The GECKOS survey: Assembly history of the lenticular galaxy NGC 3957
Yuchen Ding, Marie Martig, Ling Zhu +24
We analyse the assembly history of the edge-on lenticular galaxy NGC 3957 using deep integral-field spectroscopic MUSE data from the GECKOS survey. By applying a dust-corrected Mul…
Age, Chemistry, and Kinematics of the Inner Galaxy Revealed by MUSE
Zixian Wang, Michael R. Hayden, Sanjib Sharma +3
The bar/bulge and inner disk are fundamental building blocks of the Milky Way, containing a large fraction of its stellar mass. However, stars in these regions are faint, crowded,…
The GALAH Survey: Stellar parameters and abundances for 800,000 Gaia RVS spectra using GALAH DR4 and The Cannon
Pradosh Barun Das, Daniel B. Zucker, Gayandhi M. De Silva +15
Analysing stellar parameters and abundances from nearly one million Gaia Data Release 3 (DR3) Radial Velocity Spectrometer (RVS) spectra poses challenges due to the limited spectra…
The GALAH survey: Elemental abundances in open clusters using joint effective temperature and surface gravity photometric priors
Kevin L. Beeson, Janez Kos, Richard de Grijs +10
The ability to measure precise and accurate stellar effective temperatures () and surface gravities () is essential in determining accurate and precise abund…
Validating full-spectrum fitting with a synthetic integral-field spectroscopic observation of the Milky Way
Zixian Wang, Michael R. Hayden, Sanjib Sharma +5
Ongoing deep IFS observations of disk galaxies provide opportunities for comparison with the Milky Way (MW) to understand galaxy evolution. However, such comparisons are marred by…
The dawn is quiet here: Rise in [/Fe] is a signature of massive gas accretion that fueled proto-Milky Way
Boquan Chen, Yuan-Sen Ting, Michael Hayden
The proto-Milky Way epoch forms the earliest stars in our Galaxy and sets the initial conditions for subsequent disk formation. Recent observations from APOGEE and H3 surveys showe…
