Cosmic-Ray Events as Background in Imaging Atmospheric Cherenkov Telescopes
The dominant background for observations of γ-rays in the energy region above 50 GeV with Imaging Atmospheric Cherenkov telescopes are cosmic-ray events. The images of most of the cosmic ray showers look significantly different from those of γ-rays and are therefore easily discriminated. However, a small fraction of events seems to be indistinguishable from γ-rays. This constitutes an irreducib...
متن کاملTime Delays in Cosmic Ray Propagation
Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...
متن کاملMeasuring Cosmic Elements with Gamma-Ray Telescopes
Gamma-ray telescopes are capable of measuring radioactive trace isotopes from cosmic nucleosynthesis events. Such measurements address new isotope production rather directly for a few key isotopes such as Ti, Al, Fe, and Ni, as well as positrons from the β-decay variety. Experiments of the past decades have now established an astronomy with γ-ray lines, which is an important part of the study o...
متن کاملThe Cosmic Ray Background as a Tool for Relative Calibration of Atmospheric Cherenkov Telescopes
The atmosphere is an intrinsic part of any ground based Cherenkov γ-ray telescope, and the telescope response is therefore sensitive to unpredictable changes in the atmospheric transparency which are difficult to measure and interpret in the absence of a calibrated beam of high energy γ-rays. In this paper, we use the detector response to Cherenkov emission from cosmic ray initiated air showers...

Ground based Cherenkov γ-ray telescopes are sensitive to unpredictable changes in the atmospheric transparency which are difficult to measure and interpret in the absence of a calibrated beam of high energy γ-rays. We use the detector response to Cherenkov emission from cosmic ray initiated air showers to obtain a relative calibration for data obtained under different instrumental and atmospher...
