High energy cosmic neutrinos interacting in ice will induce a particle cascade. The Radar Echo Telescope (RET) aims to detect the neutrino through probing the cascade by means of the radar echo method. In order to study this process, we simulate transmitting a radio signal to scatter off the cascade. A return radio signal will be detected at a number of user-defined receivers. Several properties in the radio signals have been observed when systematically varying the direction of the cascade, such as patterns in th…

We introduce a new macroscopic model to simulate in-ice radar detection of high-energy particle\ncascades in dense media. High energy cosmic ray showers impacting a high altitude ice sheet, or\ncosmic neutrinos interacting in the ice produce a high-energy particle cascade, which leaves a\nshort-lived plasma trail composed of ionized ice electrons. Unlike direct radio detection methods,\nthe RET experiment aims to use radar technique to detect the particle cascade via the reflection\nof radio waves off this plasma.…

The SLAC T-576 beam test has shown the radar echo detection method as a feasible technique to probe high-energy-particle-initiated cascades in dense media, such as ice. Furthermore, particle-level simulations show that the radar echo method has a very promising sensitivity to investigate the flux of cosmic neutrinos at energies greater than 1 PeV. Detecting these cosmic neutrinos is the aim of the Radar Echo Telescope for Neutrinos (RET-N). To show the in-nature viability of the radar echo method, we present the R…

The Askaryan Radio Array (ARA) is an in-ice radio detector at the South Pole that targets radio emission from neutrino-induced particle cascades. Designed to detect neutrinos above 10 PeV, ARA has been taking data for over ten years and includes five independent stations. The newest ARA station is equipped with a phased array trigger, which lowers the trigger threshold compared to previous ARA stations and thus increases the neutrino sensitivity. In this contribution, we discuss the newest ARA analysis results fro…

The prototype Schwarzschild-Couder Telescope (pSCT) is a candidate for a medium-sized telescope in the Cherenkov Telescope Array. The pSCT is based on a novel dual mirror optics design which reduces the plate scale and allows for the use of silicon photomultipliers as photodetectors. The prototype pSCT camera currently has only the central sector instrumented with 25 camera modules (1600 pixels), providing a 2.68$^{\circ}$ field of view (FoV). The camera electronics are based on custom TARGET (TeV array readout wi…
