Description

In this contribution, I will discuss about a model for the production of cosmic rays from massive, young star clusters present in the Galaxy. I will show that cosmic-ray acceleration at the shocks associated with fast stellar winds of star clusters can produce significant contribution in cosmic rays at energies ~ 10^16 - 10^18 eV. When combined with the contribution from regular supernova remnants in the Galaxy and an extra-galactic component, cosmic-rays from star clusters can reasonably explain the observed all-particle spectrum and composition of cosmic rays.
