Modelling cosmic ray electron physics in cosmological smoothed particle hydrodynamics simulation
Dongchao Zheng, Weitian Li, Zhenghao Zhu +5
Cosmic ray electron (CRE) acceleration and cooling are important physical processes in astrophysics. We develop an approximative framework to treat CRE physics in the parallel smoo…

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…

Separating the EoR Signal with a Convolutional Denoising Autoencoder: A Deep-learning-based Method
Weitian Li, Haiguang Xu, Zhixian Ma +7
When applying the foreground removal methods to uncover the faint cosmological signal from the epoch of reionization (EoR), the foreground spectra are assumed to be smooth. However…
