A Semi-Analytical Model for the Formation and Evolution of Radio Relics in Galaxy Clusters
Yihao Zhou, Haiguang Xu, Zhenghao Zhu +8
Radio relics are Mpc-sized synchrotron sources located in the peripheral regions of galaxy clusters. Models based on the diffuse shock acceleration (DSA) scenario have been widely…
The BINGO Project VI: HI Halo Occupation Distribution and Mock Building
Jiajun Zhang, Pablo Motta, Camila P. Novaes +19
BINGO (Baryon Acoustic Oscillations from Integrated Neutral Gas Observations.) is a radio telescope designed to survey from 980 MHz to 1260 MHz, observe the neutral Hydrogen (HI) 2…
The BINGO Project I: Baryon Acoustic Oscillations from Integrated Neutral Gas Observations
Elcio Abdalla, Elisa G. M. Ferreira, Ricardo G. Landim +43
Observations of the redshifted 21-cm line of neutral hydrogen (HI) are a new and powerful window of observation that offers us the possibility to map the spatial distribution of co…
Baryon Acoustic Oscillations from Integrated Neutral Gas Observations: an instrument to observe the 21cm hydrogen line in the redshift range 0.13 z 0.45 -- status update
Carlos A. Wuensche, Elcio Abdalla, Filipe Batoni Abdalla +48
BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making th…
The Merger Dynamics of the Galaxy Cluster Abell 1775: New Insights from Chandra and XMM-Newton for a Cluster Simultaneously Hosting a WAT and a NAT Radio Sources
Dan Hu, Haiguang Xu, Zhenghao Zhu +13
We present a new study of the merger dynamics of Abell~1775 by analyzing the high-quality Chandra and XMM-Newton archival data. We confirm/identify an arc-shaped edge (i.e., the he…
A Study of Gas Entropy Profiles of 47 Galaxy Clusters and Groups Out to the Virial Radius
Zhenghao Zhu, Haiguang Xu, Dan Hu +6
Some observations such as those presented in Walker et al. show that the observed entropy profiles of the intra-cluster medium (ICM) deviate from the power-law prediction of adiaba…
Contribution of Radio Halos to the Foreground for SKA EoR Experiments
Weitian Li, Haiguang Xu, Zhixian Ma +11
The overwhelming foreground contamination is one of the primary impediments to probing the Epoch of Reionization (EoR) through measuring the redshifted 21 cm signal. Among various…
