我们利用预计在21世纪20年代末和30年代初运行的探测器的模拟数据，研究了核心坍缩超新星多维模型的引力波的可探测性和重建。我们发现，与第二代引力波探测器相比，探测距离将提高两倍左右，天空定位将显著改善。我们分析了在250hz截止频率下，超新星信号的低频和高频部分的重建精度。由于波形的峰值频率通常在高频，因此在该频段重构的引力波信号更为精确。
We studied the detectability and reconstruction of gravitational waves from core-collapse supernova multidimensional models using simulated data from detectors predicted to operate in the late 2020s and early 2030s. We found that the detection range will improve by a factor of around two with respect to the second-generation gravitational-wave detectors, and the sky localization will significantly improve. We analyzed the reconstruction accuracy for the lower frequency and higher frequency portion of supernova signals with a 250 Hz cutoff. Since the waveform’s peak frequencies are usually at high frequencies, the gravitational-wave signals in this frequency band were reconstructed more accurately.
