Detecting dark matter substructure with lensed quasars in optical bands
Jianxiang Liu, Kai Liao, Yan Gong
Flux ratios of multiple images in strong gravitational lensing systems provide a powerful probe of dark matter substructure. Optical flux ratios of lensed quasars are typically aff…
Photo- Estimation with Normalizing Flow
Yiming Ren, Kwan Chuen Chan, Le Zhang +6
Accurate photometric redshift (photo-) estimation is a key challenge in cosmology, as uncertainties in photo- directly limit the scientific return of large-scale structure an…
Improving Photometric Redshift Estimation for CSST Mock Catalog Using SED Templates Calibrated with Perturbation Algorithm
Yicheng Li, Liping Fu, Zhu Chen +11
Photometric redshifts of galaxies obtained by multi-wavelength data are widely used in photometric surveys because of its high efficiency. Although various methods have been develo…
Cosmological distance forecasts for the CSST Galaxy Survey using BAO peaks
Feng Shi, Jieyi Tian, Zhejie Ding +21
The measurement of cosmological distances using baryon acoustic oscillations (BAO) is crucial for studying the universe's expansion. The Chinese Space Station Telescope (CSST) gala…
Cosmological Constraints using the Void Size Function Data from BOSS DR16
Yingxiao Song, Yan Gong, Xingchen Zhou +3
We measure the void size function (VSF) from the Baryon Oscillation Spectroscopic Survey (BOSS DR16) and perform the cosmological constraints. The BOSS DR16 galaxy sample is select…
