A Monte Carlo Implementation of Galactic Free-Free Emission for the EoR Foreground Models
Xiaoli Lian, Haiguang Xu, Dongchao Zheng +2
The overwhelming foreground causes severe contamination on the detection of 21-cm signal during the Epoch of Reionization (EoR). Among various foreground components, the Galactic f…

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…

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…
