Measuring peculiar velocity and tomographic redshift dipole with DESI DR1 catalogs
Yi-Wen Wu, Jun-Qing Xia
The so-called ``cosmic dipole tension'' challenges the Cosmological Principle by positing a discrepancy between the Solar System's peculiar velocity inferred from the Cosmic Microw…
Probing Cosmic Isotropy with the FAST All Sky HI Survey
Yi-Wen Wu, Jun-Qing Xia
This paper leverages the first released catalog from the FAST All Sky \textsc{Hi} Survey (FASHI) to examine the hypothesis of cosmic isotropy in the local Universe. Given the desig…
Optimal map-making with singularities
Zirui Zhang, Yiwen Wu, Yang Liu +3
In this work, we investigate the optimal map-making technique for the linear system while carefully taking into account singularities that may come from either the covaria…
Study on the filters of atmospheric contamination in ground based CMB observation
Yi-Wen Wu, SiYu Li, Yang Liu +3
The atmosphere is one of the most important contamination sources in the ground-based Cosmic Microwave Background (CMB) observations. In this paper, we study three kinds of filters…
Forecasts on CMB lensing observations with AliCPT-1
Jinyi Liu, Zeyang Sun, Jiakang Han +18
AliCPT-1 is the first Chinese CMB experiment aiming for high precision measurement of Cosmic Microwave Background B-mode polarization. The telescope, currently under deployment in…
