Characterizing the temporal evolution of Biermann-battery-driven magnetic reconnection in laser-ablated plasmas

T. Morita, Y. Muramoto, S. Isayama +30

This paper presents an experimental investigation of magnetic reconnection between two laser-produced expanding plasmas, focusing on the quantitative evaluation of the reconnection…

Relativistic multistage resonant and trailing-field acceleration induced by large-amplitude Alfvén waves in a strong magnetic field

S. Isayama, S. Matsukiyo, T. Sano +1

We propose a particle acceleration mechanism driven by large-amplitude Alfvén waves in a strong magnetic field. The acceleration process proceeds through multiple stages triggered…

Evidence for an Inverse Cascade of Magnetic Helicity in the Inner Heliosphere

Masatomi Iizawa, Yasuhito Narita, Tommaso Alberti +6

To elucidate the cascade direction of the solar wind turbulence, we analyzed magnetic helicity density spectra from the Parker Solar Probe data across more than 500 heliocentric di…

Mechanism of generating collisionless shock in magnetized gas plasma driven by laser-ablated target plasma

S. Matsukiyo, K. Oshida, S. Isayama +7

Mechanism of generating collisionless shock in magnetized gas plasma driven by laser-ablated target plasma is investigated by using one-dimensional full particle-in-cell simulation…

Injection process of pickup ion acceleration at an oblique heliospheric termination shock

S. Matsukiyo, Y. Matsumoto

Injection process of pickup ion acceleration at a heliospheric termination shock is investigated. Using two-dimensional fully kinetic particle-in-cell simulation, accelerated picku…
