Energy spectrum of ultrahigh-energy cosmic rays across declinations -90° to +44.8° as measured at the Pierre Auger Observatory
Original language description
The energy spectrum of cosmic rays above 2.5 EeV has been measured across the declination range -90 degrees <= delta <= +44.8 degrees using similar to 310 000 events accrued at the Pierre Auger Observatory from an exposure of (104 900 +/- 3 100) km(2) sr yr. No significant variations of energy spectra with declination are observed, after allowing or not for nonuniformities across the sky arising from the well-established dipolar anisotropies in the arrival directions of ultrahigh-energy cosmic rays. The instep feature in the spectrum at similar or equal to 10 EeV reported previously is now established at a significance above 5 sigma. Within the statistics, the energy spectra are indistinguishable across declinations so disfavoring an origin for the instep from a few distinctive sources.
