Effect of solar proton events on test mass for gravitational wave detection in the 24th solar cycle

Scientific Reports, 2023
Free-falling cubic Test Masses (TMs) are a key component of the interferometer used for low-frequency gravitational wave (GW) detection in space. However, exposure to energetic particles in the environment can lead to electrostatic charging of the TM ...

A New Index to Describe the Response of Geomagnetic Disturbance to the Energy Injection from the Solar Wind

Universe, 2022
In this paper, we establish a new non-dimensional global geomagnetic disturbance index JpG by applying the spectral whitening method to the horizontal components of geomagnetic fields observed at eight ground-based stations distributed at low and middle ...
