It measures the MHz radio emission of extensive air showers produced by cosmic rays hitting our atmosphere. We show the recent work by AERA, such as the measurement of the muon content of inclined air showers and the stability of the measured radio signal over almost a decade, as measured with the Galactic radio background. In particular, we highlight the measurements of the depths of the shower maxima 𝑋 max , which we use to make inferences about the mass composition of cosmic rays. We reconstruct 𝑋 max by comparing the measured radio footprint on the ground to an ensemble of footprints from Monte-Carlo CORSIKA/CoREAS air shower simulations. We compare our 𝑋 max reconstruction with fluorescence 𝑋 max measurements on a per-event basis, a setup unique to the Pierre Auger Observatory, and show the methods to be fully compatible. We determine the resolution of our method as a function of energy and reach a precision better than 15 g cm − 2 at the highest energies. With a bias-free set of around 600 showers, we find agreement with the Auger fluorescence measurements at energies between 10 17 . 5 to 10 18 . 8 eV.","PeriodicalId":375543,"journal":{"name":"Proceedings of 27th European Cosmic Ray Symposium — PoS(ECRS)","volume":"336 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121249987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Choutko, Qi Yan","doi":"10.22323/1.423.0012","DOIUrl":"https://doi.org/10.22323/1.423.0012","url":null,"abstract":"We report the properties of cosmic ray nuclei from protons to nickel (Z=1–14, 16, 26, and 28) in the rigidity range from 2 GV to 3 TV collected by the Alpha Magnetic Spectrometer on the International Space Station from May 19, 2011 to May 6, 2021. We found that the primary cosmic rays He-C-O-Fe-Ni, and Ne-Mg-Si-S belong to two different classes of cosmic rays. We also found that the secondary cosmic rays Li-Be-B and F belong to another two different classes of cosmic rays.The rigidity dependences of the secondary cosmic rays and the primary cosmic rays are distinctly different. In particular, above ∼ 200 GV the secondary cosmic rays harden twice as much as the primary cosmic rays. The third group of cosmic rays N, Na, and Al can be described as linear combinations of primary (O, Si) and secondary (B, F) cosmic rays. Compared with O and Si, the primary cosmic rays C, Ne, Mg, and S were found to have secondary component, similar to N, Na, and Al. As a result, the C/O, N/O, Ne/Si, Na/Si, Al/Si, Mg/Si, and S/Si abundance ratios at the source are directly determined independent of cosmic ray propagation. Finally, we found that the lightest and most abundant primary proton cosmic rays have two components, the first being with the same rigidity dependence as He-C-O-Fe-Ni and the second with rigidity spectral index softer than the first one by Δ 𝑝 / 𝐻𝑒 = 0 . 30 ± 0 . 01.","PeriodicalId":375543,"journal":{"name":"Proceedings of 27th European Cosmic Ray Symposium — PoS(ECRS)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116426610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We construct a global model of NGC891 based on the observational characteristics of this galaxy. We assume that on large scales, the dynamics of the magnetized ISM is driven by Cosmic Rays. We apply the coarse-grained momentum finite volume (CGMV), for solving the Fokker–Planck CR transport equation for CR electrons in ”Cosmic Ray Energy SPectrum” (CRESP) module of PIERNIK MHD code to model CR propagation in this galaxy. The overall propagation of cosmic rays is described by the Fokker-Planck equation. The numerical model exhibits magnetic field amplification by CR-driven dynamo. We perform a parameter study of the system by varying the injection spectrum slope, the magnitude and momentum dependence of the CR electron diffusion coefficients and SFR. We take into account the advection, diffusion, and adiabatic changes as well as synchrotron and inverse-Compton losses. The spectrum of synchrotron radiation, polarization maps and spectral index maps reproduce the observed structures of the real edge-on galaxy very well. Comparison of different models suggests harder CR 𝑒 − injection spectra, higher conversion ratios of SN → CR energies (of 10–20%) and diffusion coefficients ∼ 9 × 10 28 cm 2 s − 1 .","PeriodicalId":375543,"journal":{"name":"Proceedings of 27th European Cosmic Ray Symposium — PoS(ECRS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132411013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
