First detection of X-ray polarization from the long-period X-ray pulsar 4U 1954+319
Alexander Salganik, Lingda Kong, Sofia V. Forsblom +6
We report the first detection of X-ray polarization with the Imaging X-ray Polarimetry Explorer from the X-ray pulsar (XRP) 4U 1954319. The source belongs to an extremely rare c…
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…
QPOs in a highly magnetized ultra-compact X-ray binary 4U 1626-67
Zi-Yi Zhou, Long Ji, Ling-Da Kong +3
We report the detection of mHz quasi-periodic oscillations (QPOs) in four NuSTAR observations of 4U 1626-67 during its recent spin-down episode. By using a novel method based on th…
Timing and spectral variability in 2S 1417-624 observed with Insight-HXMT
Qi Liu, Lingda Kong, Can Güngör +5
We present the results of the spectral and timing analyses of the accreting X-ray pulsar, 2S 1417-624, during the 2018 and 2021 outbursts with Insight-HXMT. We find that the pulse…
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…
Dimming GRS 1915+105 observed with NICER and Insight--HXMT
M. Zhou, V. Grinberg, A. Santangelo +6
The black hole X-ray binary GRS 1915+105 was bright for 26 years since its discovery and is well-known for its disk instabilities, quasi-periodic oscillations, and disk wind signat…
Timing and spectral studies of the Be/X-ray binary EXO 2030+375 using Insight-HXMT observations
Yu-Jia Du, Lorenzo Ducci, Long Ji +5
We report the X-ray spectral and timing analysis of the high mass X-ray binary EXO 2030+375 during the 2021 type-II outburst based on the Insight-HXMT observations. Pulsations can…
