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…
EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade
R. Alves Batista, M. A. Amin, G. Barenboim +134
Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…
Scissor-cross ionization injection in laser wakefield accelerators
Jia Wang, Ming Zeng, Xiaoning Wang +2
We propose to use a frequency doubled pulse colliding with the driving pulse at an acute angle to trigger ionization injection in a laser wakefield accelerator. This scheme effecti…
On-ground calibrations of the GRID-02 gamma-ray detector
Huaizhong Gao, Dongxin Yang, Jiaxing Wen +12
The Gamma-Ray Integrated Detectors (GRID) are a space project to monitor the transient gamma-ray sky in the multi-messenger astronomy era using multiple detectors on-board CubeSats…
GRB 210121A: A Typical Fireball Burst Detected by Two Small Missions
Xiangyu Ivy Wang, Xutao Zheng, Shuo Xiao +48
The Chinese CubeSat Mission, Gamma Ray Integrated Detectors (GRID), recently detected its first gamma-ray burst, GRB 210121A, which was jointly observed by the Gravitational wave h…
Optimization of Timepix3-based conventional Compton camera using electron track algorithm
Jiaxing Wen, Xutao Zheng, Huaizhong Gao +7
The hybrid pixel detector Timepix3 allows the measurement of the time and energy deposition of an event simultaneously in each 55 m pixel, which makes Timepix3 a promising appro…
Diagnostics for ultrashort X-ray pulses using silicon trackers
Jiaxing Wen, Minghai Yu, Yuchi Wu +8
The spectrum of laser-plasma generated X-rays is very important, it characterizes electron dynamics in plasma and is basic for applications. However, the accuracies and efficiencie…
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…
Radiation Reaction of Betatron Oscillation in Plasma Wakefield Accelerators
Ming Zeng, Keita Seto
A classical model of radiation reaction for the betatron oscillation of an electron in a plasma wakefield accelerator is presented. The maximum energy of the electron due to the lo…
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…
