In this study, we present the investigation of nonstationary QPPs with multiple periods during the impulsive phase of a powerful flare on 2017 September 6, which were simultaneously measured by the Hard X-ray Modulation Telescope (Insight-HXMT), as well as the ground-based BLENSW. The multiple periods, detected by applying a wavelet transform and Lomb-Scargle periodogram to the detrended light curves, are found to be ~20-55 s in the Ly`and mid-ultraviolet Balmer continuum emissions during the flare impulsive phase. Similar QPPs with multiple periods are also found in the hard X-ray emission and low-frequency radio emission. Our observations suggest that the flare QPPs could be related to nonthermal electrons accelerated by the repeated energy release process, i.e., triggering of repetitive magnetic reconnection, while the multiple periods might be modulated by the sausage oscillation of hot plasma loops. For the multiperiodic pulsations, other generation mechanisms could not be completely ruled out.   The Hyperluminous, Dust-obscured Quasar W2246–0526 at z?=?4.6: Detection of Parsec-scale Radio Activity 期刊论文  OAI收割 The Astrophysical Journal Letters, 2020, 卷号: 905, 期号: 2 作者:  Fan,Lulu;  Chen,Wen;  An,Tao;  Xie,Fu-Guo;  Han,Yunkun   |  收藏  |  浏览/下载：121/0  |  提交时间：2021/01/25 High-redshift galaxies  Quasars  Radio continuum emission  High-luminosity active galactic nuclei   ALMA Observations of NGC 6334S.
