The large scale structure probes of dark energy
Pengjie Zhang, Shang Li
We present a brief review on the large scale structure (LSS) probes of dark energy. We cover probes that directly constrain dark energy such as baryon acoustic oscillation, redshif…
Reconstructing the Thermal Sunyaev Zeldovich Power Spectrum from Planck using the ABS Method
Zhaoxuan Zhang, Le Zhang, Pengjie Zhang
This study employs a novel approach for reconstructing the thermal Sunyaev-Zeldovich (tSZ) effect power spectrum from Planck data using the Analytical Blind Separation (ABS) method…
Forecast of foreground cleaning strategies for AliCPT-1
Junzhou Zhang, Shamik Ghosh, Jiazheng Dou +18
We report the test results of several independent foreground-cleaning pipelines used in the Ali CMB Polarization Telescope experiment (AliCPT-1), a high-altitude CMB imager in the…
Detector induced anisotropies on the angular distribution of gravitational wave sources and opportunities of constraining horizon scale anisotropies
Mingzheng Li, Pengjie Zhang, Wen Zhao
The cosmological principle has been verified using electromagnetic (EM) observations. However its verification with high accuracy is challenging due to various foregrounds and sele…
Forecasts of CMB lensing reconstruction of AliCPT-1 from the foreground cleaned polarization data
Jiakang Han, Bin Hu, Shamik Ghosh +14
Cosmic microwave background radiation (CMB) observations are unavoidably contaminated by emission from various extra-galactic foregrounds, which must be removed to obtain reliable…
Performance forecasts for the primordial gravitational wave detection pipelines for AliCPT-1
Shamik Ghosh, Yang Liu, Le Zhang +17
AliCPT is the first Chinese cosmic microwave background (CMB) experiment which will make the most precise measurements of the CMB polarization in the northern hemisphere. The key s…
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…
The design of the Ali CMB Polarization Telescope receiver
Maria Salatino, Jason E. Austermann, Keith L. Thompson +72
Ali CMB Polarization Telescope (AliCPT-1) is the first CMB degree-scale polarimeter to be deployed on the Tibetan plateau at 5,250m above sea level. AliCPT-1 is a 90/150 GHz 72 cm…
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…
ABS: an Analytical method of Blind Separation of CMB from foregrounds
Pengjie Zhang, Jun Zhang, Le Zhang
Extracting CMB B-mode polarization from complicated foregrounds is a challenging task in searching for inflationary gravitational waves. We propose the ABS method as a blind and an…
