A Novel Approach to 3D Dust Mapping of the Central Molecular Zone
Arianna Vasini, Mattia C. Sormani, Jason L. Sanders +12
The 3D distribution of dust and gas in the Milky Way's Central Molecular Zone (CMZ) is key to understanding gas inflows toward the Galactic Centre (GC), the process of star formati…
Simulations of gas inflow in the Milky Way I. Stellar-Feedback-Regulated Transport from the Central Molecular Zone to the Circumnuclear disk
Zi-Xuan Feng, Mattia C. Sormani, Robin G. Tress +18
We perform hydrodynamical simulations with radially varying resolution to study the effects of stellar feedback on the radial inflow of gas from the Central Molecular Zone (CMZ, $R…
Kinematic hints of a nuclear bar in the Milky Way
Karl Fiteni, Mattia C. Sormani, Victor P. Debattista +8
The Milky Way hosts a flattened nuclear stellar disc (NSD) that dominates the gravitational potential in the inner few hundred parsecs. Whether the NSD is purely axisymmetric or co…
Kinematic diagnostics for non-axisymmetry in the Milky Way's nuclear stellar disc
Karl Fiteni, Xingchen Li, Mattia C. Sormani +8
There is now strong evidence that the Milky Way (MW) hosts a nuclear stellar disc (NSD). However, whether the NSD is purely axisymmetric or contains a nuclear bar remains unresolve…
Metal-Poor Stars in the MW Disk: Resonant Cooling of Vertical Oscillations of Halo Stars in Barred Galaxies
Xingchen Li, Isaac Shlosman, Daniel Pfenniger +1
Using numerical simulations of barred disk galaxy embedded in nonspinning and spinning dark matter (DM) halos, we present a novel mechanism of `cooling' the vertical oscillations o…
Evolution of Stellar Bars in Spinning Dark Matter Halos and Stellar Bulges
Xingchen Li, Isaac Shlosman, Daniel Pfenniger +1
We use high-resolution numerical simulations to follow the barred disk evolution in a suite of models with progressively more massive stellar bulges, with bulge-to-total (diskbu…
Stellar Bars in Spinning Halos: Delayed Buckling and Absence of Slowdown
Xingchen Li, Isaac Shlosman, Clayton Heller +1
We use high resolution numerical simulations in order to analyze the stellar bar evolution in spinning dark matter (DM) halos. Previous works have shown that the halo spin has a su…
The Origin of Buckling Instability in Galactic Bars: Searching for the Scapegoat
Xingchen Li, Isaac Shlosman, Daniel Pfenniger +1
The buckling process in stellar bars is full of unsolved issues. We analyze the origin of the buckling instability in stellar bars using high-resolution N-body simulations. Previou…
