Extracting 21cm signal by frequency and angular filtering

21 May 2018Qizhi HuangFengquan WuReza AnsariXuelei Chen

Extracting the neutral hydrogen (HI) signal is a great challenge for cosmological 21cm experiments, both the astrophysical foregrounds and the receiver noise are typically several orders of magnitude greater than the 21cm signal. However, the different properties of the 21cm signal, foreground, and noise can be exploited to separate these components... (read more)
