GASTRO library II: Exploring Chemical Bimodalities in Disk Galaxies with GSE-like Mergers and Massive Star-forming Clumps
João A. S. Amarante, Chervin F. P. Laporte, Victor P. Debattista +10
We use several smoothed particle hydrodynamics+N-body models as part of the GASTRO library to study the role of high-density star-forming clumpy regions and a single merger on the…
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…
The edge of the Milky Way's star-forming disc: Evidence from a 'U-shaped' stellar age profile
Karl Fiteni, Stuart Robert Anderson, Victor. P. Debattista +7
We leveraged reliable age and distance estimates from LAMOST-DR3 and APOGEE-DR17+AstroNN combined with \gaia\ data to perform a detailed analysis of the stellar age distribution in…
ALMA Central Molecular Zone Exploration Survey (ACES) I: Overview
Steven N. Longmore, John Bally, Ashley T. Barnes +95
The mass flows and energy cycles within the inner regions of galaxies exert a powerful influence on the evolution of the galaxy population. The centre of the Milky Way is the only…
