94. The Depth of the Shower Maximum of Air Showers Measured with AERA

Dr Pont, Bjarni (Radboud University)

6/9/22, 9:00 AM

The Auger Engineering Radio Array (AERA) is an array of $153$ radio antennas spanning an area of $17$ km$^2$, currently the largest of its kind, that probes the nature of ultra-high energy cosmic rays at energies around the transition from Galactic to extra-galactic origin. It measures the MHz radio emission of extensive air showers produced by cosmic rays hitting our atmosphere. The elemental...

110. Mass composition of cosmic rays from Xmax reconstruction with LOFAR

Corstanje, Arthur (Vrije Universiteit Brussel (VUB))

6/9/22, 9:20 AM

We present the results of a new cosmic ray composition analysis above $10^{16.8}$ eV, based on measurements of the depth of air shower maximum $X_{\rm max}$ using the LOFAR radio telescope.
The reconstruction is done by simulating the radio signal for an ensemble of showers using Corsika and CoREAS.
The radio footprints on the ground are fitted to the measured radio data, yielding an...

118. Constraining the cosmic-ray mass composition by measuring the shower length with SKA

Buitink, Stijn (Vrije Universiteit Brussel (VUB))

6/9/22, 9:40 AM

The current generation of air shower radio arrays has demonstrated that the atmospheric depth of the shower maximum Xmax can be reconstructed with high accuracy. These experiments are now contributing to mass composition studies in the energy range where a transition from galactic to extragalactic cosmic-ray sources is expected. However, we are still far away from an unambiguous interpretation...

80. Potential of the Askaryan Fraction of the Radio Emission from Cosmic-Ray Air Shower for Xmax Reconstruction

Paudel, Ek Narayan

6/9/22, 10:00 AM

There is an ongoing effort to improve the sensitivity of the IceTop surface array at the South Pole by the addition of surface radio antennas. With a simulation study, we investigated the dependencies of the Akaryan relative to the geomagnetic emission in the band of 70-350 MHz at the South Pole. We used CoREAS to simulate the radio emission from cosmic-ray air showers at that location using a...

90. Energy and Xmax Reconstruction for Cosmic-Ray Events Recorded by a Prototype Station of the IceCube Surface Enhancement

Turcotte-Tardif, Roxanne

6/9/22, 10:20 AM

The IceTop array, located at the surface of the IceCube Neutrino Observatory, is currently used as a veto for the in-ice neutrino detection as well as a cosmic-ray detector. Over the years, snow accumulated on the IceTop detector reducing its sensitivity and resolution. In order to mitigate this issue as well as further increase the accuracy of cosmic-ray measurements, an enhancement is...

86. Measuring the muon content of inclined air showers using AERA and the particle detector of the Pierre Auger Observatory

Mr Gottowik, Marvin (Bergische Universität Wuppertal)

6/9/22, 10:40 AM

A first measurement of the muon content of an air shower using hybrid radio and particle detection is presented. For inclined air showers with zenith angles above 60°, the water-Cherenkov detector (WCD) of the Pierre Auger Observatory performs an almost pure measurement of the muonic component, whereas the Auger Engineering Radio Array (AERA) allows reconstructing the electromagnetic energy...

125. A new method to determine Xmax based on the reconstruction of longitudinal profile of air showers using radio signals

Ms Jhansi, V.B. (Khalifa university)

Precise measurement of the composition of cosmic rays in the energy range of $10^{16}$ to $10^{18}$ eV may settle the long standing issue of the galactic or extra galactic origin of these particles in the energy region. Ground-based experiments mostly rely on the determination of the depth of air shower maximum ($\rm X_{max}$) to measure the type of cosmic-ray particle. One efficient...
