42. Ideas to measure the prompt component of the atmospheric muon flux

06/12/2022 16:05

Poster 1

Extensive air showers arise due to particles coming from the Universe interacting with the atmosphere. In these high-energetic interactions, many particles of different types
are produced.
Since muons have a long lifetime and thus a long range compared to other particles in the air shower, they are abundant even on the Earth's surface. These muons are detected with air shower detectors and...

38. Observation of Cosmic-Ray Anisotropy with Eleven Years of IceCube Data

06/12/2022 16:20

Poster 1

The complete IceCube Observatory has collected over 690 billion cosmic-ray induced muon events from May 2011 to May 2022. These unprecedented statistics make it possible to observe significant structure in in the distribution of cosmic-ray arrival directions at both higher cosmic-ray energies and smaller angular scales. Combined with improved simulation and systematics, we can provide a newly...

41. Anisotropies studies in the arrival directions of Ultrahigh-Energy Cosmic Rays

06/12/2022 16:32

Poster 1

The study of ultrahigh-energy cosmic rays contributes to a better understanding of the Universe. In particular, the study of anisotropy in their arrival directions is of key importance to unraveling the sources of such particles. The Pierre Auger Observatory, the largest cosmic ray observatory in the world, collected an unprecedentedly large
data set over 17 years of operation. In this...

44. Magnetic diffusion and interaction effects on Ultrahigh Energy Cosmic Rays

06/12/2022 16:44

Poster 1

Magnetic fields present in the Universe and interactions with the cosmic radiation backgrounds play an important role in shaping the flux of the ultrahigh energy cosmic rays reaching the Earth. To account for these processes we include in the SimProp cosmic ray propagation code the effect of a turbulent magnetic field through a stochastic deflection term in the trajectories. We compute the...

39. Search for photons at the Pierre Auger Observatory

06/12/2022 16:56

Poster 1

The Pierre Auger Observatory is the largest and most accurate air-shower experiment in the world. An essential characteristic of the Pierre Auger Observatory is the hybrid concept, combining a Surface Detector array (SD) with a Fluorescence Detector (FD), offering a large exposure and unique discrimination capabilities to photons with energy above $10^{17}$ eV. The analysis of data taken over...

40. The Underground Muon Detector of the Pierre Auger Observatory

06/12/2022 17:08

Poster 1

Ultrahigh-energy cosmic rays are a mystery at the frontier of high-energy particle physics and astronomy. The Pierre Auger Observatory is currently the largest detector for ultrahigh-energy cosmic rays in the world and will continue to search for the origins of cosmic rays at the highest energies in its second phase of operation. We will present the potential and the functionality of the...

43. High-energy lepton and photon simulations with the framework PROPOSAL

06/12/2022 17:20

Poster 1

Modern analysis methods in cosmic ray physics rely on precise and efficient simulations of high-energy particles.
To simulate the propagation of charged leptons and photons, the tool PROPOSAL has been developed.
It provides a 3D Monte Carlo simulation optimized for high-energy particles, usable in C++ and Python.

We present the simulation framework PROPOSAL and a selection of its...
