Measuring the X-ray luminosities of DESI groups from eROSITA Final Equatorial-Depth Survey: I. X-ray luminosity -- halo mass scaling relation
Yunliang Zheng, Xiaohu Yang, Min He +3
We use the eROSITA Final Equatorial-Depth Survey (eFEDS) to measure the rest-frame 0.1-2.4 keV band X-ray luminosities of 600,000 DESI groups using two different algorithms…
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…
Halo Properties and Mass Functions of Groups/Clusters from the DESI Legacy Imaging Surveys DR9
Jiaqi Wang, Xiaohu Yang, Jun Zhang +16
Based on a large group/cluster catalog recently constructed from the DESI Legacy Imaging Surveys DR9 using an extended halo-based group finder, we measure and model the group-galax…
Groups and protocluster candidates in the CLAUDS and HSC-SSP joint deep surveys
Qingyang Li, Xiaohu Yang, Chengze Liu +16
Using the extended halo-based group finder developed by Yang et al. (2021), which is able to deal with galaxies via spectroscopic and photometric redshifts simultaneously, we const…
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…
