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…
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…
The Three Hundred Project: the evolution of physical baryon profiles
Qingyang Li, Weiguang Cui, Xiaohu Yang +7
The distribution of baryons provides a significant way to understand the formation of galaxy clusters by revealing the details of its internal structure and changes over time. In t…
Late-formed halos prefer to host quiescent central galaxies. I. Observational results
Kai Wang, Yangyao Chen, Qingyang Li +1
The star formation and quenching of central galaxies are regulated by the assembly histories of their host halos. In this work, we use the central stellar mass to halo mass ratio a…
(DarkAI) Mapping the large-scale density field of dark matter using artificial intelligence
Zitong Wang, Feng Shi, Xiaohu Yang +3
Herein, we present a deep-learning technique for reconstructing the dark-matter density field from the redshift-space distribution of dark-matter halos. We built a UNet-architectur…
The impact of halo concentration on the Sunyaev Zel'dovich effect signal from massive galaxy clusters
Eric J. Baxter, Shivam Pandey, Susmita Adhikari +4
The Sunyaev Zel'dovich (SZ) effect is sensitive to the pressure of ionized gas inside galaxy clusters, which is in turn controlled largely by the gravitational potential of the clu…
