X-ray Polarimetry in the Low Statistics Regime using the Bayesian Approach Reveals Polarization Angle Variations
Hong Li, Qing-Chang Zhao, Hua Feng +2
X-ray polarimetry of accreting compact objects has revealed fast time variations in the polarization angle (PA), suggesting that the geometry and/or optical depth of the Comptoniza…
Investigating Primordial Black Hole Accretion through Cosmic Optical Depth
Zi-Xuan Zhang, Junsong Cang, Yu Gao +1
Primordial black holes (PBH) accretion in the late Universe can lead to significant mass growth. A larger mass further accelerates the accretion radiation output for PBHs with init…
Discovery of Rapid Polarization Angle Variation During the 2022 Outburst of XTE J1701-462
QingChang Zhao, Hong Li, Lian Tao +1
The geometry of the Comptonization corona in neutron star low-mass X-ray binaries is still unclear. We conducted time-resolved polarimetric analysis of the archival observations of…
Research on the X-Ray Polarization Deconstruction Method Based on Hexagonal Convolutional Neural Network
Ya-Nan Li, Jia-Huan Zhu, Huai-Zhong Gao +5
Track reconstruction algorithms are critical for polarization measurements. In addition to traditional moment-based track reconstruction approaches, convolutional neural networks (…
