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...
We present the purpose, long-term development vision, basic design, detection algorithm and preliminary results obtained with Cosmic Ray Extremely Distributed Observatory (CREDO) Detector mobile application. The CREDO app related infrastructure are unique in terms of their scale, targeting many form-factors open-access philosophy. This philosophy translates to open-source code app, both data inflow as well consumption above all, citizen science that means is open all who wish participate...

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,...
Muons and other ionizing radiation produced by cosmic rays radiative decays affect CMOS/CCD sensor. When particles colliding with sensors atoms cause specific kind of noise on images recorded cameras. We present a concept preliminary implementation method for recognizing those events algorithms image processing their classification machine learning.

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...

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...
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 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...
The search for Cosmic-Ray Ensembles (CRE), groups of correlated cosmic rays that might be distributed over very large areas, even the size planet, requires a globally spread and dense network detectors, as proposed by Extremely Distributed Observatory (CREDO) Collaboration. This proposal motivates an effort towards exploring potential using much diversified detection technologies within one system, with units located in hard-to-reach places, where, nevertheless, sensors could work...
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 approach of evolutionary games like prisoner’s dilemma, among others, is based on a consistent strategy. We propose an experimentally verified system where cooperation can arise out two simple factors: mutation and inheritance. This has social dilemma property allows each agent to set its own desired number participants. There are essential mechanisms: fluctuation through which leads cooperation, natural selection tends promote cheaters therefore disrupts the cooperation. It shown in...
Cosmic Ray Ensembles (CRE) are yet not observed groups of cosmic rays with a common primary interaction vertex or the same parent particle. One processes capable initiating identifiable CRE is an ultra-high energy (UHE) photon solar magnetic field which results in electron pair production and subsequent synchrotron radiation. The resultant electromagnetic cascade forms very characteristic line-like front small width ($\sim$ meters), stretching from tens thousands to even many millions...
