Analysis of the plane of satellites around Milky Way- mass galaxies in the IllustrisTNG simulation
Xinghai Zhao, Guobao Tang, Paola Gonzalez +2
It has been suggested that the Plane of Satellites (PoS) phenomenon may imply a tension with current CDM cosmology since a Milky Way (MW)-like PoS is very rare in simulations. I…

Dark Matter and the Early Formation of Supermassive Black Holes
Andrew Imai, Grant J. Mathews, Guobao Tang +1
We investigate the growth of supermassive black holes (SMBHs) at high redshift () from a combination of dark matter capture, black-hole mergers, and gas accretion. It has…

A Study of the Properties and Dynamics of the Disk of Satellites in a Milky-Way-like Galaxy System
Xinghai Zhao, Grant J. Mathews, Lara Arielle Phillips +1
The dynamics of the satellite systems of Milky-Way-like galaxies offer a useful means by which to study the galaxy formation process in the cosmological context. It has been sugges…
