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…

oMEGACat. VIII. A Subpopulation Census of ω Centauri

C. Clontz, A. C. Seth, Z. Wang +8

An understanding of the assembly history of the complex star cluster Omega Centauri has long been sought after, with many studies separating the stars on the color-magnitude diagra…

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…

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…

oMEGACat III. Multi-band photometry and metallicities reveal spatially well-mixed populations within Centauri's half-light radius

M. S. Nitschai, N. Neumayer, M. Häberle +15

Centauri, the most massive globular cluster in the Milky Way, has long been suspected to be the stripped nucleus of a dwarf galaxy that fell into the Galaxy a long time ago. 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…
