Hilbert-Huang Transform analysis of quasi-periodic oscillations in MAXI J1820+070
Wei Yu, Qing-Cui Bu, Zi-Xu Yang +14
We present time-frequency analysis, based on the Hilbert-Huang transform (HHT), of the evolution on the low-frequency quasi-periodic oscillations (LFQPOs) observed in the black hol…
A spectral-timing study of the inner flow geometry in MAXI J1535--571 with -HXMT and NICER
Wei Yu, Qing-Cui Bu, He-Xin Liu +48
We have performed a spectral-timing analysis on the black hole X-ray binary MAXI J1535--571 during its 2017 outburst, with the aim of exploring the evolution of the inner accretion…
An extremely active repeating fast radio burst source in a likely non-magneto-ionic environment
Yi Feng, Di Li, Yong-Kun Zhang +24
Fast radio bursts (FRBs) are bright radio bursts originating at cosmological distances. Only three repeating FRBs FRB 20121102A, FRB 20190520B and FRB 20201124A among 60 kno…
Insight-HXMT and GECAM-C observations of the brightest-of-all-time GRB 221009A
Zheng-Hua An, S. Antier, Xing-Zi Bi +174
GRB 221009A is the brightest gamma-ray burst ever detected since the discovery of this kind of energetic explosions. However, an accurate measurement of the prompt emission propert…
An Insight-HXMT view of the mHz quasi-regular modulation phenomenon in the black hole X-ray binary 4U 1630-47
Zi-Xu Yang, Liang Zhang, Yue Huang +97
Here we report the spectral-timing results of the black hole X-ray binary 4U 1630-47 during its 2021 outburst using observations from the Hard X-ray Modulation Telescope. Type-C qu…
Determination of QPO properties in the presence of strong broad-band noise: a case study on the data of MAXI J1820+070
Deng-Ke Zhou, Shuang-Nan Zhang, Li-Ming Song +8
Accurate calculation of the phase lags of quasi-periodic oscillations (QPOs) will provide insight into their origin. In this paper we investigate the phase lag correction method wh…
