Fast Transitions of X-ray Variability in the Neutron Star Low Mass X-ray Binary Cygnus X-2

Liang Zhang, Mariano Méndez, Hua Feng +12

We present a spectral-timing analysis of two NICER observations of the weakly magnetized neutron star low-mass X-ray binary Cygnus X-2. During these observations, we detect a rapid…

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…

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…
