On the initial spin periods of magnetars born in weak supernova explosions and their gravitational wave radiation
Published 2024-10-01“…Abstract The initial spin periods of newborn magnetars are strongly associated with the origin of their strong magnetic fields, both of which can affect the electromagnetic radiation and gravitational waves (GWs) emitted at their birth. Combining the upper limit $$E_{\textrm{SNR}}\lesssim 10^{51}$$ E SNR ≲ 10 51 erg on the explosion energies of the supernova (SN) remnants around slowly-spinning magnetars with a detailed investigation on the evolution of newborn magnetars, we set constraints on the initial spin periods of magnetars born in weak SN explosions. …”

Three-dimensional numerical simulation and wave field analysis of seismic-while-digging model with faults
Published 2025-06-01“…The results show that the effect of cross-correlation processing of x-component is poor, and the waveform of single shot recording is complete after cross-correlation processing of y-component and z-component; the energy of refracted shear wave and Rayleigh channel wave is strong in the x component, and these two groups of waves interfere with each other in the excavated seismic records, which leads to the poor effect of cross-correlation pulse processing; in y-component, the energy of Love channel wave is strong, and the energy of other wave groups is weak. …”

Propagation characteristics of stress waves induced by underground blasting under the influence of rock-soil interfaces
Published 2025-07-01“…A forward algorithm for the underground blasting vibration field in rock-soil sites was proposed, considering medium damping and geometric diffusion effects of stress waves. Further investigation into the influence of rock and soil parameters and blasting source parameters revealed the following conclusions: stress waves in soil exhibit dispersion, causing peak particle velocity (PPV) to display a discrete distribution. …”
