The bright black hole X-ray binary 4U 1543--47 during 2021 outburst: a thick accretion disk inflated by high luminosity
S. J. Zhao, L. Tao, P. P. Li +17
The black hole X-ray binary source 4U 1543--47 experienced a super-Eddington outburst in 2021, reaching a peak flux of up to …
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…
Detection of a strong ~2.5 Hz modulation in the Newly Discovered Millisecond Pulsar MAXI J1816-195
P. P. Li, L. Tao, L. Zhang +16
MAXI J181-195 is a newly discovered accreting millisecond X-ray pulsar that went outburst in June 2022. Through timing analysis with NICER and NuSTAR observations, we find a transi…
A detailed view of low-frequency quasi-periodic oscillation in the broadband 0.2-200 keV with Insight-HXMT and NICER
X. Ma, L. Zhang, L. Tao +13
We report the X-ray timing results of the black hole candidate MAXI J1820+070 during its 2018 outburst using the Hard X-ray Modulation Telescope (Insight-HXMT) and Neutron Star Int…
Timing analysis of EXO 2030+375 during its 2021 giant outburst observed with Insight-HXMT
Yu-Cong Fu, L. M. Song, G. Q. Ding +24
We report the evolution of the X-ray pulsations of EXO 2030+375 during its 2021 outburst using the observations from \textit{Insight}-HXMT. Based on the accretion torque model, we…
Transitions and Origin of the Type-B Quasi-Periodic Oscillation in the Black Hole X-ray Binary MAXI~ J1348--630
H. X. Liu, Y. Huang, Q. C. Bu +26
The fast transitions between different types of quasi-periodic oscillations (QPOs) are generally observed in black hole transient sources (BHTs). We present a detailed study on the…
Probing the Galactic Halo with RR Lyrae Stars. II. The Substructures of the Milky Way
F. Wang, H. -W. Zhang, X. -X. Xue +4
We identify substructures of the Galactic halo using 3,003 type RR Lyraes (RRab) with 6D position-velocity information from the SDSS, LAMOST, and Gaia EDR3. Based on the infor…
Insight-HXMT Detections of Hard X-ray Tails in Scorpius X-1
G. Q. Ding, J. L. Qu, L. M. Song +9
Using the observations of the high-energy (HE) detector of the Hard X-ray Modulation Telescope (Insight-HXMT) for Scorpius X-1 in 2018, we search for hard X-ray tails in the hard X…
