CREDO Visegrad Workshop 2019

Workshop Opening & Motivation Highlights

State of art, our plans and conception of usage the machine learning and reinforcement learning for classification of cosmic-ray events from CREDO database.

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...

Collaboration Meeting: only for CREDO contributors.

Visegrad Project Meeting: for V4 project members and CREDO contributors.

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...

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.

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...

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...

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.

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...

Audiovisual, interactive art performance powered by CREDO - one of the main drivers for the CREDO mission.

I would like to present information about the "particle hunters" competition in Poland, and show the status of work on the user interface being developed by me.
