IceCube is the world’s largest high-energy neutrino observatory, built at the geographic South Pole. For neutrino astronomy, a large background-free sample of well-reconstructed astrophysical neutrinos is essential. The main backgrounds for this signal are muons and neutrinos, which are produced in cosmic-ray air showers in the Earth’s atmosphere. The coincident detection of these air showers...

Baikal-GVD is a future cubic-kilometer neutrino telescope in Lake Baikal which will be formed by multimegaton subarrays – clusters of strings. Construction of the first GVD-cluster has been started in 2012 by deployment of the first string. The five string array has been deployed in 2014. We review a present activity towards the first cluster implementation and describe some results obtained...

Askaryan Radio Array (ARA) is being built at the South Pole aiming
for observing high energy cosmogenic neutrinos above 10 PeV.
The ARA detector identifies the radio emissions from the excess
charge in a particle shower induced by a neutrino interaction. Such
a radio emission was first predicted by Askaryan in 1962 and
experimentally confirmed by Saltzberg et al. using the SLAC...

In the past decade, searches for the cosmogenic neutrino flux produced by the interactions of ultra-high energy cosmic rays with the cosmic microwave background have not yet resulted in detection. Radio detection of ultra-high energy neutrinos provides a cost-effective means probing large amounts of effective volume. The Antarctic Impulsive Transient Antenna (ANITA) balloon-borne experiment,...

We discuss the feasibility of the radar detection technique as a method for detecting high-energy cosmic neutrinos. When a high-energy neutrino interacts in a dens medium such as ice or rock, a particle cascade will be induced. While traversing through, the cascade will ionize the medium. We discuss the radar detection technique as a probe for the detection of the induced ionization plasma....

The detection of ultra-high energy neutrinos is an important step towards understanding the most energetic cosmic accelerators and would enable tests of fundamental physics at energy scales that cannot be easily achieved on the Earth. Radio detector arrays such as ANITA, ARA, and ARIANNA exploit the Askaryan effect and the radio-transparency of glacial ice, which together enable...
