Microwave beam broadening due to turbulent plasma density fluctuations within the limit of the Born approximation and beyond
Alf Köhn, Lorenzo Guidi, Eberhard Holzhauer +4
Plasma turbulence, and edge density fluctuations in particular, can under certain conditions broaden the cross-section of injected microwave beams significantly. This can be a seve…
Fast matrix-free evaluation of discontinuous Galerkin finite element operators
Martin Kronbichler, Katharina Kormann
We present an algorithmic framework for matrix-free evaluation of discontinuous Galerkin finite element operators based on sum factorization on quadrilateral and hexahedral meshes.…
Infrared Selection of Obscured Active Galactic Nuclei in the COSMOS Field
Yu-Yen Chang, Emeric Le Floc'h, Stéphanie Juneau +13
We present a study of the connection between black hole accretion, star formation, and galaxy morphology at z<=2.5. We focus on active galactic nuclei (AGNs) selected by their mid-…
Fully Kinetic Simulation of 3D Kinetic Alfven Turbulence
D. Groselj, A. Mallet, N. F. Loureiro +1
We present results from a three-dimensional particle-in-cell simulation of plasma turbulence, resembling the plasma conditions found at kinetic scales of the solar wind. The spectr…
Saturation of energetic-particle-driven geodesic acoustic modes due to wave-particle nonlinearity
A. Biancalani, I. Chavdarovski, Z. Qiu +6
The nonlinear dynamics of energetic-particle (EP) driven geodesic acoustic modes (EGAM) is investigated here. A numerical analysis with the global gyrokinetic particle-in-cell code…
Stable evaluation of Gaussian radial basis functions using Hermite polynomials
Anna Yurova, Katharina Kormann
Gaussian radial basis functions can be an accurate basis for multivariate interpolation. In practise, high accuracies are often achieved in the flat limit where the interpolation m…
