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…
Modeling Atmospheric Ion Escape from Kepler-1649 b and c over Time
Haitao Li, Chuanfei Dong, Lianghai Xie +15
Rocky planets orbiting M-dwarf stars are prime targets for atmospheric characterization, yet their long-term evolution under intense stellar winds and high-energy radiation remains…
Timing and spectral studies of SRGA J144459.2604207 with NICER, Einstein Probe, IXPE, NuSTAR, Insight-HXMT and INTEGRAL during its 2024 outburst
Zhaosheng Li, Lucien Kuiper, Yuanyue Pan +13
SRGA J144459.2604207 is a newly confirmed accreting millisecond X-ray pulsar and type I X-ray burster. We present the broadband X-ray timing and spectral behaviors of SRGA J1444…
A comprehensive study of type I (thermonuclear) bursts in the new transient SRGA J144459.2604207
Tao Fu, Zhaosheng Li, Yuanyue Pan +11
We report an analysis of Insight-HXMT observations of the newly discovered accreting millisecond pulsar SRGA J144459.2604207. During the outburst, detected in 2024 February by S…
