A Universal Dance of Galactic Disks: Ubiquitous Precession and Its Implications
Yuan Wang, Xiong Luo, Huiyuan Wang +5
Precession is a very common phenomenon for small-scale astronomical objects. However, the precession of galactic disks, occurring on a scale larger than kilo-parsec, has barely bee…
Radio AGN feedback sustains quiescence only in a minority of massive galaxies
Huiling Liu, Yan Lu, Hui Hong +11
Radio active galactic nuclei (AGNs) eject a huge amount of energy into the surrounding medium and are thought to potentially prevent gas cooling and maintain the quiescence of mass…
Physical Processes Behind the Co-Evolution of Halos, Galaxies and Supermassive Black Holes in the IllustrisTNG Simulation
Hao Li, Yangyao Chen, Huiyuan Wang +1
We explore the co-evolution of dark matter halos, their central galaxies, and central supermassive black holes (SMBHs) using the IllustrisTNG (TNG) simulation. We find that the evo…
Unexpected clustering pattern in dwarf galaxies challenges formation models
Ziwen Zhang, Yangyao Chen, Yu Rong +4
The galaxy correlation function serves as a fundamental tool for studying cosmology, galaxy formation, and the nature of dark matter. It is well established that more massive, redd…
