It demonstrates the presence of long-range correlations and 1/f fluctuations in cosmic ray data, linking spectral and detrended fluctuation analysis results, which is a novel insight.

Findings

Data exhibits 1/f^{eta} fluctuations with pprox 1

Data shows Brownian fluctuations at high frequency

Long-range correlations confirmed by detrended fluctuation analysis

Abstract

Recent data from the Auger Observatory on low energy secondary cosmic ray particles are analyzed to study temporal correlations together with data on the daily sunspot numbers and neutron monitor data. Standard spectral analysis demonstrates that the available data shows 1/f^{\beta} fluctuations with {\beta} approximately 1 in the low frequency range. All data behave like Brownian fluctuations in the high frequency range. The existence of long-range correlations in the data was confirmed by detrended fluctuation analysis. The real data confirmed the correlation between the scaling exponent of the detrended analysis and the exponent of the spectral analysis.
