The Cosmic Ray Extremely Distributed Observatory (CREDO) is a newly formed, global collaboration dedicated to observing and studying cosmic rays (CR) ray ensembles (CRE): groups of minimum two CR with common primary interaction vertex or the same parent particle. CREDO program embraces testing known CRE scenarios, preparing observe unexpected physics, it also suitable for multi-messenger multi-mission applications. Perfectly matched capabilities, could be formed both within classical models...
Abstract Propagation of ultra-high energy photons in the solar magnetosphere gives rise to cascades comprising thousands photons. We study cascade development using Monte Carlo simulations and find that are spatially extended over millions kilometers on plane distant from Sun by 1 AU. estimate chance detection considering upper limits current cosmic rays observatories order provide an optimistic rate 0.002 events per year a chosen ring-shaped region around Sun. compare results which use two...
Gamification is known to enhance users’ participation in education and research projects that follow the citizen science paradigm. The Cosmic Ray Extremely Distributed Observatory (CREDO) experiment designed for large-scale study of various radiation forms continuously reach Earth from space, collectively as cosmic rays. CREDO Detector app relies on a network involved users now working worldwide across phones other CMOS sensor-equipped devices. To broaden user base activate current users,...
The Cosmic-Ray Extremely Distributed Observatory (CREDO) is a project dedicated to global studies of extremely extended cosmic-ray phenomena, the ensembles (CRE), beyond capabilities existing detectors and observatories. Up date, research has been focused on detecting single air showers, while search for cosmic-rays, which may overspread significant fraction Earth, scientific terra incognita. Instead developing commissioning completely new detector infrastructure, CREDO proposes approaching...
The Cosmic Ray Extremely Distributed Observatory (CREDO) pursues a global research strategy dedicated to the search for correlated cosmic rays, so-called Ensembles (CRE). Its general approach CRE detection does not involve any priori considerations, and its encompasses both spatial temporal correlations, on different scales. Here we time clustering of ray events collected with small sea-level extensive air shower array at University Adelaide. consists seven one-square-metre scintillators...
Active galactic nuclei (AGNs) are considered to be one of the most appropriate sources ultra high energy cosmic rays (UHECRs, $E \gtrsim 10^{18} \mathrm{~eV}$). Radiogalaxy Virgo A (M87) in centre a cluster galaxies Cluster (VC) can prominent source UHECRs. We investigate possible contribution and VC flux events with trans-GZK energies - extremely (EHECRs) from recent Auger Telescope Array (TA) data sets ($E > 52 \mathrm{~EeV}$ 57 \mathrm{~EeV}$, respectively). simulate EHECR propagation...

The Cosmic-Ray Extremely Distributed Observatory (CREDO) uses the hunt for particle cascades from deep space as a vehicle unique ``bottom-up'' approach to scientific research. By engaging non-specialist public of all ages ``citizen scientists'' we create opportunities lifelong learning individuals well cooperation and sharing common educational tools amongst institutions. discoveries these citizen scientists will feed directly into pioneering new area research oriented on Cosmic Ray...

Both the lack of observation ultra-high energy (UHE) photons and limitations state-of-the-art methodology being applied for their identification motivate studies on alternative approaches to relevant simulations related observational strategies. One such new is proposed in this report it concerns observables allowing indirect UHE through cosmic ray phenomena composed many spatially correlated extensive air showers or primary rays observed at one time. The study based interactions with...

Up date research has been focused on detecting single air showers, while search for cosmic-rays, which may spread over significant fraction Earth, scientific terra incognita. key idea CREDO combine (large professional arrays, educational instruments, individual detectors,...
The Cosmic-Ray Extremely Distributed Observatory (CREDO) is an infrastructure for global analysis of extremely extended cosmic-ray phenomena, so-called super-preshowers, beyond the capabilities existing, discrete, detectors and observatories. To date research has been focused on detecting single air showers, while search ensembles events induced by super-preshowers a scientific terra incognita - CREDO explores this uncharted realm. Positive detection would have impact ultra-high energy...
Although the photon structure is most efficiently studied with accelerator instruments, there also a scientifically complementary potential in investigations on photons produced outer space. This already being explored gamma ray telescopes, ultra-high energy cosmic observatories and, since very recently, by Cosmic-Ray Extremely Distributed Observatory (CREDO). Unlike former instruments focused detection of single photons, CREDO aims at cascades (ensembles) originating even astrophysical...
For the data on observation times and directions of motion extensive air showers, which are observed at two stations GELATICA network, for first time we apply method have developed previously identifying pairs mutually remote ancestor particles arose, possibly, in a single process. A brief description review properties used samples shower observations network during 2019–2021 session, result applying above to them given. Some peculiar pair showers discussed. side question arose about cause...
We have noticed in many places around the world recent years an increasing interest small-scale extensive air shower experiments designed to satisfy young people's scientific curiosity and develop their science physics particular. It is difficult think of ways opportunities introduce practical classes modern high-energy physics, astrophysics, or particle into school curricula after-school activities. Small EAS array are just such a proposal. As part CREDO-Maze project, we plan equip local...
Cosmic Ray Ensembles (CRE) are very large, yet not observed particle cascades initiated above the Earth atmosphere. Such could be formed both within classical models (e.g. products of photon-photon interactions) and exotic scenarios result decay Super Heavy Dark Matter particles subsequent interactions). Some CRE might have a significant spatial extent which serve as unique signature detectable with existing cosmic ray infrastructure taken network detectors. This would composed number air...
The main objective of the Cosmic-Ray Extremely Distributed Observatory (CREDO) is detection and analysis extended cosmic ray phenomena, so-called super-preshowers (SPS), using existing as well new infrastructure (cosmic-ray observatories, educational detectors, single detectors etc.). search for ensembles events initiated by SPS yet an untouched ground, in contrast to current state-of-the-art analysis, which focused on events. Theoretical explanation could be given either within classical...
Cosmic rays interact with fields and background radiation as they propagate in space, producing particle cascades of various sizes, shapes constituents.
