Geoelectric Field Caused by Flux Transfer Events in an Ionosphere-Coupled Vlasiator Simulation
Konstantinos Horaites, Markku Alho, Yann Pfau-Kempf +10
We report on the relationship between flux transfer events (FTEs) at Earth's magnetopause and the geoelectric field that is induced near the FTEs' magnetic footpoints. We study thi…
Deterministic and probabilistic neural surrogates of global hybrid-Vlasov simulations
Daniel Holmberg, Ivan Zaitsev, Markku Alho +5
Hybrid-Vlasov simulations resolve ion-kinetic effects in the solar wind-magnetosphere interaction, but even 5D (2D + 3V) configurations are computationally expensive. We show that…
Graph-based Neural Space Weather Forecasting
Daniel Holmberg, Ivan Zaitsev, Markku Alho +5
Accurate space weather forecasting is crucial for protecting our increasingly digital infrastructure. Hybrid-Vlasov models, like Vlasiator, offer physical realism beyond that of cu…
Unveiling plasma energization and energy transport in the Earth Magnetospheric System: the need for future coordinated multiscale observations
A. Retino, L. Kepko, H. Kucharek +31
Energetic plasma is everywhere in the Universe. The terrestrial Magnetospheric System is a key case where direct measures of plasma energization and energy transport can be made in…
ULF wave transmission across collisionless shocks: 2.5D local hybrid simulations
Primoz Kajdic, Yann Pfau-Kempf, Lucile Turc +10
We study the interaction of upstream ultra-low frequency (ULF) waves with collisionless shocks by analyzing the outputs of eleven 2D local hybrid simulation runs. Our simulated sho…
Exploring Solar-Terrestrial Interactions via Multiple Observers (A White Paper for the Voyage 2050 long-term plan in the ESA Science Programme)
G. Branduardi-Raymont, M. Berthomier, Y. Bogdanova +24
This paper addresses the fundamental science question: "How does solar wind energy flow through the Earth's magnetosphere, how is it converted and distributed?". We need to underst…
