The magnetic spectrometer detector AMS-02 has been successfully operating since May 19th, 2011 outside of the International Space Station. More than 230 billion events have been collected by the AMS-02 instrument in 13 years of data taking. The analyses of the high-precision data collected by AMS-02 have been providing novel details and new insights on the composition, spectra, and time...
Since its launch in December 2015, the Dark Matter Particle Explorer (DAMPE) has been operating smoothly for over eight years, showcasing its superior performance in the detection of cosmic rays above the TeV energy region among space-based experiments. Recently, DAMPE has reported new measurement results that further underscore its distinctive contributions to our comprehension of Galactic...
Direct measurements of cosmic rays are unique probes for investigating astroparticle propagation and acceleration in the Galaxy and searching for dark matter signatures. The Calorimetric Electron Telescope (CALET) has been installed on the International Space Station with the main goals of detecting electron, proton, and nuclei spectra. The detector has been continuously operating since 2015...
The HERD (High Energy cosmic-Radiation Detection facility) experiment is a future experiment for the direct detection of high energy cosmic rays that will be installed on the Chinese space station in 2027. Is is constituted by an innovative calorimeter built by about 7500 LYSO scintillating crystals of side 3 cm assembled in a spheroidal shape, such that it has an homogeneous response for...
The High-Altitude Water Cherenkov (HAWC) observatory is a continuously operated, wide field of view detector principally designed to observe astrophysical sources of gamma rays. HAWC can reliably estimate the energy and arrival direction of cosmic and gamma rays arriving from zenith angles of up to 450. As the Earth rotates over one day, HAWC observes a swath of the sky from -260 to 640 in...
The modulation of low-energy cosmic rays reflects interplanetary magnetic field variations and can provide information on solar activity in the past. The secondary particles, which originate from the interaction of cosmic rays with the atmosphere, can be revealed by an array of ground detectors. In this study, we present the investigation of the low-threshold rate (scaler) time series recorded...
Since February 2018, the High-Energy Particle Detector (HEPD-01) has been studying the wide plethora of galactic, solar and trapped particles along the Sun-synchronous and low-Earth orbit of the China Seismo-Electromagnetic Satellite (CSES-01). Entirely designed and built in Italy, this light and compact payload is equipped with a silicon tracking system, a segmented plastic scintillator plane...
The General Antiparticle Spectrometer (GAPS) is a balloon-borne experiment designed to perform low-energy cosmic-ray antinuclei measurements searching for indirect signatures of dark matter annihilation or decay. A wide range of well-motivated dark matter models predicts antinuclei fluxes about two orders of magnitude above the expected astrophysical background below 250 MeV/n. The coverage of...
Recent discoveries of new features in Galactic cosmic-ray fluxes emphasize the importance of understanding the propagation of cosmic rays in our Galaxy. A better understanding of cosmic ray propagation is also important to study the Galactic diffuse emission of high-energy gamma rays and high-energy neutrinos. HELIX (High Energy Light Isotope eXperiment) is a balloon-borne experiment designed...
Cosmic rays are the most energetic particles in the local Universe as they are known to reach energies above few Joules. How and where they are produced have been a science puzzle for several decades now, whose solution has been driving the rising of multi-messenger astrophysics as well as novel theoretical approaches. Of particular interest is the energy range below ~PeV as we expect that...
In recent years, Universities and Research institutions have increasingly developed programs and outreach initiatives aimed at making physics and other scientific disciplines accessible and engaging for a broader audience. The primary goal of these initiatives is to stimulate interest in science, promote understanding of fundamental principles of physics, and inspire future generations of...
The Extreme Energy Events project is an educational and scientific initiative lead by the Museo Storico della Fisica e Centro Studi e Ricerche Enrico Fermi (CREF) and the Istituto Nazionale di Fisica Nucleare (INFN), two research institutes under the control of the Italian Ministero dell’Universita’ e Ricerca ( MUR). The EEE project studies cosmic rays by means of a series of detectors ( 60 )...
For many observatories recording high-energy cosmic rays, gamma rays, or neutrinos, the Earth’s atmosphere is either an integral part or at least a considerable aspect of the detector setup. Several aspects of the influence of the atmosphere and its variability on the development of the observed particle cascades and the signal detected from them will be discussed. Also some atmospheric...
Recent results from high energy space-based missions have revealed unexpected, peculiar structures in cosmic electron, proton and nuclei spectra.
Our knowledge is also improving above the PeV region, due to new observations from ground based detectors that can extend the measurements to very high energies, even if with larger systematics.
In this talk, first, we will dive into the...
