The Cosmic Ray Extremely Distributed Observatory (CREDO) is a recently formed, global collaboration dedicated to observing and studying cosmic ray ensembles (CRE): groups of minimum two cosmic rays with common primary interaction vertex or the same mother particle. The CREDO program embraces testing the known CRE scenarios, and getting ready to observe the unexpected physics, it is also...
KM3NeT is a distributed research infrastructure under construction in abyssal sites of the Mediterranean Sea that hosts two underwater neutrino telescopes: ARCA, located offshore Portopalo di Capo Passero in Italy and ORCA, located offshore Toulon in France. Both telescopes employ the same photon detection technology, using spherical optical modules based on the innovative multi-PMT design....
The Southern Wide-field Gamma Ray Observatory (SWGO) is a collaboration to develop and construct an air-shower array for ground-based gamma ray observatory in the Southern Hemisphere. The plan is to improve on or at least equal the performance of similar observatories, like LHAASO or HAWC.
The detector will be installed at an altitude above 4400m a.s.l. It will consist of Water-Cherenkov...
IceCube is a cubic kilometer detector buried in the Antarctic ice at the South Pole. Combined with its surface component, IceTop, it constitutes a unique detector for air-shower physics in the PeV to EeV primary energy regime. In this contribution, a recent measurement of the mean multiplicity of muons with energies above several 100 GeV ("TeV muons") in near-vertical air showers seen in...
Recent analyses of the muon content in extensive air showers produced by cosmic rays above 100 PeV reveal an excess in the data in comparison with Monte Carlo (MC) simulations. These differences point out problems of the high-energy hadronic interaction models, which are not yet understood. In this regard, measurements of different experiments are important, since they could provide some clues...
In high energy Gamma-Ray Astronomy with shower arrays the most discriminating signature of the photon-induced showers against hadron-induced cosmic-ray ones is the content of muons in the observed events.
In the electromagnetic $\gamma$-showers the muon production is due to the dominant channels: photo-production of pions followed by the decay $\pi\to\mu\nu$, prompt leptonic decay of charmed...
Unveiling the still unknown ultra high energy astrophysical sources in the sky greatly benefits of a multimessenger approach, combining information from charged cosmic rays with the one carried by photons and neutrinos. However, implementing this approach necessitates a thorough understanding of the microphysics processes shaping the spectra and energy distribution across these species. In...
Our knowledge about the primary composition of ultra-high-energy cosmic rays (UHECRs) relies heavily on our understanding of extensive air showers and the hadronic interactions governing their development. The Pierre Auger Observatory, the world's largest facility for studying UHECRs, employs various techniques to analyze shower characteristics, which can be exploited to infer the composition...
Neutrinos are a kind of subatomic particle that has become widely studied in several experiments around the world because of its characteristics of only interacting via the so-called weak-interactions and presenting a special behavior called oscillation. It is expected that by analyzing them we could gather insight into some of the Universeโs mightiest enigmas such as confronting elementary...
The hadron production in the simulation of extensive air showers is a long standing problem and the origin of large uncertainties in the reconstruction of the mass of the high energy primary cosmic rays. Hadronic interaction models re-tuned after early LHC data give more consistent results among each other compared to the first generation of models, but still can't reproduce extended air...
The field of air shower physics dedicated to understanding the development of cosmic-ray interactions with the Earth's atmosphere faces a significant challenge regarding the muon content of air showers observed by the Pierre Auger Observatory. Thorough comparisons between extensive air shower (EAS) measurements and simulations are imperative for determining the primary energy and mass of...
CRPropa 3.2, released recently, is the latest update in a continued effort to maintain and extend this open-source code well known in the cosmic-ray community. Originally aimed at simulating the ballistic propagation and interactions of Ultra-High Energy Cosmic Rays (UHECRs), today it can handle diffusive propagation of cosmic rays in a variety of magnetic fields, deal with stochastic cosmic...
The AMS-02 experiment, a multipurpose cosmic ray detector on board the International Space Station since 2011, has reported having detected 7 candidates for antideuterons, 6 antihelium-3, and 3 antihelium-4 during nearly 12 years of operation [1]. Their origin is an open question, on one side their production in cosmic ray interactions (secondary production) is predicted to follow a hierarchy...
Dayalbagh Educational Air Shower Array is the first detector array in Northern India (Uttar Pradesh) to study cosmic rays. Investigations of the physical behaviour of the cosmic ray variations in various time scales are an important aspect of cosmic ray astronomy. In other words, the modulation of cosmic rays is an important tool for investigating disturbed behaviour in the heliosphere....
The Fluorescence Detector (FD) of the Pierre Auger Observatory provides a large exposure for the detection of ultra-high-energy (UHE) upward-going showers (UGS) as suggested by the "anomalous" events reported by ANITA. Recently, strong limits on UGS were obtained using 14 years of FD data, which are in tension with the observations made by ANITA-I and III. Later, ANITA-IV has reported new UGS...
In the course of further processing of data from two similar cosmic ray experiments, carried out in the Tien Shan and Pamir mountains using calorimeters, represented by 2-tier X-ray emulsion chambers (XRECs) with large air gaps (2.12 and 2.5 m, respectively), were obtained distributions of numbers of blackening spots, created by electron-photon cascades (EPCs) on X-ray films, according to the...

Gamma-ray bursts (GRBs) are high-energy events that release isotropic energy on the order of $10^{48}$ - $10^{55}$ erg. They are classified into long or short bursts depending on their observed duration. Long GRBs have a duration ($t_{90}$) greater than 2 seconds, and their progenitors are associated with the collapse of massive stars (collapsars).
Distances are only known for a small...
Correlations between the fluxes of X-rays and TeV gamma-rays in blazars have been reported by observational studies. These correlations are expected in the context of the leptonic Synchrotron Self-Compton (SSC) model. The high-frequency peaked BL Lac object (HBL) blazar Mrk 421 exhibits a linear correlation between these two energy ranges. However, this correlation breaks down at the highest...
Gamma Ray Burst (GRBs) are brief and highly energetic gamma ray explosions, which can be classified into short and long bursts based on their duration. Long GRBs last more than two seconds, and are believed to originate from the collapse of massive stars. Determining the distances to GRBs is challenging due to the current limitations of optical telescopes; only approximately 11% of the...
Detection of charged particles especially cosmic muons is very crucial to study cosmic rays. There are several experiments dedicated to this purpose. Detection of cosmic rays needs detectors covering large areas. The cost of the detectors increases significantly with the increase in the detection area. Gaseous detectors like Resistive Plate Chambers (RPCs) offer a very cost-effective solution...
