Pulsar wind nebulae of runaway massive stars
D. M. -A. Meyer, Z. Meliani
A significant fraction of massive stars move at speed through the interstellar medium of galaxies. After their death as core collapse supernovae, a possible final evolutionary stat…
Wide-angle protostellar outflows driven by narrow jets in stratified cores
M. Rabenanahary, S. Cabrit, Z. Meliani +1
Most simulations of outflow feedback on star formation are based on the assumption that outflows are driven by a wide angle "X-wind," rather than a narrow jet. However, the argumen…
Flare echos from relaxation shocks in perturbed relativistic jets
Gaëtan Fichet de Clairfontaine, Zakaria Meliani, Andreas Zech
One of the main scenarios to account for the multi-wavelength flux variability observed in relativistic jets of AGNs is based on diffusive shock acceleration of a population of rel…
Two-wind interactions in binaries with two orbiting giant stars
A. Castellanos-Ramírez, A. Rodríguez-González, Z. Meliani +3
Some red giant envelopes present spiral structures (seen either in dust scattered stellar continuum or in molecular line emission), the most striking example probably being AFGL 30…
Flux variability from ejectas in structured relativistic jets with large-scale magnetic fields
Gaëtan Fichet de Clairfontaine, Zakaria Meliani, Andreas Zech +1
Using the relativistic MHD code MPI-AMRVAC and a radiative transfer code in post-processing, we explore the influence of the magnetic-field configuration and transverse stratificat…
Multi-scale simulations of particle acceleration in astrophysical systems
A. Marcowith, G. Ferrand, M. Grech +3
This review aims at providing an up-to-date status and a general introduction to the subject of the numerical study of energetic particle acceleration and transport in turbulent as…
