Effects of radiative losses on the relativistic jets of high-mass microquasars
A. Charlet, R. Walder, A. Marcowith +3
Context. Relativistic jets are ubiquitous in astrophysics. High Mass Microquasars (HMMQs) are useful labs to study such jets, as they are relatively close and evolve over observabl…
A comparative evaluation of three volume rendering libraries for the visualization of sheared thermal convection
Jean M. Favre, Alexander Blass
Oceans play a big role in the nature of our planet, about of our earth is covered by water. Strong currents are transporting warm water around the world making life possi…
Strong field, scale separated, ultra low viscosity dynamos
Andrey Sheyko, Christopher Finlay, Jean Favre +1
The mechanism by which the Earth's magnetic field is generated is thought to be thermal convection in the metallic liquid iron core. Computational considerations previously restric…
Properties of Cosmological Filaments extracted from Eulerian Simulations
Claudio Gheller, Franco Vazza, Jean Favre +1
Using a new parallel algorithm implemented within the VisIt framework, we analysed large cosmological grid simulations to study the properties of baryons in filaments. The procedur…
The energetics of relativistic magnetic reconnection: ion-electron repartition and particle distribution hardness
Mickaël Melzani, Rolf Walder, Doris Folini +2
Collisionless magnetic reconnection is a prime candidate to account for flare-like or steady emission, outflow launching, or plasma heating, in a variety of high-energy astrophysic…
Simulation of microquasars -- the challenge of scales
Rolf Walder, Mickaël Melzani, Doris Folini +2
We present first results of a long-term project which aims at multi-scale, multi-physics simulations of wind accretion in microquasars and high-mass X-ray binaries. The 3D hydrodyn…
Relativistic magnetic reconnection in collisionless ion-electron plasmas explored with particle-in-cell simulations
Mickaël Melzani, Rolf Walder, Doris Folini +2
Magnetic reconnection is a leading mechanism for magnetic energy conversion and high-energy non-thermal particle production in a variety of high-energy astrophysical objects, inclu…
Supersonic turbulence in 3D isothermal flow collision
Doris Folini, Rolf Walder, Jean M. Favre
Colliding supersonic bulk flows shape observable properties and internal physics of various astrophysical objects, like O-star winds, molecular clouds, galactic sheets, binaries, o…
Knotted Vortices: Entropic Lattice Boltzmann Method for Vortex Dynamics
S. S. Chikatamarla, J. Favre, F. Boesch +1
This fluid dynamics video shows "knotted" vortices in real fluids.
Circum-stellar medium around rotating massive stars at solar metallicity
Cyril Georgy, Rolf Walder, Doris Folini +3
Aims. Observations show nebulae around some massive stars but not around others. If observed, their chemical composition is far from homogeneous. Our goal is to put these observati…
Apar-T: code, validation, and physical interpretation of particle-in-cell results
Mickaël Melzani, Christophe Winisdoerffer, Rolf Walder +4
We present the parallel particle-in-cell (PIC) code Apar-T and, more importantly, address the fundamental question of the relations between the PIC model, the Vlasov-Maxwell theory…
Recurrent Novae: Progenitors of SN Ia?
Rolf Walder, Doris Folini, Jean M. Favre +1
We present 3D hydrodynamical simulations of the separated binary RS Ophiuchi (RS Oph), a recurrent nova and potential progenitor of a SN Ia. RS Oph is composed of a red giant (RG)…
Supersonically Turbulent, Shock Bound Interaction Zones
Doris Folini, Rolf Walder, Jean M. Favre
Shock bound interaction zones (SBIZs) are ubiquitous in astrophysics. We present numerical results for 2D and 3D, plane-parallel, infinitely extended SBIZs. Isothermal settings and…
