An accretion disc with magnetic outflows triggered by a sudden mass accretion event in changing-look active galactic nucleus 1ES 1927+654
Xinwu Cao, Bei You, Xing Wei
1ES 1927+654 was known as a type 2 Seyfert galaxy, which exhibited drastic variability recently in ultraviolet (UV)/optical and X-ray bands. An UV/optical outburst was observed in…
Observations of a black hole X-ray binary indicate formation of a magnetically arrested disk
Bei You, Xinwu Cao, Zhen Yan +8
Accretion of material onto a black hole drags any magnetic fields present inwards, increasing their strength. Theory predicts that sufficiently strong magnetic fields can halt the…
Application of the disk instability model to all Quasi-Periodic Eruptions
Xin Pan, Shuang-Liang Li, Xinwu Cao
After the first quasi-periodic eruptions (QPEs, GSN069) was reported in 2019, four other sources have been identified as QPEs or its candidate. However, the physics behind QPEs is…
X-ray spectral correlations in a sample of Low-mass black hole X-ray binaries in the hard state
Bei You, Yanting Dong, Zhen Yan +4
The power-law emission and reflection component provide valuable insights into the accretion process around a black hole. In this work, thanks to the broadband spectra coverage of…
A supercritical accretion disk with radiation-driven outflows
Xinwu Cao, Wei-Min Gu
Outflows are inevitably driven from the disk if the vertical component of the black hole (BH) gravity cannot resist the radiation force. We derive the mass loss rate in the outflow…
Analysis of the reflection spectra of MAXI J1535-571 in the hard and intermediate states
Yanting Dong, Zhu Liu, Youli Tuo +4
We report results on the joint-fit of the NuSTAR and HXMT data for the black hole X-ray binary candidate MAXI J1535-571. The observations were obtained in 2017 when the source evol…
