Polarization Signatures of Rotating Black Holes in Perfect Fluid Dark Matter Spacetimes
Yu-Xiang Huang, Sen Guo, En-Wei Liang +2
Motivated by horizon-scale polarization observations of M87^{*}, we investigate polarized emission from rotating black holes (BHs) immersed in a perfect fluid dark matter (PFDM) ba…
IXPE view of the Crab pulsar following the 17 July and 6 August 2025 glitches
Paolo Soffitta, Niccolò Bucciantini, Josephine Wong +19
The Crab pulsar experienced two relatively small glitches separated by only 20 days in September and October 2025. IXPE observed the source twice, with delay times since the glitch…
X-Ray Polarization Study of Pulsar Wind Nebulae with eXTP: Simulation Results and Scientific Prospects
Kuan Liu, Fei Xie, Ming-Yu Ge +2
X-ray polarization observations of pulsar wind nebulae (PWNe) provide crucial insights into magnetic field structures and particle acceleration mechanisms. While the Imaging X-ray…
Spatially resolved polarization variation of the Crab Nebula
Chao Zuo, Fei Xie, Mingyu Ge +6
We examined the spatially resolved polarization variations in the Crab Nebula over 2 yr, using observational data from the Imaging X-ray Polarimetry Explorer, and offer key insight…
Energy-resolved polarisation study of the Crab Nebula with IXPE
Wenhao Wei, Fei Xie, Fabio La Monaca +5
This work presents a new detailed study on the energy-dependent variation in the X-ray polarisation of the Crab Pulsar Wind Nebula (PWN), obtained using data from the Imaging X-ray…
Comparison between the emission torus and the measured toroidal magnetic field for the Crab and Vela nebula
Wei Deng, Fei Xie, Kuan Liu +5
Polarization measurements provide insight into the magnetic field, a critical aspect of the dynamics and emission properties around the compact object. In this paper, we present th…
Analysis of Crab X-ray Polarization using Deeper IXPE Observations
Josephine Wong, Tsunefumi Mizuno, Niccoló Bucciantini +98
We present Crab X-ray polarization measurements using IXPE data with a total exposure of 300ks, three times more than the initial 2022 discovery paper. Polarization is detected in…
Two-Component gamma-ray Emission Spectrum and X-Ray Polarization of the Radio Galaxy Pictor A
Jia-Xuan Li, Xin-Ke Hu, Ji-Shun Lian +6
Pictor A is a -ray emitting radio galaxy and has a bright hotspot called WHS, located 4 arcmin away from the nucleus. In this work, we present an analysis of its 16-year F…
Influence of quantum correction on the Schwarzschild black hole polarized image
Sen Guo, Yu-Xiang Huang, Kuan Liu +2
Using a model of an accretion disk around a Schwarzschild black hole, the analytic estimates for image polarization were derived by Narayan . [Astrophys. J, 102, 912 (2021)…
Revisit the Emission Polarization of the Internal-shock for the blazars' Jet
Hao-Qiang Zhang, Da-Bin Lin, Kuan Liu +1
Recent Imaging X-ray Polarimetry Explorer (IXPE) observations of blazars tend to support the shock model for the X-ray emission, but report a low polarization degree ()…
First detection of polarization in X-rays for PSR B0540-69 and its nebula
Fei Xie, Josephine Wong, Fabio La Monaca +100
We report on X-ray polarization measurements of the extra-galactic Crab-like PSR B0540-69 and its Pulsar Wind Nebula (PWN) in the Large Magellanic Cloud (LMC), using a ~850 ks Imag…
A Spatially resolved X-ray Polarization map of the Vela Pulsar Wind Nebula
Kuan Liu, Fei Xie, Yi-Han Liu +12
In this paper, we present a full spatially resolved polarization map for the Vela Pulsar Wind Nebula (PWN) observed by IXPE. By employing effective background discrimination techni…
Highly Significant Detection of X-Ray Polarization from the Brightest Accreting Neutron Star Sco X-1
Fabio La Monaca, Alessandro Di Marco, Juri Poutanen +116
The Imaging X-ray Polarimetry Explorer (IXPE) measured with high significance the X-ray polarization of the brightest Z-source Scorpius X-1, resulting in the nominal 2-8 keV energy…
Discovery of a variable energy-dependent X-ray polarization in the accreting neutron star GX 5-1
Sergio Fabiani, Fiamma Capitanio, Rosario Iaria +116
We report on the coordinated observations of the neutron star low-mass X-ray binary (NS-LMXB) \gx in X-rays (IXPE, NICER, Nustar and INTEGRAL), optical (REM and LCO), near-infrared…
