An important s tep towards solving thе problem may be the use of a new technique for reg istering extensive air showers (EAS) in the atmosphere of Earth\, namely m easuring a fluorescent track from orbit. This observation method allows on e to achieve a large exposure and to record events throughout the celestia l sphere with one device.\n\nA program for registering UHECRs from Earth ’s orbit is being implemented in a series of projects. The first of them \, the TUS detector\, was launched aboard the Lomonosov satellite in 2016. During the operation of the detector\, the spatiotemporal structure of th e UV glow of the atmosphere was studied\, and information was obtained on transient flashes that trigger the detector. A number of UV tracks similar to those expected from EAS were recorded in the nocturnal atmosphere.\n\n The next step should be a full-scale telescope with a larger optical syste m and a field of view\, which allows recording dozens of events per year b eyond the GZK cut-off. Such a project\, named KLYPVE-EUSO is being develop ed by the JEM-EUSO collaboration for installation on board the Internation al Space Station. Variants of the lens and mirror telescopes are considere d.\n\nDuring the preparation of the K-EUSO projecta number of pathfinders are being developed: balloon experiments EUSO-Balloon and EUSO-SPB1\, fluo rescence detector at the Telescope Array site. The UV Atmosphere (Mini-EUS O) experiment is operating onboard the Russian Segment of the ISS since Oc tober\, 2019. \n\nA more advanced experiment POEMMA (Probe of Extreme Mult i-Messenger Astrophysics) is planned to be implemented after K-EUSO. It is aimed at detecting both UHECRs and high-energy (above 20 PeV) neutrinos. POEMMA is a system of two telescopes on separate spacecrafts that provide a stereoscopic image of the EAS track and registration of the direct Chere nkov radiation from ascending showers of energetic neutrinos. Currently EU SO-SPB2 project with Cherenkov and fluorescence cameras is in preparation for a launch in Spring 2023 in the path of K-EUSO and POEMMA missions. SIN P MSU develops a digital data processing system for the flourescent telesc ope photodetecting modules.\n\nhttps://indico.nevod.mephi.ru/event/6/contr ibutions/157/ LOCATION:Online Zoom URL:https://indico.nevod.mephi.ru/event/6/contributions/157/ END:VEVENT BEGIN:VEVENT SUMMARY:Generation of cosmic rays of high energy DTSTART;VALUE=DATE-TIME:20210610T135500Z DTEND;VALUE=DATE-TIME:20210610T141000Z DTSTAMP;VALUE=DATE-TIME:20260815T072822Z UID:indico-contribution-20-150@indico.nevod.mephi.ru DESCRIPTION:Speakers: Konstantin Belotsky (National Research Nuclear Unive rsity MEPhI (Moscow Engineering Physics Institute))\nReport will review an d discuss possible mechanisms of generation of high and ultra high energy cosmic rays and gamma radiation.\n\nhttps://indico.nevod.mephi.ru/event/6/ contributions/150/ LOCATION:Online Zoom URL:https://indico.nevod.mephi.ru/event/6/contributions/150/ END:VEVENT BEGIN:VEVENT SUMMARY:Resent results from the Pierre Auger Collaboration DTSTART;VALUE=DATE-TIME:20210609T083500Z DTEND;VALUE=DATE-TIME:20210609T090000Z DTSTAMP;VALUE=DATE-TIME:20260815T072822Z UID:indico-contribution-20-184@indico.nevod.mephi.ru DESCRIPTION:Speakers: Thomas Bretz (University of Aachen)\nWith increased statistics\, the energy spectrum of cosmic rays reveals peculiar features at the highest energies that will be discussed in this contribution.

It was found that both spectra of most abundant primary CR nuclei and the secondary cosmic rays at rigid ity $R > 100−200$ GV exhibit a hardening with increasing rigidity. Thus they deviate from a single power law.\n\nThese newly discovered features a re not easy to explain under standard scenario of cosmic ray origin\, acce leration and propagation in the Galaxy. Under the standard theory\, the pr imary nuclei are thought to be produced\, up to at least several PV\, by s upernova remnant shock waves by diffusive shock acceleration mechanism tha t predicts power-law spectra $J \\propto R^{−\\gamma}$ with slope $\\gam ma ≈ 2.0 − 2.2$. The subsequent CR transport in the turbulent Galactic magnetic fields is modeled as a diffusion process in quasi-homogeneous me dium with the diffusion coefficient $D(R) = D_0 (R/1$ GV$)^\\delta$\, with $\\delta \\approx (0.3 − 0.8)$. Under these assumptions\, the spectrum of primary nucleus $i$ generated by the global-scale steady state distrib ution of sources $S(r\,R)$ is described by a single power law with index $ \\eta = \\gamma + \\delta$\, which is clearly at odds with the observed ha rdening of CR hadrons at GV–TV region.\n\nHowever\, theory and observati ons show that the ISM is inhomogeneous (fractal-like) at the scale of hund reds of parsecs. Stars formation regions also demonstrate fractal features with spatial scales up to about a kpc. Since the particles emitted by Gal actic sources en route to the Solar system pass through regions of the Gal axy that have different properties\, in such a inhomogeneous ISM\, the nor mal diffusion model is certainly not kept valid.\n\nThe non-homogeneous ch aracter of matter distribution and associated spatially intermittent magne tic field leads to the need to incorporate these ISM features into the cos mic ray diffusion model. A possible way to generalize the normal diffusion model is to replace the assumption about statistical homogeneity of inhom ogeneities distribution by their fractal distribution. Non-classical diffu sion is manifested\, in particular\, by abnormally large free paths of pa rticles (so-called “Lévy flights”) and a long stay of particles in in homogeneities\, leading to a presence of the so-called “Lévy traps”.