Establishing HI mass v.s. stellar mass and halo mass scaling relations using an abundance matching method
Yi Lu, Xiaohu Yang, Chengze Liu +5
We combined data from the Sloan Digital Sky Survey (SDSS) and the Arecibo Legacy Fast ALFA Survey (ALFALFA) to establish the HI mass vs. stellar mass and halo mass scaling relation…
Measuring the conditional luminosity and stellar mass functions of galaxies by combining the DESI LS DR9, SV3 and Y1 data
Yirong Wang, Xiaohu Yang, Yizhou Gu +42
In this investigation, we leverage the combination of Dark Energy Spectroscopic Instrument Legacy imaging Surveys Data Release 9 (DESI LS DR9), Survey Validation 3 (SV3), and Year…
The conditional colour-magnitude distribution: II. A comparison of galaxy colour and luminosity distribution in galaxy groups
Haojie Xu, Zheng Zheng, Xiaohu Yang +2
The Conditional Colour-Magnitude Distribution (CCMD) is a comprehensive formalism of the colour-magnitude-halo mass relation of galaxies. With joint modelling of a large sample of…
Connection Between SDSS Galaxies and ELUCID Subhaloes in the Eye of Machine Learning
Xiaoju Xu, Xiaohu Yang, Haojie Xu +1
We explore the feasibility of learning the connection between SDSS galaxies and ELUCID subhaloes with random forest (RF). ELUCID is a constrained -body simulation constructed us…
The clustering of galaxies in the DESI imaging legacy surveys DR8: I. the luminosity and color dependent intrinsic clustering
Zhaoyu Wang, Haojie Xu, Xiaohu Yang +5
In a recent study, we developed a method to model the impact of photometric redshift uncertainty on the two-point correlation function (2PCF). In this method, we can obtain both th…
An Extended Halo-based Group/Cluster finder: application to the DESI legacy imaging surveys DR8
Xiaohu Yang, Haojie Xu, Min He +20
We extend the halo-based group finder developed by \citet[][]{Yang2005a} to use data {\it simultaneously} with either photometric or spectroscopic redshifts. A mock galaxy redshift…
The specific star formation rate function at different mass scales and quenching: A comparison between cosmological models and SDSS
Antonios Katsianis, Haojie Xu, Xiaohu Yang +6
We present the eddington bias corrected Specific Star Formation Rate Function (sSFRF) at different stellar mass scales from a sub-sample of the Sloan Digital Sky Survey Data Releas…
Populating HI gas in dark matter halos: I. method
Yi Lu, Xiaohu Yang, Chengze Liu +4
We combine data from the Sloan Digital Sky Survey (SDSS) and the Arecibo Legacy Fast ALFA Survey (ALFALFA) to establish an empirical model for the HI gas content within dark matter…
The intrinsic SFRF and sSFRF of galaxies: comparing SDSS observation with IllustrisTNG simulation
Ping Zhao, Haojie Xu, Antonios Katsianis +1
The star formation rate function (SFRF) and specific star formation rate function (sSFRF) from the observation are impacted by the Eddington bias, due to the uncertainties on the e…
The Conditional Colour-Magnitude Distribution: I. A Comprehensive Model of the Colour-Magnitude-Halo Mass Distribution of Present-Day Galaxies
Haojie Xu, Zheng Zheng, Hong Guo +3
We formulate a model of the conditional colour-magnitude distribution (CCMD) to describe the distribution of galaxy luminosity and colour as a function of halo mass. It consists of…
Constraining the HI-Halo Mass Relation From Galaxy Clustering
Hong Guo, Cheng Li, Zheng Zheng +5
We study the dependence of galaxy clustering on atomic gas mass using a sample of 16,000 galaxies with redshift in the range of and HI mass of $M_{\rm HI}>10^…
On the Clustering of Faint Red Galaxies
Haojie Xu, Zheng Zheng, Hong Guo +2
Faint red galaxies in the Sloan Digital Sky Survey show a puzzling clustering pattern in previous measurements. In the two-point correlation function (2PCF), they appear to be stro…
