The NANOGrav collaboration has recently reported evidence for the existence of a stochastic gravitational wave background in 1-100 nHz frequency range. We argue that such could have been produced by magneto-hydrodynamic (MHD) turbulence at QCD scale. From measurement one can infer magnetic field parameters: comoving strength close to microGauss and correlation length 10\% Hubble radius phase tr...

We present a STRUcture-Preserving HYbrid code - STRUPHY for the simulation of magneto-hydrodynamic (MHD) waves interacting with population energetic particles far from thermal equilibrium (kinetic species). The implemented model features linear, ideal MHD equations in curved, three-dimensional space, coupled nonlinearly to full-orbit Vlasov via current coupling scheme. algorithm is based on fin...

Rotating outflows from protostellar disks might trace extended magneto-hydrodynamic (MHD) disk winds (DWs), providing a solution to the angular momentum problem in accretion for star formation. In jet system HH 212, rotating outflow was detected SO around an episodic SiO. Here we spatially resolve this into three components: collimated aligned with SiO jet, wide-angle outflow, and evacuated cav...

In this paper, we present an entropy-stable Gauss collocation discontinuous Galerkin (DG) method on 3D curvilinear meshes for the GLM-MHD equations: single-fluid magneto-hydrodynamics (MHD) equations with a generalized Lagrange multiplier (GLM) divergence cleaning mechanism. For continuous entropy analysis to hold and ensure Galilean invariance in technique, system requires use of non-conservat...

Abstract Recent studies suggest that the magnetic field may play an important role in formation of giant planets during final stage process. In this paper, we construct a circumplanetary system around planet is to investigate effects planetary on accretion process at stage. We find early times our magneto-hydrodynamic (MHD) simulation, loops connecting and material inflate upward due build-up t...

We present results from an extensive survey of 64 cavities in the X-ray halos of clusters, groups and normal elliptical galaxies. We show that the evolution of the size of the cavities as they rise in the X-ray atmosphere is inconsistent with the standard model of adiabatic expansion of purely hydrodynamic models. We also note that the majority of the observed bubbles should have already been s...

A magneto-hydrodynamic (MHD) stirrer that exhibits chaotic advection is designed, modeled, and tested. The stirrer can operate as a stand-alone component or it can be incorporated into a MHD-controlled network. The stirrer consists of a conduit equipped with individually controlled electrodes positioned along its opposing walls. The conduit is filled with an electrolyte solution and positioned ...

Density pumpout and edge-localized mode (ELM) suppression by applied n=2 magnetic fields in low-collisionality DIII-D plasmas are shown to be correlated with the magnitude of the plasma response driven on the high-field side (HFS) of the magnetic axis but not the low-field side (LFS) midplane. These distinct responses are a direct measurement of a multimodal magnetic plasma response, with each ...
