Flux Evolution of PSR B0540--69 and the Spectral Energy Distribution of its Pulsar Wind Nebula
Juan Zhang, Xuezhi Liu, Junyang Zhang +12
The young Crab-like pulsar PSR B0540--69, located in the Large Magellanic Cloud, underwent a spin-down rate transition (SRT) in 2011 December, after which its pulsar wind nebula (P…
HESS J1507-622: A Plausible Young Galactic Kilonova Remnant
Prantik Sarmah, Xilu Wang, Myles Carley +3
HESS J1507622 is an unusual TeV gamma-ray source in the H.E.S.S. Galactic Plane Survey, distinguished by its off-plane location () and compact angular ext…
NICER detection of a new candidate cyclotron line in the bursting X-ray pulsar GRO J1744-28
Qi Liu, Lingda Kong, Long Ji +15
We report the detection of cyclotron resonant scattering features (CRSFs) in the spectrum of the unique bursting pulsar GRO J1744-28, observed during its recent outburst in 2021 wi…
Multiwavelength Analysis of PSR J0437-4715 with Pulse Profile Modeling
Liqiang Qi, Juan Zhang, Weiwei Xu +6
We present a multi-wavelength analysis of the nearby millisecond pulsar PSR J0437--4715, combining Hubble Space Telescope (HST) far-ultraviolet, ROSAT soft X-ray, and XMM-Newton X-…
An Intrinsic Degeneracy in a Simplified Semi-Analytic Two-Spot Model for Thermal X-Ray Pulse-Profiles
Tong Zhao, Mingyu Ge, Renxin Xu
We identify an intrinsic degeneracy in the simplified semi-analytic two-spot model for parameter inference in thermal X-ray pulse-profile modeling. Although the exact algebraic deg…
Discovery of energy-dependent phase variations in the polarization angle of Cen X-3
Qing-Chang Zhao, Lian Tao, Sergey S. Tsygankov +7
We present a detailed polarimetric analysis of Cen X-3 using \ixpe observations during its high state, revealing complex energy-dependent polarization behavior. While phase-average…
X-ray and radio observations of the AMXP MAXI J1957+032 covering the 2022-2025 outbursts
Zhaosheng Li, Lucien Kuiper, Yuanyue Pan +12
We presented a comprehensive multi-epoch timing and multiwavelength analysis of the accreting millisecond X-ray pulsar MAXI J1957+032, covering two major outbursts in 2022 and 2025…
Does the radio-active phase of XTE~J1810197 recur following the same evolutionary pattern?
Zhipeng Huang, Zhen Yan, Zhiqiang Shen +12
Magnetars are the most strongly magnetized compact objects known in the Universe and are regarded as one of the primary engines powering a variety of enigmatic, high-energy transie…
