We report the detection of pulsed gamma rays from the Crab pulsar at energies above 100 giga-electron volts (GeV) with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) array of atmospheric Cherenkov telescopes. The detection cannot be explained on the basis of current pulsar models. The photon spectrum of pulsed emission between 100 mega-electron volts and 400 GeV is descri...
The ANTARES Collaboration is currently constructing a large neutrino telescope in the Mediterranean sea. The telescope will use a three-dimensional array of photomultiplier tubes (PMTs) to detect the Cherenkov light emitted in sea water by neutrino-induced muons. The array of 12 strings, which hold 900 PMTs, is planned to be deployed at a depth of about 2500 m near Toulon (France), 40 km off th...
The ANTARES Neutrino Telescope is a water Cherenkov detector composed of an array of approximately 900 photomultiplier tubes in 12 vertical strings, spread over an area of about 0.1 km with an instrumented height of about 350 metres. ANTARES, built in the Mediterranean Sea, is the biggest neutrino telescope operating in the northern hemisphere. Acoustic sensors (AMADEUS project) have been integ...
The southern Pierre Auger Observatory, presently under construction in Malargüe, Ar-gentina, is nearing completion. The instrument is designed to measure extensive air-showers with energies ranging from 10 18-10 20 eV and beyond. It combines two complementary observation techniques; the detection of particles at ground and the coinci-dent observation of associated fluorescence light generated i...
Precise knowledge of all beam parameters is crucial to fully exploit the physics potential of the International Linear Collider (ILC). A sufficiently accurate measurement of the beam polarisation can only be achieved using dedicated high energy Compton polarimeters combined with well-designed Cherenkov detectors. The requirements have been evaluated and a suitable Cherenkov detector prototype h...
Cherenkov telescopes image the Cherenkov emission from air showers. A priori, it is not obvious if the ‘best’ images are achieved by measuring Cherenkov photon angles, i.e. focusing the telescope at infinity, or by considering the air shower as an object to be imaged, in which case one might focus the telescope on the central region of the shower. The issue is addressed using shower simulations...
Since 2004, the Pierre Auger Collaboration has measured, with unprecedented precision, one of most important features ultra-high-energy cosmic rays, energy spectrum. Located in Southern hemisphere, Observatory comprises an array 1660 water-Cherenkov detectors covering 3000 km² overlooked by 27 fluorescence telescopes. Five sets measurements have been used to reconstruct spectrum from 6 PeV beyo...
A theory of pulsar radio emission generation, in which the observed waves are produced directly by maser-type plasma instabilities operating at the anomalous cyclotron-Cherenkov resonance ω − k‖v‖ + ωB/ γres = 0 and the Cherenkov-drift resonance ω − k‖v‖ − k⊥ud = 0, is capable of explaining the main observational characteristics of pulsar radio emission. The instabilities are due to the interac...
