This is the report on the cosmic ray direct track of the 37th International Cosmic Ray Conference (ICRC 2021), broadly covering the contributions relating to charged cosmic rays (CRs) of Galactic origin. The contributions highlighted here are of both observational and theoretical nature and aim at interpreting the local fluxes of CRs as well as studying the wider dynamical effects of CRs. New data from space-borne experiments on CR electrons and positrons, proton and helium as well as heavier…

Status of Ground-based and Galactic Gamma-ray Astronomy
This conference proceedings is a write-up of the Gamma-ray Indirect rapporteur talk given at the 37th International Cosmic Ray Conference (ICRC 2021). In contrast to previous ICRCs, this years
Cosmic-ray variations in the solar neighbourhood
The γ radiation produced in cosmic-ray and gas interactions has been used to probe the local cosmic-ray spectrum in several clouds to distances of ∼1 kpc around the Sun. Early measurements made with
Anisotropy of Protons and Light Primary Nuclei in Cosmic Rays Measured with the Alpha Magnetic Spectrometer on the ISS
A measurement of the cosmic ray anisotropy on the arrival directions of protons and light primary nuclei (helium, carbon and oxygen) has been performed in galactic coordinates by the Alpha Magnetic

Investigating the Vela SNR's Emission of Electron Cosmic Rays with CALET at the International Space Station
The ISS-based Calorimetric Electron Telescope (CALET) is directly measuring the energy spectrum of electron+positron cosmic rays up to 20 TeV. Cosmic-ray electrons of TeV region energy are limited by

Despite significant progress over more than 100 years, no accelerator has been unambiguously identified as the source of the locally measured flux of cosmic rays. High-energy electrons and positrons
Measurement of cosmic-ray electrons at TeV energies by VERITAS
Cosmic-ray electrons and positrons (CREs) at GeV-TeV energies are a unique probe of our local Galactic neighborhood. CREs lose energy rapidly via synchrotron radiation and inverse-Compton scattering
Interstellar cosmic-ray spectra (1) just outside the heliosphere and (2) in the local medium: are they the same?

Interstellar cosmic ray (CR) spectra just outside the heliosphere are accessible thanks to direct measurements of CR, with uncertainties given by the solar modulation. Interstellar CR spectra in the
The Origin of Galactic Cosmic Rays as Revealed by their Composition
Galactic cosmic-rays (GCRs) are thought to be accelerated in strong shocks induced by massive star winds and supernova explosions sweeping across the interstellar medium. But the phase of the
