NuRadioMC is a framework for the simulation of ultra-high-energy neutrino detectors that measure the radio signal emitted in neutrino-induced particle cascades. It is used in different radio neutrino experiments, such as RNO-G and is partly adopted by the cosmic-ray detectors LOFAR and SKA. The software enables end-to-end simulation of all relevant components starting with the neutrino...

In-ice radio detection is a rapidly developing field in which detector design choices made now can have a lasting impact on the sensitivity of EeV neutrino searches. While brute-force simulation campaigns are infeasible for large design parameter spaces, differentiable programming makes it possible to compute gradients of a scientific objective with respect to detector design parameters,...

Ultra-high-energy (UHE) neutrinos are unique cosmic messengers that can traverse cosmological distances unattenuated, providing direct insight into the most energetic processes in the universe. Radio detection offers significant advantages for detecting highly inclined air showers induced by UHE neutrinos, due to a larger exposure range compared to particle detectors, resulting from minimal...

Several balloon-borne radio experiments have targeted the detection of ultra-high energy neutrinos interacting near the Earth's surface. Radio pulses produced by cosmic ray air showers constitute a relevant class of events among the recorded signals. Cosmic ray signals can be produced either by downward-going air showers, where the signal reflects off the Earth's surface before reaching the...

The Radar Echo Telescope (RET) aims to observe the cosmic neutrino flux at the highest energies (>10 PeV) using radar. Radar allows for determining the position, speed and direction of any radio-reflecting object. In-ice neutrino interactions leave a dense ionisation trail that can serve as a short-lived macroscopic radar target. Therefore, radar is a potential cost-effective radio-based...

The Radar Echo Telescope for Cosmic Rays (RET-CR) is a pathfinder experiment for a future neutrino telescope, using cosmic rays as an in-situ test beam. The buried radar system monitors for echoes off high-energy cosmic-ray induced in-ice cascades. The RET signal and dataset is well suited to a sub-threshold analysis, with properties that can be exploited in a singular-value-decomposition...

Experiments that use self-triggered radio detection need accurate knowledge of their local radio background. This project aims to develop a general measurement setup to examine this background and provide information for site evaluation. The setup has to be sensitive over a wide range of frequencies, it has to be accurate and it needs to be built in a way to minimize its own radio...
