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 accreting pulsar 1A~0535+262 in the supercritical state with PolarLight
Xiangyun Long, Hua Feng, Hong Li +25
The X-ray pulsar 1A 0535+262 exhibited a giant outburst in 2020, offering us a unique opportunity for X-ray polarimetry of an accreting pulsar in the supercritical state. Measureme…
A significant detection of X-ray Polarization in Sco X-1 with PolarLight and constraints on the corona geometry
Xiangyun Long, Hua Feng, Hong Li +23
We report the detection of X-ray polarization in the neutron star low mass X-ray binary Scorpius (Sco) X-1 with PolarLight. The result is energy dependent, with a non-detection in…
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…
Discrimination of background events in the PolarLight X-ray polarimeter
Jiahuan Zhu, Hong Li, Hua Feng +22
PolarLight is a space-borne X-ray polarimeter that measures the X-ray polarization via electron tracking in an ionization chamber. It is a collimated instrument and thus suffers fr…
