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…
The Low- Splash Population in the Milky Way
Lais Borbolato, João A. S. Amarante, Hélio D. Perottoni +5
The Milky Way in-situ halo, also known as the Splash, consists of old (Age 10 Gyr), metal-rich ([Fe/H] ), high- stars, i.e., thick disk-like chemistry, on halo-like…
Phase spirals induced by the gas warp
Shuyu Wang, Anthony G. A. Brown, Victor P. Debattista +1
The discovery of the phase space spirals in the Solar neighborhood in Gaia Data Release 2 has prompted various attempts to understand their origin. A source of bending waves, which…
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…
Azimuthal metallicity variations, spiral structure, and the failure of radial actions based on assuming axisymmetry
Victor P. Debattista, Tigran Khachaturyants, Joao A. S. Amarante +3
We study azimuthal variations in the mean stellar metallicity, <[Fe/H]>, in a self-consistent, isolated simulation in which all stars form out of gas. We find <[Fe/H]> variations c…
Reply to Comment on "A slightly oblate dark matter halo revealed by a retrograde precessing Galactic disk warp"
Yang Huang, Qikang Feng, Tigran Khachaturyants +7
In this reply, we present a comprehensive analysis addressing the concerns raised by Dehnen et al. (2024) regarding our recent measurement of the disk warp precession using the `mo…
