# Vela as the Source of Galactic Cosmic Rays above 100 TeV

## TL;DR

This paper models the Vela supernova remnant's contribution to local cosmic rays above 100 TeV, explaining observed fluxes and their composition by considering anisotropic diffusion and local astrophysical structures.

## Contribution

It introduces a detailed model of Vela's impact on cosmic rays above 100 TeV, incorporating anisotropic diffusion and local bubble effects, which was not previously done.

## Key findings

- Vela significantly contributes to cosmic rays above 100 TeV.
- The combined flux from Vela and a local CR source explains observed spectra.
- Anisotropic diffusion and local structures are crucial in modeling cosmic ray propagation.

## Abstract

We model the contribution of the nearest young supernova remannt Vela to the local cosmic ray flux taking into account both the influence of the Local Superbubble and the effect of anisotropic diffusion. The dominant contribution of this source in the energy region around the cosmic ray knee can naturally explain the observed fluxes of individual groups of nuclei and their total flux. Adding the CR flux from a 2-3 Myr old local CR source suggested earlier, the CR spectra in the whole energy range between 200 GeV and the transition to extragalactic CRs are described well by the combined fluxes from these two local Galactic sources.
