Quasi-periodic oscillations of the X-ray burst from the magnetar SGR J1935+2154 and associated with the fast radio burst FRB 200428
Xiaobo Li, Mingyu Ge, Lin Lin +92
The origin(s) and mechanism(s) of fast radio bursts (FRBs), which are short radio pulses from cosmological distances, have remained a major puzzle since their discovery. We report…
Disk vs wind accretion in X-ray pulsar GX 301-2
Jiren Liu, Long Ji, Peter A. Jenke +8
GX 301-2 provides a rare opportunity to study both disk and wind accretion in a same target. We report Insight-HXMT observations of the spin-up event of GX 301-2 happened in 2019 a…
Insight-HXMT observations of jet-like corona in a black hole X-ray binary MAXI J1820+070
Bei You, Yuoli Tuo, Chengzhe Li +123
A black hole X-ray binary produces hard X-ray radiation from its corona and disk when the accreting matter heats up. During an outburst, the disk and corona co-evolves with each ot…
Insight-HXMT observations of Swift J0243.6+6124 during its 2017-2018 outburst
Yue Zhang, Mingyu Ge, Liming Song +107
The recently discovered neutron star transient Swift J0243.6+6124 has been monitored by {\it the Hard X-ray Modulation Telescope} ({\it Insight-\rm HXMT). Based on the obtained dat…
Diagnosing the kinematics of the tori in active galactic nuclei with the velocity-resolved reverberation mapping of the narrow iron K line
Yuan Liu, Xiaobo Li
The properties of the dusty tori in active galactic nuclei (AGNs) have been investigated in detail, mainly focusing on the geometry and components; however, the kinematics of the t…
The clumpy torus around type II AGN as revealed by X-ray fluorescent lines
Jiren Liu, Yuan Liu, Xiaobo Li +3
The reflection spectrum of the torus around AGN is characterized by X-ray fluorescent lines, which are most prominent for type II AGN. A clumpy torus allows photons reflected from…
A direct comparison of X-ray spectral models for tori in active galactic nuclei
Yuan Liu, Xiaobo Li
Several X-ray spectral models for tori in active galactic nuclei (AGNs) are available to constrain the properties of tori; however, the accuracy of these models has not been verifi…
An X-ray spectral model for clumpy tori in active galactic nuclei
Yuan Liu, Xiaobo Li
We construct an X-ray spectral model for the clumpy torus in an active galactic nucleus (AGN) using Geant4, which includes the physical processes of the photoelectric effect, Compt…
