“…Radio detection addresses a novel approach to unveil the origin, nature and propagation of cosmic rays, high-energy gammas, and neutrinos. The approach can be suitable to develop new and cheaper detection techniques with a large potential for application in the next generation of big experiments either in the Earth's atmosphere or in dielectric materials such as the ice of the polar caps, the salt of [2]. Shown are the primary cosmic ray fluxes (data and a model), the secondary gamma ray flux expected from proton interactions with the CMB and infrared background, and neutrino fluxes (atmospheric ν, galactic ν, AGN ν, and GZK-ν).…”

The ARENA08 conference, held in Rome in June 2008, gave an almost complete overview on applications of the new techniques radio and acoustic detection of electromagnetic showers generated by high-energy cosmic particles in air or in dielectric media. There are vast activities all over the world, and the progress is remarkable. This was displayed by more than 30 contributions to the conference related to the radio detection technique, only. This paper gives a short summary on the status of 'radio detection of particles from the cosmos' as presented at the conference.Key words: radio emission, electromagnetic shower, ultra-high energy cosmic rays, neutrinos PACS: 96.50.S MotivationThe new detection technique of radio observation of highenergy cosmic particles belongs to an innovative field of Astroparticle Physics: The study of high-energy cosmic rays, gamma rays, and neutrinos; i.e. charged as well as neutral particles and nuclei from the cosmos. The goal is to get a coherent physical description of the high-energy, non-thermal Universe. The scientific questions address the understanding of cosmic accelerators and the origin of high-energy cosmic rays. The experimental challenge is to perform multimessenger observations of astrophysical sources. These objects accelerate charged particles and other particles such as neutrinos or gamma rays are produced at reactions with the surrounding media. In addition, due to the unavoidable interaction of very high-energy protons with photons of the microwave background (GZK-effect) secondary neutrinos and gamma rays are produced (see fig. 1).The observation of particles at highest energies is a challenging task. As all cosmic messengers are rare and difficult to detect, the techniques employed require deployment of large area detectors and use of large volume natural detector media (atmosphere, sea water, ice, salt mines, etc.). Presently, the experimental field is entering a new era using large-scale detectors on the surface of the Earth, embedded in the icecap of the Antarctica, or using the deep-sea in the Mediterranean.With the recent results from the Pierre Auger Collaboration [1] of correlations between cosmic ray arrival directions and nearby Active Galactic Nuclei (AGN) a new window to the Universe has been opened. AGN's could be the source of the highest energy cosmic rays, but definite conclusions can be only obtained when the statistical accuracy will be improved at the highest energies and when the information from different messengers (high-energy gamma rays, neutrinos, and hadrons) will be combined.Classical techniques for the detection of cosmic rays are extensive-air-shower observations at ground level by operating large arrays of detectors for charged particles, covering hundreds to thousands of square kilometres. Alternative optical techniques include observations of Cherenkov light in air, water, and ice, as well as observations of fluorescence light from nitrogen molecules in the atmosphere. These techniques are well advanced but become very expens...
