Electron-only reconnection and ion heating in 3D3V hybrid-Vlasov plasma turbulence

Autor: Granier, C., Cerri, S. S., Jenko, F.

We perform 3D3V hybrid-Vlasov simulations of turbulence with quasi-isotropic, compressible injection near ion scales to mimic the Earth's magnetosheath plasma, and investigate the novel electron-only reconnection, recently observed by the NASA's MMS

Gyrofluid simulations of turbulence and reconnection in space plasmas

Autor: Passot, T., Cerri, S. S., Granier, C., Laveder, D., Sulem, P. L., Tassi, E.

Publikováno v: Fundamental Plasma Physics 11 (2024) 100055

A Hamiltonian two-field gyrofluid model is used to investigate the dynamics of an electron-ion collisionless plasma subject to a strong ambient magnetic field, within a spectral range extending from the magnetohydrodynamic (MHD) scales to the electro

Influence of ion-to-electron temperature ratio on tearing instability and resulting subion-scale turbulence in a low-$\beta_e$ collisionless plasma

Autor: Granier, C., Tassi, E., Laveder, D., Passot, T., Sulem, P. L.

A two-field gyrofluid model including ion finite Larmor radius (FLR) corrections, magnetic fluctuations along the ambient field and electron inertia is used to study two-dimensional reconnection in a low $\beta_e$ collisionless plasma, in a plane per

Noncollisional plasmoid instability based on a gyrofluid and gyrokinetic integrated approach

Autor: Granier, C., Numata, R., Borgogno, D., Tassi, E., Grasso, D.

In this work, the development of two-dimensional current sheets with respect to tearing-modes, in collisionless plasmas with a strong guide field, is analysed. During their non-linear evolution, these thin current sheets can become unstable to the fo

In vitro effect of essential oils from Cinnamomum aromaticum, Citrus limon and Allium sativum on two intestinal flagellates of poultry, Tetratrichomonas gallinarum and Histomonas meleagridis

Autor: Zenner L., Callait M.P., Granier C., Chauve C.

Publikováno v: Parasite, Vol 10, Iss 2, Pp 153-157 (2003)

Essential oils may be effective preventive or curative treatments against several flagelated poultry parasites and may become primordial either to organic farms, or as more drugs are bannished. The anti-flagellate activity of essential oils obtained

Linear stability of magnetic vortex chains in a plasma in the presence of equilibrium electron temperature anisotropy

Autor: Granier, C., Tassi, E.

The linear stability of chains of magnetic vortices in a plasma is investigated analytically in two dimensions by means of a reduced fluid model assuming a strong guide field and accounting for equilibrium electron temperature anisotropy. The chain o
