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…
Compact CubeSat Gamma-Ray Detector for GRID Mission
Jia-Xing Wen, Xu-Tao Zheng, Jian-Dong Yu +18
Gamma-Ray Integrated Detectors (GRID) mission is a student project designed to use multiple gamma-ray detectors carried by nanosatellites (CubeSats), forming a full-time all-sky ga…
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…
Modeling the in-orbit background of PolarLight
Jiahui Huang, Hua Feng, Hong Li +23
PolarLight is a gas pixel X-ray polarimeter mounted on a CubeSat, which was launched into a Sun-synchronous orbit in October 2018. We build a mass model of the whole CubeSat with t…
Re-detection and a Possible Time Variation of Soft X-ray Polarisation from the Crab
Hua Feng, Hong Li, Xiangyun Long +24
The Crab nebula is so far the only celestial object with a statistically significant detection in soft x-ray polarimetry, a window that has not been explored in astronomy since the…
In-orbit Operation and Performance of the CubeSat Soft X-ray Polarimeter PolarLight
Hong Li, Xiangyun Long, Hua Feng +21
PolarLight is a compact soft X-ray polarimeter onboard a CubeSat, which was launched into a low-Earth orbit on October 29, 2018. In March 2019, PolarLight started full operation, a…
GRID: a Student Project to Monitor the Transient Gamma-Ray Sky in the Multi-Messenger Astronomy Era
Jiaxing Wen, Xiangyun Long, Xutao Zheng +139
The Gamma-Ray Integrated Detectors (GRID) is a space mission concept dedicated to monitoring the transient gamma-ray sky in the energy range from 10 keV to 2 MeV using scintillatio…
PolarLight: a CubeSat X-ray Polarimeter based on the Gas Pixel Detector
Hua Feng, Weichun Jiang, Massimo Minuti +20
The gas pixel detector (GPD) is designed and developed for high-sensitivity astronomical X-ray polarimetry, which is a new window about to open in a few years. Due to the small mas…
