(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…
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…
What to expect from dynamical modelling of cluster haloes II. Investigating dynamical state indicators with Random Forest
Qingyang Li, Jiaxin Han, Wenting Wang +5
We investigate the importances of various dynamical features in predicting the dynamical state (DS) of galaxy clusters, based on the Random Forest (RF) machine learning approach. W…
