hadronic interaction models for different primaries.
