Estimating a cosmic ray detector exposure sky map under the hypothesis of seasonal and diurnal effects factorization
E. M. Santos, C. Bonifazi, A. Letessier-Selvon
The measurement of large scale patterns or anisotropies in the arrival direction of high energy cosmic rays is an important step towards the understanding of their origin. Such mea…
A coverage independent method to analyze large scale anisotropies
Pierre Billoir, Antoine Letessier-Selvon
The arrival time distribution of cosmic ray events is well suited to extract information regarding sky anisotropies. For an experiment with nearly constant exposure, the frequency…
The trigger system of the Pierre Auger Surface Detector: operation, efficiency and stability
D. Allard, E. Armengaud, I. Allekotte +31
The trigger system of the Surface Detector (SD) of the Pierre Auger Observatory is described, from the identification of candidate showers ( EeV) at the level of a single stat…
A procedure to produce excess, probability and significance maps and to compute point-sources flux upper limits
P. Billoir, A. Letessier-Selvon
A short note to propose a procedure to construct excess maps, probability maps and to calculate point source flux upper limits.
Angular Power Spectrum Estimation of Cosmic Ray Anisotropies with Full or Partial Sky Coverage
O. Deligny, E. Armengaud, T. Beau +5
We study the angular power spectrum estimate in order to search for large scale anisotropies in the arrival directions distribution of the highest-energy cosmic rays. We show that…
Theoretical and Experimental Topics on Ultra High Energy Cosmic Rays
A. Letessier-Selvon
Since their first observation in 1962, the existence of Ultra High Energy Cosmic Rays (UHECR) remains a mystery in modern astrophysics. Those cosmic rays, with energies well above…
