TL;DR
Tunka-Rex Virtual Observatory (TRVO) provides open access to data and software from the Tunka-Rex cosmic ray detector, demonstrating the viability of sparse radio arrays for high-energy cosmic ray measurements.
Contribution
This work publishes Tunka-Rex data and software under open licenses, enabling broader scientific use and following FAIR principles after the detector's decommissioning.
Findings
Cost-effective radio detection of cosmic rays demonstrated
Open data and software facilitate new research projects
TRVO enhances data accessibility and scientific collaboration
Abstract
Tunka-Rex (Tunka Radio Extension) was a detector for ultra-high energy cosmic rays measuring radio emission for air showers in the frequency band of 30-80 MHz, operating in 2010s. It provided an experimental proof that sparse radio arrays can be a cost-effective technique to measure the depth of shower maximum with resolutions competitive to optical detectors. After the decommissioning of Tunka-Rex, as last phase of its lifecycle and following the FAIR (Findability - Accessibility - Interoperability - Reuse) principles, we publish the data and software under free licenses in the frame of the TRVO (Tunka-Rex Virtual Observatory), which is hosted at KIT under the partnership with the KCDC and GRADLCI projects. We present the main features of TRVO, its interface and give an overview of projects, which benefit from its open software and data.
