Interpretation of the spectral inhomogeneity in the 10TV region in terms of a close source

TL;DR

This paper models the spectral inhomogeneity at 10 TV in cosmic rays as resulting from a nearby source, estimating its location, age, and energy using a penalty function method.

Contribution

It introduces a novel approach to interpret cosmic ray spectral inhomogeneity through a single close source model with a new localization method.

Findings

Possible source location in space and time identified.

Source energy and age estimated.

Model consistent with experimental spectral data.

Abstract

The description of the inhomogeneity of the cosmic ray spectrum in the region of 10 TV, which is observed in experimental data, in terms of isotropic diffusion from a single close source is considered. It is shown that such a description is possible, the area of possible localization of the source in space and time, its energy is found. The method of penalty functions is used to account for the data on the spectrum of all particles.
