Velocity acoustic oscillations on Cosmic Dawn 21 cm power spectrum as a probe of small-scale density fluctuations
Xin Zhang, Hengjie Lin, Meng Zhang +4
We investigate the feasibility of using the velocity acoustic oscillations (VAO) features on the Cosmic Dawn 21 cm power spectrum to probe small-scale density fluctuations. In the…
The 21-cm forest as a simultaneous probe of dark matter and cosmic heating history
Yue Shao, Yidong Xu, Yougang Wang +4
The absorption features in spectra of high-redshift background radio sources, caused by hyperfine structure lines of hydrogen atoms in the intervening structures, are known collect…
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…
Spectroscopic and Photometric Redshift Estimation by Neural Networks For the China Space Station Optical Survey (CSS-OS)
Xingchen Zhou, Yan Gong, Xian-Min Meng +6
The estimation of spectroscopic and photometric redshifts (spec-z and photo-z) is crucial for future cosmological surveys. It can directly affect several powerful measurements of t…
Cosmology from the Chinese Space Station Optical Survey (CSS-OS)
Yan Gong, Xiangkun Liu, Ye Cao +7
The Chinese Space Station Optical Survey (CSS-OS) is a planned full sky survey operated by the Chinese Space Station Telescope (CSST). It can simultaneously perform the photometric…
Cosmic ray spectrum excess and peak feature observed by the DAMPE experiment from dark matter
Hong-Bo Jin, Bin Yue, Xin Zhang +1
The Chinese satellite Wukong, also known as the DArk Matter Particle Explorer (DAMPE), has released its observation data of the cosmic ray (CR) electrons and positrons. The data sh…
Testing photometric redshift measurements with filter definition of the Chinese Space Station Optical Survey (CSS-OS)
Ye Cao, Yan Gong, Xian-Min Meng +11
The Chinese Space Station Optical Survey (CSS-OS) is a major science project of the Space Application System of the China Manned Space Program. This survey is planned to perform bo…
