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…
Chandra Observation of a Weak Shock in the Galaxy Cluster A2556
Zhenzhen Qin, Haiguang Xu, Jingying Wang +3
Based on a 21.5 ks \chandra\ observation of A2556, we identify an edge on the surface brightness profile (SBP) at about 160 kpc northeast of the cluster center, and it…
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…
Two-Phase ICM in the Central Region of the Rich Cluster of Galaxies Abell 1795: A Joint Chandra, XMM-Newton, and Suzaku View
Liyi Gu, Haiguang Xu, Junhua Gu +7
Based on a detailed analysis of the high-quality Chandra, XMM-Newton, and Suzaku data of the X-ray bright cluster of galaxies Abell 1795, we report clear evidence for a two-phase i…
