Redshift Evolution of the Ratio of Supermassive Black Hole Mass to Stellar Mass
Ziyong Wu, Renyue Cen, Romain Teyssier
We run and analyze a suite of high-redshift zoom-in cosmological simulations with varying supernova feedback and supermassive black hole (SMBH) accretion prescriptions to study the…

Closing the Observational Gap in Cosmic Dynamics: AI-Enabled Reconstruction of the Universe's Vorticity and Rotational Flow Morphology
Ziyong Wu, Xu Xiao, Fuyu Dong +7
The cosmic vorticity field, an essential tracer of nonlinear structure formation, has remained observationally inaccessible because transverse galaxy motions are difficult to measu…

How Fast Could Supermassive Black Holes Grow At the Epoch of Reionization?
Ziyong Wu, Renyue Cen, Romain Teyssier
Utilizing cosmological hydrodynamic simulations we show that there is a brief super-Eddington accretion phase in typical halos at high redshift, impervious to AGN self-regulation.…
