CMB delensing with deep learning
Shulei Ni, Yichao Li, Xin Zhang
The cosmic microwave background (CMB) stands as a pivotal source for studying weak gravitational lensing. While the lensed CMB aids in constraining cosmological parameters, it simu…
Cosmology with fast radio bursts in the era of SKA
Ji-Guo Zhang, Ze-Wei Zhao, Yichao Li +3
We present a forecast of the cosmological parameter estimation using fast radio bursts (FRBs) from the upcoming Square Kilometre Array (SKA), focusing on the issues of dark energy,…
FAST drift scan survey for HI intensity mapping: I. preliminary data analysis
Yichao Li, Yougang Wang, Furen Deng +15
This work presents the initial results of the drift-scan observation for the neutral hydrogen (HI) intensity mapping survey with the Five-hundred-meter Aperture Spherical radio Tel…
Fast radio burst energy function in the presence of variation
Ji-Guo Zhang, Yichao Li, Jia-Ming Zou +3
Fast radio bursts (FRBs) have been found in great numbers, but the physical mechanism of these sources is still a mystery. The redshift evolutions of the FRB energy distribution fu…
HI intensity mapping with MeerKAT: forecast for delay power spectrum measurement using interferometer mode
Ming Zhang, Yichao Li, Jing-Fei Zhang +1
Neutral hydrogen (HI) intensity mapping (IM) surveys are considered a promising tool for investigating the expansion history of the Universe. In this work, we explore the potential…
