Weak Evolution of Cosmic Atomic Hydrogen over the Past 4.5 Billion Years

Chuan-Peng Zhang, Hong Guo, Yizhou Gu +49

The cosmic star formation rate density (CSFRD) has declined sharply toward the present day, but the roles of the atomic and molecular gas reservoirs remain uncertain. We measure th…

Investigating the residuals in the relation using the SIMBA cosmological simulation

Wenlin Ma, Weiguang Cui, Romeel Davé +2

We study the scaling relation between the black hole and stellar mass (), diagnosing the residual () in this relation to understand t…

The HI Mass Function of the Local Universe: Combining Measurements from HIPASS, ALFALFA and FASHI

Wenlin Ma, Hong Guo, Haojie Xu +6

We present the first HI mass function (HIMF) measurement for the recent FAST All Sky HI (FASHI) survey and the most complete measurements of HIMF in the local universe thus far. We…

NeutralUniverseMachine: Predictions of HI gas in Different Theoretical Models

Lingkun Wen, Hong Guo, Wenlin Ma +4

We investigate the distribution and evolution of HI gas in different theoretical models, including hydro-dynamical simulations (Illustris-TNG and SIMBA), semi-analytic models (GAEA…
