Tomographic Alcock-Paczynski Test with Marked Correlation Functions
Liang Xiao, Limin Lai, Zhujun Jiang +2
The tomographic Alcock-Paczynski(AP) method, developed over the past decade, exploits redshift evolution for cosmological determination, aiming to mitigate contamination from redsh…
Improving SDSS cosmological constraints through -skeleton weighted correlation functions
Fenfen Yin, Jiacheng Ding, Limin Lai +6
The -skeleton approach can be conveniently utilized to construct the cosmic web based on the spatial geometry distribution of galaxies, particularly in sparse samples. This meth…
The PSF Smoothing Effect on Concentration-Related Parameters of High Redshift Galaxies in HST and JWST
Jia-Hui Wang, Zhao-Yu Li, Ming-Yang Zhuang +2
We perform a comprehensive investigation of the PSF smoothing effect on the measurement of concentration-related parameters (, Gini, ) of high redshift galaxies in the H…
Improving Constraint on from SDSS Using Marked Correlation Functions
L. M. Lai, J. C. Ding, X. L. Luo +9
Large-scale structure (LSS) surveys will increasingly provide stringent constraints on our cosmological models. Recently, the density-marked correlation function (MCF) has been int…
