oMEGACat. X. Shedding light on the disrupted dwarf galaxy of Omega Centauri

Stefano Souza, Nadine Neumayer, Anil C. Seth +15

Omega Centauri (Cen) is the most massive and chemically complex star cluster in the Milky Way and is widely regarded as the surviving nuclear star cluster of an accreted dwarf…

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. VII. Tracing Interstellar and Intracluster Medium of Centauri using Sodium Absorptions

Z. Wang, A. C. Seth, M. Latour +14

We investigate the foreground interstellar medium along the line of sight and intracluster medium of Centauri ( Cen) by measuring the equivalent width of Na I D absorptions…

oMEGACat. VI. Analysis of the overall kinematics of Omega Centauri in 3D: velocity dispersion, kinematic distance, anisotropy, and energy equipartition

Maximilian Häberle, Nadine Neumayer, Callie Clontz +15

Omega Centauri ( Cen) is the Milky Way's most massive globular cluster and is likely the stripped nucleus of an accreted dwarf galaxy. In this paper, we analyze Cen's kinema…

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…
