Description

Participants of the CREDO Project funded by the International Visegrad Fund meet at the Silesian University in Opava, Czech Republic on November 21-23, 2019.

The Cosmic-Ray Extremely Distributed Observatory (CREDO) project will use the hunt for particle cascades from deep space as a vehicle for a unique ‘bottom-up’ approach to scientific research. By engaging the non-specialist public of all ages as ‘citizen scientists’ CREDO will create and widely offer an opportunity for lifelong learning for individuals as well as for cooperation and the sharing of common educational tools amongst institutions. The discoveries of these citizen scientists will feed directly into a pioneering new area of scientific research oriented on Cosmic Ray Ensembles (CRE). The detection (or non-detection) of such particle groups promises to open up a new method for exploring our universe. The opportunities this would create for cross-disciplinary research are significant and beneficial for individuals, networks of institutions and the global communities of both professional scientists and science enthusiasts.

The workshop will be focused on the scientific (both theoretical and experimental), organizational and fundraising aspects of the CREDO project. Special attention will be devoted to such objectives, as the integration of the CREDO data resources with existing open data networks, further improvement of public engagement through the collaboration with high schools, elementary schools and teachers and fundraising topics mainly related to forthcoming Horizon 2020 Science with and for Society (SwafS) calls. Furthermore, the workshop will serve as a platform for a Collaboration Meeting where the current issues of the CREDO collaboration can be raised in the form of presentations, round tables and individual discussions. 

The CREDO workshop is open to press and media representatives.

It is possible to use Vidyo to attend the meeting remotely. Videoconference will be available after opening the link:

The workshop is supported financially by the Governments of Czechia, Hungary, Poland and Slovakia through Visegrad Grant from International Visegrad Fund. The mission of the Fund is to advance ideas for sustainable regional cooperation in Central Europe.

      Heterogeneous computing platform HybriLIT is a part of the Multifunctional information and computing complex (MICC) of the Laboratory of Information Technologies of JINR. The platform consists of “Govorun” supercomputer and HybriLIT cluster as an education, scientific and testing polygon. It is based on heterogeneous structure of computation nodes and allows developing parallel applications for carrying out data analysis and computation using various computing architectures such as multicore CPUs, Intel Xeon Phi co-processors, and NVIDIA (Tesla K40, K80, V100) GPUs. Therefore, the platform provides the unified software and information environment and ecosystems for parallel computations and for ML/DL. It also provides a possibility to hold tutorials in parallel programming technologies that help students and scientists to learn new computing architectures.

      Robert Kamiński / CREDO project (online talk) 30m

      The Cosmic-Ray Extremely Distributed Observatory (CREDO) is a project created a few years ago in the Institute of Nuclear Physics PAS in Krakow and dedicated is to global studies of extremely extended cosmic-ray phenomena. The main reason for creating such a project was that the cosmic-ray ensembles are beyond the capabilities of existing detectors and observatories. Until now, cosmic ray studies, even in major observatories, have been limited to the recording and analysis of individual air showers therefore ensembles of cosmic-rays, which may spread over a significant fraction of the Earth were neither recorded nor analyzed.

    • 10:00 AM 10:30 AM
      David Alvarez Castillo / Ultra High Energy Cosmic Rays produced by compact star mergers and pulsars 30m

      In this talk I shall review a few mechanisms of ultra high energy cosmic rays produced by the merger of compact objects, supernovae infall into magnetars, formation of hybrid compact stars and emissions from pulsars. Moreover, I will discuss the physical implications of these processes within the framework of CREDO detections.

      Arman Tursunov / Acceleration of ultra-high-energy cosmic rays by supermassive black holes 30m

      Production and acceleration mechanisms of ultra-high-energy cosmic rays (UHECRs) with energy exceeding EeV remain unclear. Energy range of UHECRs beyond the GZK-cutoff limit points to exotic nature of the phenomena. I will show that extraction of rotational energy of a black hole by the novel, ultra-efficient regime of the magnetic Penrose process could indeed foot the bill. Ionization of particles, such as beta-decay of neutron, skirting close to the black hole horizon energizes protons to over 10^20 eV. It is remarkable that the process requires neither extended acceleration zone, nor fine-tuning of accreting matter parameters. Further, this leads to a certain verifiable constraints on the black hole mass and magnetic field strength as UHECRs sources. Applied to the Galactic center supermassive black hole we have proton energy of orders coinciding with the knee of the cosmic ray spectra. I will also discuss the results of numerical studies related to the acceleration of primary cosmic rays and energy losses along the propagation distance.

      Kevin Almeida Cheminant / Search for ultra-high energy photons through the preshower effect with CTA telescopes 20m

      As ultra-high energy photons (EeV and beyond) propagate from their sources of production to Earth, radiation-matter interactions can occur, leading to an effective screening of the incident flux. In the ultra-high energy domain, photons can undergo e+ /e− pair production when interacting with surrounding geomagnetic field, which in turn can produce cascade of electromagnetic particles called preshower. Such cascade can initiate air showers in the Earth’s atmosphere that gamma-ray telescopes, such as the next-generation gamma-ray observatory Cherenkov Telescope Array, can detect through Cherenkov emission. We study the feasibility of detecting such phenomena using Monte-Carlo simulations of nearly horizontal air showers for the example of the La Palma site of the Cherenkov Telescope Array. We investigate the efficiency of multivariate analysis in correctly identifying preshower events and cosmic ray dominated background. The effective area for such kind of events are also investigated and event rate predictions related to different ultra-high energy photons production models are presented.

      Tadeusz Wibig / The First CREDO Registration of Extensive Air Shower 30m

      We have described the CREDO-Maze mini array with four CosmicWatch detectors. We show that this simple and affordable apparatus is able to register the Extensive Air Showers and it can be used to study cosmic rays much more effectively that the simple two-detector CosmicWatch muon telescope station. The further development direction is indicated.

    • 2:50 PM 3:10 PM
      Paweł Jagoda / Numerical simulations of Extensive Photon Cascades and study of their signatures in the Cosmic-Ray 20m

      The cosmic ray research has been so far focused on investigating single air showers. In contrast, the CREDO project is dedicated to studying extremely distributed cosmic ray phenomena, so-called Super-PreShowers. If photons constitute a fraction of ultra-high energy primary particles, on their way through space they may initiate cascades comprising thousands of secondary elements. The simulation package developed attempts to model possible signatures of those events which we expect to observe in the extremely distributed observatory. The model of cascade development employed is governed by a simple probabilistic scenario, which gives similar results in terms of the number of particles and spatial dispersion as anticipated in real experiment. The presented visualisation tool provides signature maps of events that occur in remote locations. The signature maps are designed to be comprehensible to citizen scientists. The resulting map images are made available through the Dark Universe Welcome project. Undoubtedly, both detection as well as non-detection of such an event will extend our knowledge of Universe.
