Large-scale Hydrodynamical Shocks as the Smoking Gun Evidence for a Bar in M31
Zi-Xuan Feng, Zhi Li, Juntai Shen +3
The formation and evolutionary history of M31 are closely related to its dynamical structures, which remain unclear due to its high inclination. Gas kinematics could provide crucia…
Gas Dynamics in the Galaxy: Total Mass Distribution and the Bar Pattern Speed
Zhi Li, Juntai Shen, Ortwin Gerhard +1
Gas morphology and kinematics in the Milky Way contain key information for understanding the formation and evolution of our Galaxy. We present a high resolution hydrodynamical simu…
Do nuclear rings in barred galaxies form at the shear minimum of the rotation curve?
Mattia C. Sormani, Zhi Li
It has been recently suggested that (i) nuclear rings in barred galaxies (including our own Milky Way) form at the radius where the shear parameter of the rotation curve reaches a…
Testing the Prediction of Fuzzy Dark Matter Theory in the Milky Way Center
Zhi Li, Juntai Shen, Hsi-Yu Schive
The fuzzy dark matter model (FDM, also known as quantum wave dark matter model) argues that light bosons with a mass of are a possible candidate for dark…
The global stability of M33: still a puzzle
J. A. Sellwood, Juntai Shen, Zhi Li
The inner disc of the local group galaxy M33 appears to be in settled rotational balance, and near IR images reveal a mild, large-scale, two-arm spiral pattern with no strong bar.…
Rapid formation of black holes in galaxies: a self-limiting growth mechanism
Zhi Li, J A Sellwood, Juntai Shen
We present high-quality fluid dynamical simulations of isothermal gas flows in a rotating barred potential. We show that a large quantity of gas is driven right into the nucleus of…
Gas dynamics in the Milky Way: a low pattern speed model
Zhi Li, Ortwin Gerhard, Juntai Shen +2
We present gas flow models for the Milky Way based on high-resolution grid-based hydrodynamical simulations. The basic galactic potential we use is from a N-body model constrained…
Hydrodynamical Simulations of Nuclear Rings in Barred Galaxies
Zhi Li, Juntai Shen, Woong-Tae Kim
Dust lanes, nuclear rings, and nuclear spirals are typical gas structures in the inner region of barred galaxies. Their shapes and properties are linked to the physical parameters…
