Probing the Hot Gaseous Halos of Milky Way-like Galaxies in the TNG50 simulation

Zhijie Zhang, Xiaoxia Zhang, Taotao Fang +9

The origin and structure of the hot (K) gaseous halo around Milky Way (MW)-mass galaxies provide a critical test for galaxy formation models. We perform a comprehensi…

The cold molecular gas regulates the activity of active galactic nuclei in massive galaxies

Yongyun Chen, Qiusheng Gu, Luis. C Ho +8

The physical quantities that directly regulate AGN feedback in massive galaxies remain poorly understood. Observations of molecular gas surrounding AGNs suggest that this gas serve…

Causal Reversal in the $M_\unicode{x25CF}\unicode{x2013}σ_0$ Relation: Implications for High-Redshift Supermassive Black Hole Mass Estimates

Benjamin L. Davis, Saakshi More, Zehao Jin +3

The nascent methodology of applying the principles of causal discovery to astrophysical data has produced affirming results about deeply held theories concerning the causal nature…

Tracing the Origins of Hot Halo Gas in Milky Way-Type Galaxies with SMUGGLE

Zhijie Zhang, Xiaoxia Zhang, Hui Li +8

Current galaxy formation models predict the existence of X-ray-emitting gaseous halos around Milky Way (MW)-type galaxies. To investigate properties of this coronal gas in MW-like…

MACER3D -- an upgrade of MACER2D with enhanced subgrid models and gas physics -- and its application to simulating AGN feedback in a massive elliptical galaxy

Haoen Zhang, Haojie Xia, Suoqing Ji +8

We present MACER3D (Multiscale AGN-regulated Cosmic Ecosystem Resolver in 3D), a new suite of three-dimensional hydrodynamic simulations that study active galactic nuclei (AGN) fee…
