An unbiased method of measuring the ratio of two data sets
Zeyang Sun, Pengjie Zhang, Fuyu Dong +5
In certain cases of astronomical data analysis, the meaningful physical quantity to extract is the ratio between two data sets. Examples include the lensing ratio, the interlop…
Using angular two-point correlations to self-calibrate the photometric redshift distributions of DECaLS DR9
Haojie Xu, Pengjie Zhang, Hui Peng +7
Calibrating the redshift distributions of photometric galaxy samples is essential in weak lensing studies. The self-calibration method combines angular auto- and cross-correlations…
The first direct measurement of gravitational potential decay rate at cosmological scales and improved dark energy constraint
Fuyu Dong, Pengjie Zhang, Zeyang Sun +1
The integrated Sachs-Wolfe (ISW) effect probes the decay rate () of large scale gravitational potential and therefore provides unique constraint on dark energy (DE). However it…
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…
