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…

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…

Unveiling the 3D structure of the central molecular zone from stellar kinematics and photometry: The 50 and 20 km/s clouds

Francisco Nogueras-Lara, Ashley T. Barnes, Jonathan D. Henshaw +25

The central molecular zone (CMZ), surrounding the Galactic centre, is the largest reservoir of dense molecular gas in the Galaxy. Despite its relative proximity, the 3D structure o…

Rotation and stability of the circumnuclear gas disk in the Galactic Center potential by the ALMA CMZ Exploration Survey (ACES)

Yoshiaki Sofue, Steven N. Longmore, Daniel Walker +26

We investigated the gravitational potential and mass distribution in the Galactic Center by examining the morphology and kinematics of the circumnuclear gaseous disk revealed by th…

Chemical analysis of the Milky Way's Nuclear Star Cluster: Evidence for a metallicity gradient

M. Schultheis, L. Serrano, B. Thorsbro +5

The Milky Way nuclear star cluster (MWNSC) is located together with its surrounding nuclear stellar disc (MWNSD) in the Galactic centre and they dominate the gravitational potentia…

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…

Kinematic and extinction analysis of a potential spiral arm beyond the Galactic bar

Simran Joharle, Francisco Nogueras-Lara, Karl Fiteni

Determining the structure of the Milky Way is essential for understanding its morphology, dynamics, and evolution. However, studying its innermost regions is challenging due to hig…

The role of density breaks in driving spiral structure in disc galaxies

Karl Fiteni, Sven De Rijcke, Victor P. Debattista +1

It is well established that stellar discs are destabilized by sharp features in their phase space, driving recurrent spiral modes. We explore the extent to which surface-density br…

The relative efficiencies of bars and clumps in driving disc stars to retrograde motion

Karl Fiteni, Joseph Caruana, João A. S. Amarante +2

The presence of stars on retrograde orbits in disc galaxies is usually attributed to accretion events, both via direct accretion, as well as through the heating of the disc stars.…

The Formation of Compact Elliptical Galaxies in The Vicinity of A Massive Galaxy: The Role of Ram-pressure Confinement

Min Du, Victor P. Debattista, Luis C. Ho +9

Compact ellipticals (cEs) are outliers from the scaling relations of early-type galaxies, particularly the mass-metallicity relation which is an important outcome of feedback. The…
