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…
New insight into the Rapid Burster by Insight-HXMT
Y. P. Chen, S. Zhang, S. N. Zhang +91
We report the timing and spectral analyses upon of the type II X-ray bursts from the Rapid Burster (MXB 1730--335) observed by Insight-HXMT and Swift/XRT. By stacking the long-dura…
A Phase-resolved View of the Low-frequency Quasiperiodic Oscillations from the Black Hole Binary MAXI J1820+070
Qing C. Shui, S. Zhang, Shuang N. Zhang +21
Although low-frequency quasiperiodic oscillations (LFQPOs) are commonly detected in the X-ray light curves of accreting black hole X-ray binaries, their origin still remains elusiv…
Timing properties of the X-ray accreting pulsar RX J0440.9+4431 studied with Insight-HXMT and NICER
P. P. Li, L. Tao, Y. L. Tuo +20
RX J0440.9+4431, a Be/X-ray binary, had its brightest outburst in 2022 since its discovery, with a peak X-ray flux of 2.25 Crab (as recorded by Swift/BAT, 15-50 keV). We analyze th…
X-ray hardening preceding the onset of SGR 1935+2154's radio pulsar phase
Pei Wang, Jian Li, Long Ji +32
Magnetars are neutron stars with extremely strong magnetic fields, frequently powering high-energy activity in X-rays. Pulsed radio emission following some X-ray outbursts have bee…
