Russian–German Astroparticle Data Life Cycle Initiative

Abstract

Modern large-scale astroparticle setups measure high-energy particles, gamma rays, neutrinos, radio waves, and the recently discovered gravitational waves. Ongoing and future experiments are located worldwide. The data acquired have different formats, storage concepts, and publication policies. Such differences are a crucial point in the era of Big Data and of multi-messenger analysis in astroparticle physics. We propose an open science web platform called ASTROPARTICLE.ONLINE which enables us to publish, store, search, select, and analyze astroparticle data. In the first stage of the project, the following components of a full data life cycle concept are under development: describing, storing, and reusing astroparticle data; software to perform multi-messenger analysis using deep learning; and outreach for students, post-graduate students, and others who are interested in astroparticle physics. Here we describe the concepts of the web platform and the first obtained results, including the meta data structure for astroparticle data, data analysis by using convolution neural networks, description of the binary data, and the outreach platform for those interested in astroparticle physics. The KASCADE-Grande and TAIGA cosmic-ray experiments were chosen as pilot examples.

Seven years of Tunka-Rex operation

“…Following the approach chosen in the German-Russian Astroparticle Data Life Cycle initiative (GRADLCI) [30] based on the ideas of KDCD [31] we are preparing to publish the data of Tunka-Rex under a free data license in the frame of the Tunka-Rex Virtual Observatory (TRVO). We plan to publish all possible data layers (DL) starting from the lower ones (DL0-2), namely raw radio traces, voltages in channels and reconstructed electrical fields, and finishing with high-level cosmic ray reconstruction and different radio maps (DL3+).…”

Special Issue on Astrophysics & Geophysics: Research and Applications

“…Current trends in the era of Big Data highlight the importance of open science and new ideas not only in astro and geophysics but also in other areas of research. In their study, Bychkov et al [6] propose the creation of an open science system which enables researchers to publish, store, search, select, and analyze astroparticle physics data. A web platform such as this and the obtained results would be of great importance in modern science.…”

“…This Special Issue, "Astrophysics & Geophysics: Research and Applications" [5], contains five articles, which include a wide range of topics such as big data in astrophysics and geophysics, data mining and machine learning in the petabyte era, data processing, visualization of high-dimensional data, remote sensing, etc. While some papers are focused on a particular investigation [6][7][8], there are others which [9,10] aim to provide scientists with the required supporting information helping them completely understand and use the data described with a high level of confidence.…”

A Distributed Storage for Astroparticle Physics

“…The prototype of such distributed storage is developed in the framework of the German-Russian Astroparticle Data Life Cycle Initiative [10]. This initiative aim is develop of a distributed data storage system in the field of astrophysics of particles using the example of two experiments -KASCADE and TAIGA and demonstrate it works.…”
