The chromatic Point Spread Function of weak lensing measurement in Chinese Space Station survey Telescope
Q. Y. Liu, X. Z. Er, Z. H. Fan +6
The weak gravitational lensing is a powerful tool in modern cosmology. To accurately measure the weak lensing signal, one has to control the systematic bias to a small level. One o…
In-orbit performance of LE onboard Insight-HXMT in the first 5 years
Xiaobo Li, Yong Chen, Liming Song +18
Purpose: The Low-Energy X-ray telescope (LE) is a main instrument of the Insight-HXMT mission and consists of 96 Swept Charge Devices (SCD) covering the 1-10 keV energy band. The e…
Measurement of the vertical atmospheric density profile from the X-ray Earth occultation of the Crab Nebula with Insight-HXMT
Daochun Yu, Haitao Li, Baoquan Li +8
In this paper, the X-ray Earth occultation (XEO) of the Crab Nebula is investigated by using the Hard X-ray Modulation Telescope (Insight-HXMT). The pointing observation data on th…
Quasi-periodic oscillations of the X-ray burst from the magnetar SGR J1935+2154 and associated with the fast radio burst FRB 200428
Xiaobo Li, Mingyu Ge, Lin Lin +92
The origin(s) and mechanism(s) of fast radio bursts (FRBs), which are short radio pulses from cosmological distances, have remained a major puzzle since their discovery. We report…
New method for Earth neutral atmospheric density retrieval based on energy spectrum fitting during occultation with LE/\emph{Insight}-HXMT
Daochun Yu, Haitao Li, Baoquan Li +5
We propose a new method for retrieving the atmospheric number density profile in the lower thermosphere, based on the X-ray Earth occultation of the Crab Nebula with the Hard X-ray…
The removal method and generation mechanism of spikes in Insight-HXMT/HE telescope
Baiyang Wu, Yifei Zhang, Xiaobo Li +5
Spikes are some obvious sharp increases that appear on the raw light curves of High Energy X-ray telescope(HE) onboard Insight-HXMT, which could have influences on the data product…
Detection of flare multi-periodic pulsations in mid-ultraviolet Balmer continuum, Ly-alpha, hard X-ray, and radio emissions simultaneously
Dong Li, Mingyu Ge, Marie Dominique +7
Quasi-periodic pulsations (QPPs), which usually appear as temporal pulsations of the total flux, are frequently detected in the light curves of solar/stellar flares. In this study,…
Disk vs wind accretion in X-ray pulsar GX 301-2
Jiren Liu, Long Ji, Peter A. Jenke +8
GX 301-2 provides a rare opportunity to study both disk and wind accretion in a same target. We report Insight-HXMT observations of the spin-up event of GX 301-2 happened in 2019 a…
Insight-HXMT observations of jet-like corona in a black hole X-ray binary MAXI J1820+070
Bei You, Yuoli Tuo, Chengzhe Li +123
A black hole X-ray binary produces hard X-ray radiation from its corona and disk when the accreting matter heats up. During an outburst, the disk and corona co-evolves with each ot…
Comparison of simulated backgrounds with in-orbit observations for HE, ME and LE onboard Insight-HXMT
Juan Zhang, Xiaobo Li, Mingyu Ge +10
Insight-HXMT, the first X-ray astronomical satellite in China, aims to reveal new sources in the Galaxy and to study fundamental physics of X-ray binaries from 1\,keV to 250\,keV.…
