Unprecedented Central Engine 'Breathing' Phenomenon in an Active Supermassive Black Hole

Autor: Zhou, Shuying, Sun, Mouyuan, Feng, Hai-Cheng, Li, Sha-Sha, Xue, Yongquan, Wang, Jun-Xian, Cai, Zhen-Yi, Bai, Jin-Ming, Li, Danyang, Guo, Hengxiao, Liu, H. T., Lu, Kai-Xing, Mao, Jirong, Marculewicz, Marcin, Wang, Jian-Guo

Resolving the inner structures of active galactic nuclei (AGNs) provides the "standard ruler" to measure the parallax distances of the Universe and a powerful way to weigh supermassive black holes (SMBHs). Thanks to time-domain observations, it is po

On the Detection and Characterization of Quasiperiodic Oscillations in Astronomical Time Series: Gamma-Ray Burst X-Ray Light Curves as a Test Case

Autor: Song, Fei-Fan, Mao, Jirong

The study of temporal properties of variable sources can elucidate their physical processes. In this context, we present a critical study comparing three approaches to periodic or quasiperiodic behavior: Gaussian process, power spectrum, and wavelet

The nature of the minute-to-hour long Fast X-ray Transients (FXTs) localised by telescopes such as Chandra, Swift, and XMM-Newton remains mysterious, with numerous models suggested for the events. Here, we report multi-wavelength observations of EP24
