Foreground Characterization and Mitigation in the Observations of the CD/EoR with the SKA
Philip Bull, Jacob Burba, Emilio Ceccotti +20
The Square Kilometre Array (SKA), with its unprecedented sensitivity, frequency coverage, and large collecting area, is poised to revolutionize our understanding of the Cosmic Dawn…
Gravitational Lensing Effects by Galaxy Clusters on Ionised Bubble Size Distribution during the Epoch of Reionisation
Di Wu, Nan Li, Huanyuan Shan +1
The statistical properties of ionisation structures during the Epoch of Reionisation (EoR) provide valuable insights into the formation of the first stars and galaxies. However, si…
MWA and VLA Observations of Diffuse Radio Lobes in M 87
Linhui Wu, Fu-Guo Xie, Qian Zheng +12
This study investigates the projected, quasi-symmetric -scale diffuse radio lobes surrounding the giant elliptical galaxy M\,87, utilizing well-sampled wideband ($\…
MeerKAT discovery of GHz radio emission extending from Abell 3017 toward Abell 3016
Dan Hu, Norbert Werner, Haiguang Xu +18
Context: The clusters Abell 3017 and Abell 3016 are located within a large-scale filament. A prominent X-ray bridge has been detected connecting the two clusters and a potential ga…
A New Model for the Extragalactic Radio Sky at Low Frequency Calibrated Using the LOFAR Two-metre Survey
Jinyang Lin, Zhenghao Zhu, Renyi Ma +2
Building the radio sky template are crucial for detecting the 21 cm emission line signal from the Epoch of Reionization (EoR), as well as for other cosmological research endeavors.…
