The energy spectrum of the UHECRs has been measured up to $10^{20.2}$ eV, and their mass composition has been studied exploiting both the fluorescence and surface detectors of the Observatory. The analysis of the UHECRs arrival directions allowed us to measure their large-scale anisotropies over more than three decades in energy. The searches for intermediate-scale anisotropies are being performed with an exposure now reaching approximately $100,000$ km$^2$sr yr. For the first time, the fluctuations in the number of muons in inclined air showers above $4 times 10^{18}$ eV have been obtained, while more information in the energy range $10^{17.5}-10^{18.3}$ eV comes from the direct measure of muons with the underground scintillators of the Observatory. Moreover, we discuss the limits obtained on the fluxes of neutral particles and the results of the searches for UHE neutrinos from transient astrophysical sources. The new perspectives opened by the current results call for an upgrade of the Observatory, whose main aim is the collection of new information about the primary mass of the highest energy cosmic rays to understand the origin of the observed flux suppression. The progress of the upgrade of the Observatory, AugerPrime, is presented and discussed.","PeriodicalId":166008,"journal":{"name":"Proceedings of 36th International Cosmic Ray Conference — PoS(ICRC2019)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127460490","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}

They also offer the identification capability between muon and electrons and a rough calorimetry for electrons. Using ground-based stations, these properties allow for the development of new tools for the measurement of primary cosmic ray fluxes. In order to verify and quantify the suitability of Trasgo detectors, whether a single one or arrays of them, to provide reliable information of the properties (mass, energy, incoming direction) of primary cosmic rays we have started an initiative for the systematic study of the 'lateral distributions' displayed by electrons and muons, or by bundles of those particles, using MonteCarlo simulations. In a first approach, electrons and muons were produced in vertical showers from primary H, He, C and Fe nuclei, and with incoming energies limited to a maximum of 10$^{15}$ eV per nucleon. This choice represents a significant component of all secondary particles, which can be measured on Earth's surface. The lateral distributions study has been done at the two locations of Santiago de Compostela (Spain) and Livingston Island (Antarctica), where Trasgo detectors are either in operation, or will be operative in the near future.","PeriodicalId":166008,"journal":{"name":"Proceedings of 36th International Cosmic Ray Conference — PoS(ICRC2019)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131443568","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}

These events included the September 10 event also detected as a ground level event. The time intensity profiles in some of these events in both the ACE/SIS instrument and the STEREO/LET instrument both show periods of exponential time decay, making the events amenable to charge states analysis using the method of Sollitt et al.

MAGIC has recently demonstrated its capability as a neutrino detector, by exploiting the Earth-skimming technique. The neutrino-event selection has been studied by pointing the telescopes towards the sea a few degrees below the horizon, with no pre-defined source direction. An upper limit to the $nu_tau$ flux was set. \u0000In this work, a follow-up strategy of given source directions is presented. This new approach is characterised by pointing to targets passing through the sea window observable with MAGIC and for which a trigger from dedicated neutrino observatories is issued with large significance. Above a few tens of PeV, the acceptance of MAGIC to $nu_tau$ is considerably large and compelling results can be obtained for transient events of short duration. The performance of this new method is tested on a sample of data collected by pointing MAGIC for a few days from March to May 2016 towards the direction of a multi-PeV neutrino that IceCube detected on June 11th 2014 (reconstructed direction (J2000.0) RA: 110.34$^circ$ and Dec.: 11.48$^circ$).