\ n\nIn the current study\, we demonstrate that non-classical diffusion mode l of the cosmic rays in the inhomogeneous Galaxy\, developed by the author s\, allows to describe the main features of nuclei spectra observed in the Solar system. Particularly\, in this model the key feature of the all par ticle energy spectrum — the knee at 3$\\cdot10^{15}$ eV — appears natu rally without additional assumptions. The observed changes in the slope of energy spectra of primary nuclei at rigidity $R > 100−200$ GV caused by the transition from the contribution of multiple distant Galactic sources to the contribution of mainly local ones.\n\nhttps://indico.nevod.mephi.r u/event/6/contributions/149/ LOCATION:Online Zoom URL:https://indico.nevod.mephi.ru/event/6/contributions/149/ END:VEVENT BEGIN:VEVENT SUMMARY:About cosmic ray sources in Galaxy DTSTART;VALUE=DATE-TIME:20210609T075000Z DTEND;VALUE=DATE-TIME:20210609T080500Z DTSTAMP;VALUE=DATE-TIME:20260815T072822Z UID:indico-contribution-20-148@indico.nevod.mephi.ru DESCRIPTION:Speakers: Yuri Stozhkov (LPI RAS)\nIn the last two decades the new expeimental data on cosmic rays about energy spectra in a wide energy range up to 10^13 eV\, isotropy\, ratio of positron flux to electron one\ , and others were obtained.

The mass composition above $10^{14}$ eV is inferred from the extensive air shower (EAS) observations by comparisons with simul ations results\, which rely on accurate description of air shower physics including hadronic interaction models uncertain in the relevant energy ran ge. Numerous methods and techniques are implemented\, including analysis o f mean values\, fluctuations\, correlations or even particular features of distributions of different observables characterized both longitudinal an d spatial shower development (depth of maximum\, muon production depth\, t otal number of electrons and muons at the observation level and their loca l densities at various distances from the shower axis\, particles arrival time profiles\, spatial distributions of radio emission and Cherenkov ligh t etc.). Large efforts have been made recently in both gaining experimenta l data with increased resolution in detection of various EAS components an d developing improved methods for physical interpretation of the data alon g with evolving hadronic interaction models after the LHC results. Neverth eless\, the composition results still remain ambiguous in the entire energ y range available for EAS studies.\n\nThe discrepancies between estimates of mass composition derived by various methods from the data of different experiments\, in addition to insufficiency in statistics\, are apparently caused by complex of instrumental and methodological systematic biases of different nature\, as well as by strong model dependence of the observable s\, mostly in case of muon component characteristics (so-called “Muon Pu zzle”)\, disadvantages in taking into account meteorological effects etc .\n\nA possible solution might be achieved with refined (multi-)hybrid mea surements together with generalizations of the analysis by revealing unive rsal features\, based on the intrinsic physic properties of air showers\, evaluation of new parameters and functionals\, which are weakly sensitive to the hadronic interaction model being good primary mass indicators.\n\nI n this paper we present the updated analysis of spatial distributions of e lectrons and muons with respect to the scale invariance in lateral distrib ution (LD) functions (the extended scaling formalism). We demonstrate that this formalism enables accurate description of lateral distributions of e lectrons and muons by one-parametric scale-invariant functions in wide pri mary energy and radial distance ranges. The scale-invariance of LD and air shower universality manifesting through the functional dependence between radial scale factors and longitudinal shower age are both insensitive to hadronic interaction models. An additional composition sensitive observabl e\, which can be included in the multicomponent analysis of experimental d ata obtained by 100% duty cycle ground-based detectors\, is time profile o f charged particles measured by surface scintillation counters at differen t ranges of radial distances.\n\nThus\, integrated spatial and temporal ch aracteristics of the charged EAS component can be effectively used as a so urce of the improved cosmic ray mass composition results when interpreting the experimental data of the ground-based EAS arrays. The proposed approa ch could be implemented for the present and future (multi-)hybrid air show er observations by TAIGA\, Yakutsk Complex Air Shower Array\, Auger and Te lescope Array observatories taking into account their upcoming upgrades\, as well as for re-analysis and cross-calibration of the data collected fro m different air shower arrays within the single method in a broad primary energy range.\n\nhttps://indico.nevod.mephi.ru/event/6/contributions/147/ LOCATION:Online Zoom URL:https://indico.nevod.mephi.ru/event/6/contributions/147/ END:VEVENT BEGIN:VEVENT SUMMARY:Cosmic ray study at the Astrophysical Complex TAIGA: results and p lans DTSTART;VALUE=DATE-TIME:20210609T070000Z DTEND;VALUE=DATE-TIME:20210609T072500Z DTSTAMP;VALUE=DATE-TIME:20260815T072822Z UID:indico-contribution-20-146@indico.nevod.mephi.ru DESCRIPTION:Speakers: Leonid Kuzmichev (SINP MSU)\nTAIGA (Tunka Advanced I nstrument for cosmic ray physics and Gamma Astronomy) Astrophysical comple x is being developed for studies of gamma rays and charged cosmic rays in the energy range of 10^13 - 10^18 eV.
