    • Cosmic rays in astrospheres 

      Scherer, K.; Van der Schyff, A.; Ferreira, S.E.S.; Strauss, R.D.; Bomans, D.J. (EDP Sciences, 2015)
      Context: Cosmic rays passing through large astrospheres can be efficiently cooled inside these “cavities” in the interstellar medium. Moreover, the energy spectra of these energetic particles are already modulated in front ...
    • Ionization rates in the heliosheath and in astrosheaths: spatial dependence and dynamical relevance 

      Scherer, K.; Ferreira, S.E.S.; Fichtner, H.; Fahr, H.-J.; Bzowski, M. (EDP Sciences, 2014)
      Context. In the heliosphere, especially in the inner heliosheath, mass-, momentum-, and energy-loading induced by the ionization of neutral interstellar species plays an important, but for some species, especially helium, ...
    • Numerical simulations of composite supernova remnants for small σ pulsar wind nebulae 

      Vorster, M.J.; Ferreira, S.E.S.; De Jager, O.C.; Djannati-Ataï, A. (EDP Sciences, 2013)
      Context. Composite supernova remnants consist of a pulsar wind nebula located inside a shell-type remnant. The presence of a shell has implications on the evolution of the nebula, although the converse is generally not ...
    • Seed photon fields of blazars in the internal shock scenario 

      Joshi, M.; Böttcher, M.; Marscher, A.P. (IOP Publishing, 2014)
      We extend our approach of modeling spectral energy distribution (SED) and light curves of blazars to include external Compton (EC) emission due to inverse Compton scattering of an external anisotropic target radiation ...
