Exploring the Cosmic Reionization Epoch in Frequency Space: An Improved Approach to Remove the Foreground in 21 cm Tomography
Jingying Wang, Haiguang Xu, Tao An +7
Aiming to correctly restore the redshifted 21 cm signals emitted by the neutral hydrogen during the cosmic reionization processes, we re-examine the separation approaches based on…
Kinematics of the Compact Symmetric Object OQ 208 revisited
Fang Wu, Tao An, Willem A. Baan +6
Aims. A long timeline kinematic study of the archetypal CSO OQ 208 sheds light on the physical properties of the most compact radio sources. Methods. Archival data from the VLBA at…
A Method to Extract the Angular Power Spectrum of the Epoch of Reionization from Low-Frequency Radio Interferometers
Qian Zheng, Xiang-ping Wu, Jun-hua Gu +2
The redshifted 21cm signal of neutral hydrogen from the epoch of reionization (EoR) is extremely weak and its first detection is therefore expected to be statistical with first-gen…
Influence of synchrotron self-absorption on the 21cm experiments
Qian Zheng, Xiang-Ping Wu, Jun-Hua Gu +2
Presence of spectral curvature due to synchrotron self-absorption (SSA) of extragalactic radio sources may break down the spectral smoothness feature-the premise that bright radio…
