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…
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…
