Two-component magnetohydrodynamical outflows around young stellar objects Interplay between stellar magnetospheric winds and disc-driven jets
Z. Meliani, F. Casse, C. Sauty
We present the first-ever simulations of non-ideal magnetohydrodynamical (MHD) stellar magnetospheric winds coupled with disc-driven jets where the resistive and viscous accretion…
Relativistic particle transport in extragalactic jets: I. Coupling MHD and kinetic theory
F. Casse, A. Marcowith
Multidimensional magneto-hydrodynamical (MHD) simulations coupled with stochastic differential equations (SDEs) adapted to test particle acceleration and transport in complex astro…
Postshock turbulence and diffusive shock acceleration in young supernova remnants
A. Marcowith, F. Casse
The present article investigates magnetic amplification in the upstream medium of SNR blast wave through both resonant and non-resonant regimes of the streaming instability. It aim…
A simple toy model for the electromagnetic variability of lump-dominated circumbinary disks around binary black holes
R. Mignon-Risse, P. Varniere, F. Casse
The electromagnetic detection of circumbinary disks around pre-merger binary black holes (BBHs) relies on theoretical predictions. These are generally obtained through expensive nu…
The ECLAIRs micro-satellite mission for gamma-ray burst multi-wavelength observations
S. Schanne, J. -L. Atteia, D. Barret +17
Gamma-ray bursts (GRB), at least those with a duration longer than a few seconds are the most energetic events in the Universe and occur at cosmological distances. The ECLAIRs micr…
Distinguishing an ejected blob from alternative flare models at the Galactic centre with GRAVITY
F. H. Vincent, T. Paumard, G. Perrin +5
The black hole at the Galactic centre exhibits regularly flares of radiation, the origin of which is still not understood. In this article, we study the ability of the near-future…
