Efficient ion re-acceleration in laboratory-produced interpenetrating collisionless shocks

W. Yao, I. Cohen, P. Suarez Gerona +20

Although the origin of cosmic rays (CRs) remains an open question, collisionless magnetized shock waves are widely regarded as key sites for particle acceleration. Recent theories…

Cosmic rays: constraints from future MeV detectors

Giada Peron, Sarah Recchia, Stefano Menchiari +4

Cosmic rays are charged energetic particles that permeate the interstellar medium. Their sizeable energy share and penetration power makes them essential players in the dynamical a…

The Rayleigh Taylor instability in partially ionized plasmas: ambipolar diffusion effects in the non linear phase

E. Callies, Z. Meliani, A. Marcowith +1

Aims. We aim to determine how ion neutral coupling and ambipolar diffusion affect the linear and the nonlinear growth of the RTinstability under astrophysically relevant conditions…

RAMSES-MCR: A consistent multi-group treatment of cosmic rays physics in momentum-space with the RAMSES code

Nimatou-Seydi Diallo, Yohan Dubois, Alexandre Marcowith +2

Cosmic rays (CRs) are known to play a key role in many astrophysical environments: they can modify shock dynamics, influence the thermochemistry and the ionization of the interstel…

Towards the Giant Radio Array for Neutrino Detection (GRAND): the GRANDProto300 and GRAND@Auger prototypes

GRAND Collaboration, Jaime Álvarez-Muniz, Rafael Alves Batista +118

The Giant Radio Array for Neutrino Detection (GRAND) is a proposed multi-messenger observatory of Ultra-High-Energy (UHE) particles of cosmic origin. Its main goal is to find the l…

JWST imaging of the Pleiades: anisotropy of turbulence in the cold neutral medium

G. Vigoureux, N. Flagey, F. Boulanger +14

Interstellar medium studies rely on magnetohydrodynamic (MHD) turbulence as a framework for interpretation. In this context, the statistical characterization of interstellar observ…
