Microscopic Processes in Global Relativistic Jets Containing Helical Magnetic Fields: Dependence on Jet Radius
Ken-Ichi Nishikawa, Yosuke Mizuno, Jose L. Gomez +12
In this study we investigate jet interaction at a microscopic level in a cosmological environment, which responds to a key open question in the study of relativistic jets. Using sm…
Particle-in-cell Simulations of Global Relativistic Jets with Helical Magnetic Fields
Ioana Duţan, Ken-Ichi Nishikawa, Yosuke Mizuno +11
We study the interaction of relativistic jets with their environment, using 3-dimensional relativistic particle-in-cell simulations for two cases of jet composition: (i) electron-p…
Microscopic Processes in Global Relativistic Jets Containing Helical Magnetic Fields
Ken-Ichi Nishikawa, Yosuke Mizuno, Jacek Niemiec +11
In the study of relativistic jets one of the key open questions is their interaction with the environment on the microscopic level. Here, we study the initial evolution of both ele…
Load management strategy for Particle-In-Cell simulations in high energy particle acceleration
Arnaud Beck, Jacob Trier Frederiksen, Julien Dérouillat
In the wake of the intense effort made for the experimental CILEX project, numerical simulation cam- paigns have been carried out in order to finalize the design of the facility an…
Evolution of Global Relativistic Jets: Collimations and Expansion with kKHI and the Weibel Instability
K. I Nishikawa, J. T. Frederiksen, A. Nordlund +10
One of the key open questions in the study of relativistic jets is their interaction with the environment. Here, we study the initial evolution of both electron-proton and electron…
Particle Control in Phase Space by Global K-Means Clustering
J. Trier Frederiksen, G. Lapenta, M. E. Pessah
We devise and explore an iterative optimization procedure for controlling particle populations in particle-in-cell (PIC) codes via merging and splitting of computational macro-part…
