A Neutron Capture Explanation for the 10 MeV Emission Line Seen in GRB 221009A
Jiahuan Zhu, Hua Feng, Tong Liu
The brightest ever gamma-ray burst (GRB) 221009A displays a significant emission line component around 10 MeV. As the GRB central engine is neutron-rich, we propose that the emissi…
MeV Astrophysical Spectroscopic Surveyor (MASS): A Compton Telescope Mission Concept
Jiahuan Zhu, Xutao Zheng, Hua Feng +19
We propose a future mission concept, the MeV Astrophysical Spectroscopic Surveyor (MASS), which is a large area Compton telescope using 3D position sensitive cadmium zinc telluride…
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 (…
X-ray polarimetry of the Crab nebula with PolarLight: polarization recovery after the glitch and a secular position angle variation
Xiangyun Long, Hua Feng, Hong Li +24
We report follow-up observations of the Crab nebula with the PolarLight X-ray polarimeter, which revealed a possible variation in polarization associated with a pulsar glitch in 20…
