oMEGACat. IX. Chemical Tagging of Omega Centauri Populations with Machine-Learning-Inferred Abundances from the MUSE Spectrograph
Z. Wang, A. C. Seth, C. Clontz +14
We present chemical abundance measurements for 7,302 red giant branch stars within the half-light radius (~5') of Centauri ( Cen), derived from MUSE spectra using the neural…
Orbit-based structural decomposition and stellar population recovery for edge-on barred galaxies
Yunpeng Jin, Ling Zhu, Behzad Tahmasebzadeh +3
In our previous paper, we developed an orbit-superposition method for edge-on barred galaxies and constructed a set of dynamical models based on different mock observations of thre…
Recovering the pattern speeds of edge-on barred galaxies via an orbit-superposition method
Yunpeng Jin, Ling Zhu, Behzad Tahmasebzadeh +4
We developed an orbit-superposition method for edge-on barred galaxies and evaluated its capability to recover the bar pattern speed . We selected three simulated galaxies…
oMEGACat V: Helium Enrichment in Centauri as a Function of Metallicity
C. Clontz, A. C. Seth, Z. Wang +12
Constraining the helium enhancement in stars is critical for understanding the formation mechanisms of multiple populations in star clusters. However, measuring helium variations f…
Rediscovering the Milky Way with orbit superposition approach and APOGEE data III. Panoramic view of the bulge
Sergey Khoperskov, Paola Di Matteo, Matthias Steinmetz +9
The innermost parts of the Milky Way (MW) are very difficult to observe due to the high extinction along the line of sight, especially close to the disc mid-plane. However, this re…
Rediscovering the Milky Way with orbit superposition approach and APOGEE data II. Chrono-chemo-kinematics of the disc
Sergey Khoperskov, Matthias Steinmetz, Misha Haywood +9
The stellar disc is the dominant luminous component of the Milky Way (MW). Although our understanding of its structure is rapidly expanding due to advances in large-scale stellar s…
oMEGACat IV: Constraining Ages of Omega Centauri sub-giant branch stars with HST and MUSE
C. Clontz, A. C. Seth, A. Dotter +13
We present age estimates for over 8100 sub-giant branch (SGB) stars in Omega Centauri ( Cen) to study its star formation history. Our large data set, which combines multi-wavele…
A deep view into the nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. II. Kinematic characterization of the stellar populations
Mayte Alfaro-Cuello, Nikolay Kacharov, Nadine Neumayer +9
The Sagittarius dwarf spheroidal galaxy (Sgr dSph) is in an advanced stage of disruption but still hosts its nuclear star cluster (NSC), M54, at its center. In this paper, we prese…
A deep view into the nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. I. Data and stellar population characterization
Mayte Alfaro-Cuello, Nikolay Kacharov, Nadine Neumayer +9
The center of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) hosts a nuclear star cluster, M54, which is the only galaxy nucleus that can be resolved into individual stars at o…
