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…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
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…
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…
The Galactic inner spiral arms revealed by the Gaia ESO Survey chemical abundances. Metallicity and [Mg/Fe] ratios
C. Viscasillas Vázquez, L. Magrini, E. Spitoni +5
Recent observational advances, such as Gaia DR3 GSP-Spec, have highlighted the potential of chemical abundances in tracing and revealing the structure of spiral arms. Building on t…
Tracing the Milky Way spiral arms with 26Al -- The role of nova systems in the 2D distribution of 26Al
Arianna Vasini, Emanuele Spitoni, Francesca Matteucci +2
Massive stars are one of the most important and investigated astrophysical production sites of Al, a short-lived radioisotope with 1 Myr half-life. Its short lifetime…
A Census of Sun's Ancestors and their Contributions to the Solar System Chemical Composition
F. Fiore, F. Matteucci, E. Spitoni +4
In this work we compute the rates and numbers of different types of stars and phenomena (supernovae, novae, white dwarfs, merging neutron stars, black holes) that contributed to th…
NGC1856: Using machine learning techniques to uncover detailed stellar abundances from MUSE data
Randa Asa'd, S. Hernandez, Johina M. John +5
We present the first application of the novel approach based on data-driven machine learning methods applied to Multi-Unit Spectroscopic Explorer (MUSE) field data to derive stella…
2D chemical evolution models II. Effects of multiple spiral arm patterns on O, Eu, Fe and Ba abundance gradients
E. Spitoni, G. Cescutti, A. Recio-Blanco +7
According to observations and numerical simulations, the Milky Way could exhibit several spiral arm modes with multiple pattern speeds, wherein the slower patterns are located at l…
Galactic Archaeology with [Mg/Mn] versus [Al/Fe] abundance ratios -- Uncertainties and caveats
Arianna Vasini, Emanuele Spitoni, Francesca Matteucci
The diagram depicting the abundance ratios [Mg/Mn] vs. [Al/Fe] has gained attention in recent literature as a valuable tool for exploring fundamental aspects of the evolution of th…
Evolution of radioactive elements in the LMC: predictions for future gamma-ray surveys
Arianna Vasini, Francesca Matteucci, Emanuele Spitoni +1
Short-lived radionuclides, such as 26Al and 60Fe, are tracers of star formation. Therefore, their abundances can unravel the recent star formation history of the host galaxy. In vi…
Chemical evolution of Al and Fe in the Milky Way
A. Vasini, F. Matteucci, E. Spitoni
We present theoretical mass estimates of Al and Fe throughout the Galaxy, performed with a numerical chemical evolution model including detailed nucleosynthesis presc…
Heavy element evolution in the inner regions of the Milky Way
F. Matteucci, A. Vasini, V. Grisoni +1
We present results for the evolution of the abundances of heavy elements (O, Mg, Al, Si, K, Ca, Cr, Mn, Ni and Fe) in the inner Galactic regions (kpc). We adopt a detai…
