Energy extraction from a rotating black hole via magnetic reconnection: the plunging bulk plasma and orientation angle

Y Shen, HY YuChih, B Chen - Physical Review D, 2024 - APS
Magnetic reconnection provides a new avenue to extract energy from a rotating black hole in
astrophysical scenarios. There have been many works studying the feasibility of extracting …

Localizing quasiperiodic pulsations in hard X-ray, microwave, and Lyα emissions of an X6. 4 flare

Detection of flare multiperiodic pulsations in mid-ultraviolet Balmer continuum, Lyα, hard X-ray, and radio emissions simultaneously

D Li, M Ge, M Dominique, H Zhao, G Li… - The Astrophysical …, 2021 - iopscience.iop.org
Abstract Quasi-periodic pulsations (QPPs), which usually appear as temporal pulsations of
the total flux, are frequently detected in the light curves of solar/stellar flares. In this study, we …
