Revealing an Oscillating and Contracting Compact Corona near the Event Horizon of the Supermassive Black Hole in 1ES 1927+654
Qing-Cang Shui, Shu Zhang, Shuang-Nan Zhang +7
Dynamic processes in the accretion flow near black holes produce X-ray flux variability, sometimes quasi-periodic. Determining its physical origin is key to mapping accretion geome…
Spectral analysis of the X-ray flares in the 2023 outburst of the new black binary transient Swift J1727.8--1613 observed with Insight-HXMT
Jia-Ying Cao, Jin-Yuan Liao, Shuang-Nan Zhang +12
The new black hole transient Swift J1727.8--1613 exhibited a series of X-ray flares during its 2023 outburst extensively observed with Insight-HXMT. We analyze the spectra of the f…
A possible jet and corona configuration for Swift J1727.8--1613 during the hard state
Jing-Qiang Peng, Shu Zhang, Qing-Cang Shui +2
Swift J1727.8--1613 is a black hole X-ray binary that differs from other black hole X-ray binaries in that it has an extra hard component in addition to a reflection component. We…
The peculiar disk evolution of 4U 1630--472 observed by Insight-HXMT during the 2022 and 2023 outbursts
Jing-Qiang Peng, Shu Zhang, Qing-Cang Shui +10
We study the spectral properties of the black hole X-ray transient binary 4U 1630--472 during the 2022 and 2023 outbursts with Insight-HXMT observations. We find that the outbursts…
Insight-HXMT, NICER and NuSTAR views to the newly discovered black hole X-ray binary Swift J151857.0--572147
Jing-Qiang Peng, Shu Zhang, Qing-Cang Shui +10
The systematic properties are largely unknown for the black hole X-ray binary Swift J151857.0--572147 newly discovered in the 2024 outburst. The nature of a black hole can be compl…
NICER, NuSTAR and Insight-HXMT views to black hole X-ray binary SLX 1746--331
Jing-Qiang Peng, Shu Zhang, Qing-Cang Shui +13
We study the spectral and temporal properties of the black hole X-ray transient binary SLX 1746--331 during the 2023 outburst with NICER, NuSTAR, and Insight-HXMT observations. Thr…
NICER, NuSTAR and Insight-HXMT views to the newly discovered black hole X-ray binary Swift J1727.8--1613
Jing-Qiang Peng, Shu Zhang, Qing-Cang Shui +13
Swift J1727.8--1613 is a black hole X-ray binary newly discovered in 2023. We perform spectral analysis with simultaneous Insight-HXMT, NICER and NuSTAR observations when the sourc…
Back to business: SLX 1746--331 after 13 years of silence
Jing-Qiang Peng, Shu Zhang, Peng-Ju Wang +17
The black hole candidate system SLX 1746--331 was back to business in 2023, after a long silence of roughly 13 years. An outburst was observed thoroughly by \textit{Insight}-HXMT a…
Insight-HXMT observations on thermonuclear X-ray bursts from 4U~1608--52 in 2022: the accretion rate dependent anisotropy of burst emission
Yu-Peng Chen, Shu Zhang, Long Ji +10
Thermonuclear X-ray bursts occur on the surface of an accreting neutron star (NS), and their characteristics and interplay with the surrounding circumstance could be a clue to unde…
