An Insight-HXMT view of the mHz quasi-regular modulation phenomenon in the black hole X-ray binary 4U 1630-47
Zi-Xu Yang, Liang Zhang, Yue Huang +97
Here we report the spectral-timing results of the black hole X-ray binary 4U 1630-47 during its 2021 outburst using observations from the Hard X-ray Modulation Telescope. Type-C qu…
Observatory Science with eXTP
Ping Zhou, Jirong Mao, Liang Zhang +97
Scheduled for launch in 2030, the enhanced X-ray Timing and Polarization (eXTP) telescope is a Chinese space-based mission aimed at studying extreme conditions and phenomena in ast…
A simple, flexible method for timing cross-calibration of space missions
Matteo Bachetti, Yukikatsu Terada, Megumi Shidatsu +25
The timing (cross-)calibration of astronomical instruments is often done by comparing pulsar times-of-arrival (TOAs) to a reference timing model. In high-energy astronomy, the choi…
X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Insight-HXMT observations of Swift J0243.6+6124 during its 2017-2018 outburst
Yue Zhang, Mingyu Ge, Liming Song +107
The recently discovered neutron star transient Swift J0243.6+6124 has been monitored by {\it the Hard X-ray Modulation Telescope} ({\it Insight-\rm HXMT). Based on the obtained dat…
Einstein Probe discovery of EP240408a: a peculiar X-ray transient with an intermediate timescale
Wenda Zhang, Weimin Yuan, Zhixing Ling +136
We report the discovery of a peculiar X-ray transient, EP240408a, by Einstein Probe (EP) and follow-up studies made with EP, Swift, NICER, GROND, ATCA and other ground-based multi-…
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…
The enhanced X-ray Timing and Polarimetry mission -- eXTP for launch in 2030
Shuang-Nan Zhang, Andrea Santangelo, Yupeng Xu +155
In this paper we present the current status of the enhanced X-ray Timing and Polarimetry mission, which has been fully approved for launch in 2030. eXTP is a space science mission…
In-flight Characteristics and Modelling of the Instrumental Background of EP/FXT
Juan Zhang, Yong Chen, Shumei Jia +15
The in-flight instrumental background of the Follow-up X-ray Telescope (FXT) onboard Einstein Probe (EP) mission is analysed in this work by utilizing observations collected during…
Fish Audio S2 Technical Report
Shijia Liao, Yuxuan Wang, Songting Liu +11
We introduce Fish Audio S2, an open-sourced text-to-speech system featuring multi-speaker, multi-turn generation, and, most importantly, instruction-following control via natural-l…
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…
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…
A fast powerful X-ray transient from possible tidal disruption of a white dwarf
Dongyue Li, Wenda Zhang, Jun Yang +97
Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…
New Timing Results of MSPs from NICER Observations
Shijie Zheng, Dawei Han, Heng Xu +10
Millisecond pulsars (MSPs) are known for their long-term stability. Using six years of observations from the Neutron Star Interior Composition Explorer (NICER), we have conducted a…
