Detecting Cosmic 21 cm Global Signal Using an Improved Polynomial Fitting Algorithm
Tianyang Liu, Junhua Gu, Quan Guo +3
Detecting the cosmic 21 cm signal from Epoch of Reionization (EoR) has always been a difficult task. Although the Galactic foreground can be regarded as a smooth power-law spectrum…
The Intensity of Diffuse Galactic Emission Reflected by Meteor Trails
Feiyu Zhao, Ruxi Liang, Zepei Yang +4
We calculate the reflection of diffuse galactic emission by meteor trails and investigate its potential relationship to Meteor Radio Afterglow (MRA). The formula to calculate the r…
Global CD/EoR Signal Detection with a Dense Digital Beamforming Array and Beyond
Junhua Gu, Jingying Wang, Huanyuan Shan +5
The global neutral hydrogen 21 cm signal extracted from the all-sky averaged radio spectra is one of the signatures of the Cosmic Dawn and Epoch of Reionization (CD/EoR). The frequ…
External Calibrator in Global Signal Experiment for Detection of the Epoch of Reionization
Yan Huang, Xiang-Ping Wu, Quan Guo +5
We present a conceptual design study of external calibrators in the 21 cm experiment towards detecting the globally averaged radiation of the epoch of reionization (EoR). Employmen…
Pre-selection of the Candidate Fields for Deep Imaging of the Epoch of Reionization with SKA1-Low
Qian Zheng, Xiang-Ping Wu, Quan Guo +4
The Square Kilometre Array (SKA) will be the first low-frequency instrument with the capability to directly image the structures of the Epoch of Reionization (EoR). Indeed, deep im…
Mass discrepancy in galaxy clusters as a result of the offset between dark matter and baryon distributions
HuanYuan Shan, Bo Qin, HongSheng Zhao
Recent studies of lensing clusters reveal that it might be fairly common for a galaxy cluster that the X-ray center has an obvious offset from its gravitational center which is mea…
