Bayesian Statistical Inversion for High-Dimensional Computer Model Output and Spatially Distributed Counts
Steven D. Barnett, Robert B. Gramacy, Lauren J. Beesley +4
Data collected by the Interstellar Boundary Explorer (IBEX) satellite, recording heliospheric energetic neutral atoms (ENAs), exhibit a phenomenon that has caused space scientists…
Effects of Multi-scale Coupling on Particle Acceleration and Energy Partition in Magnetic Reconnection
Alexander Velberg, Adam Stanier, Xiaocan Li +3
The interplay between kinetic and macroscopic scales during magnetic reconnection is investigated using particle-in-cell simulations of magnetic island coalescence in the strongly-…
Particle Injection Problem in Magnetic Reconnection and Turbulence
Fan Guo, Omar French, Qile Zhang +2
Magnetic reconnection and turbulence in magnetically-dominated environments have been proposed as important nonthermal particle acceleration mechanisms that generate high energy pa…
Modeling of Ionization and Recombination Processes in Plasma with Arbitrary Non-Maxwellian Electron Distributions
Chengcai Shen, Xiaocan Li, Yuan-Kuen Ko +4
In astronomical environments, the high-temperature emission of plasma mainly depends on ion charge states, which requires accurate analysis of the ionization and recombination proc…
Multidisciplinary Science in the Multimessenger Era
Eric Burns, Christopher L. Fryer, Ivan Agullo +82
Astrophysical observations of the cosmos allow us to probe extreme physics and answer foundational questions on our universe. Modern astronomy is increasingly operating under a hol…
Novel Methods for Simulating Astrophysical Plasmas and the Coherent Emission in Fast Radio Bursts
Nicole M. Lloyd-Ronning, Patrick Kilian, Guangye Chen +4
We present particle-in-cell simulations of one dimensional relativistic electromagnetic shocks in a uniform magnetic field, for a range of magnetic field strengths, plasma temperat…
