abstract = {In the core-collapse scenario, the supernova remnants
evolve inside the complex wind-blown bubbles, structured by
massive progenitors during their lifetime. Therefore,
particle acceleration and the emissions from these SNRs can
carry the fingerprints of the evolutionary sequences of the
progenitor stars. We time-dependently investigate the impact
of the ambient environment of core-collapse SNRs on particle
spectra and the emissions. We use the RATPaC code to model
the particle acceleration at the SNRs with progenitors
having ZAMS masses of 20 Msol and 60 Msol. We have
constructed the pre-supernova circumstellar medium by
solving the hydrodynamic equations for the lifetime of the
progenitor stars. Then, the transport equation for cosmic
rays, and magnetic turbulence in test-particle approximation
along with the induction equation for the evolution of
large-scale magnetic field have been solved simultaneously
with the hydrodynamic equations for the expansion of SNRs
inside the pre-supernova CSM. The structure of the wind
bubbles along with the magnetic field and the scattering
turbulence regulate the spectra of accelerated particles for
both SNRs. For the 60 Msol progenitor the spectral index
reaches 2.4 even below 10 GeV during the propagation of the
SNR shock inside the hot shocked wind. In contrast, we have
not observed persistent soft spectra at earlier evolutionary
stages of the SNR with 20 Msol progenitor, for which the
spectral index becomes 2.2 only for a brief period. Later,
the spectra become soft above ~10 GeV for both SNRs, as weak
driving of turbulence permits the escape of high-energy
particles from the remnants. The emission morphology of the
SNRs strongly depends on the type of progenitors. For
instance, the radio morphology of the SNR with 20 Msol
progenitor is centre-filled at early stages whereas that for
the more massive progenitor is shell-like.},
