HIR4: Cosmological signatures imprinted on the cross correlation between 21-cm map and galaxy clustering
Feng Shi, Yong-Seon Song, Jacobo Asorey +5
We explore the cosmological multitracer synergies between an emission line galaxy distribution from the Dark Energy Spectroscopic Instrument and a Tianlai Project 21-cm intensity m…
HIR4: cosmology from a simulated neutral hydrogen full sky using Horizon Run 4
Jacobo Asorey, David Parkinson, Feng Shi +6
The distribution of cosmological neutral hydrogen will provide a new window into the large-scale structure of the Universe with the next generation of radio telescopes and surveys.…
Reconstructing simulated CMB polarization power spectra with the Analytical Blind Separation method
Larissa Santos, Jian Yao, Le Zhang +6
Multi-frequency observations are needed to separate the CMB from foregrounds and accurately extract cosmological information from the data. The Analytical Blind Separation (ABS) me…
Testing the ABS method with the simulated Planck temperature maps
Jian Yao, Le Zhang, Yuxi Zhao +3
In this study, we apply the Analytical method of Blind Separation (ABS) of the cosmic microwave background (CMB) from foregrounds to estimate the CMB temperature power spectrum fro…
