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-…
Narrative Knowledge Weaver: Narrative-Centric Retrieval-Augmented Reasoning for Long-Form Text Understanding
Qiuyu Tian, Fengyi Chen, Yiding Li +9
Long-form narrative QA requires reasoning over evolving story worlds rather than isolated passages: answers may depend on earlier goals, changing character states, social relations…
Modeling the inner part of M87 jet: confronting jet morphology with theory
Hai Yang, Feng Yuan, Hui Li +5
The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole…
Possible role of coronal streamer as magnetically-closed structure in shock-induced energetic electrons and metric type II radio bursts
Xiangliang Kong, Yao Chen, Fan Guo +4
Two solar type II radio bursts, separated by ~24 hours in time, are examined together. Both events are associated with coronal mass ejections (CMEs) erupting from the same active r…
Time-step dependent force interpolation scheme for suppressing numerical Cherenkov instability in relativistic particle-in-cell simulations
Yingchao Lu, Patrick Kilian, Fan Guo +2
The WT scheme, a piecewise polynomial force interpolation scheme with time-step dependency, is proposed in this paper for relativistic particle-in-cell (PIC) simulations. The WT sc…
The Critical Role of Collisionless Plasma Energization on the Structure of Relativistic Magnetic Reconnection
Yi-Hsin Liu, Shan-Chang Lin, Michael Hesse +4
During magnetically dominated relativistic reconnection, inflowing plasma depletes the initial relativistic pressure at the x-line and collisionless plasma heating inside the diffu…
