MAHGIC: A Model Adapter for the Halo-Galaxy Inter-Connection

Yangyao Chen, H. J. Mo, Cheng Li +5

We develop a model to establish the interconnection between galaxies and their dark matter halos. We use Principal Component Analysis (PCA) to reduce the dimensionality of both the…

Finding proto-clusters to trace galaxy evolution: I. The finder and its performance

Kai Wang, H. J. Mo, Cheng Li +1

We develop a method to identify proto-clusters based on dark matter halos represented by galaxy groups selected from surveys of galaxies at high redshift. We test the performance o…

How to empirically model star formation in dark matter halos: I. Inferences about central galaxies from numerical simulations

Yangyao Chen, H. J. Mo, Cheng Li +1

We use TNG and EAGLE hydrodynamic simulations to investigate the central galaxy - dark matter halo relations that are needed for a halo-based empirical model of star formation in g…

Identifying galaxy groups at high redshift from incomplete spectroscopic data: I. The group finder and application to zCOSMOS

Kai Wang, H. J. Mo, Cheng Li +2

Identifying galaxy groups from redshift surveys of galaxies plays an important role in connecting galaxies with the underlying dark matter distribution. Current and future high-

Relating the structure of dark matter halos to their assembly and environment

Yangyao Chen, H. J. Mo, Cheng Li +4

We use a large -body simulation to study the relation of the structural properties of dark matter halos to their assembly history and environment. The complexity of individual h…

The Breakdown Scale of HI Bias Linearity

Zhenyuan Wang, Yangyao Chen, Yi Mao +9

The 21 cm intensity mapping experiments promise to obtain the large-scale distribution of HI gas at the post-reionization epoch. In order to reveal the underlying matter density fl…
