Ancient relic moderately metal-rich bulge cluster Tonantzintla 2

Sergio Ortolani, Stefano O. Souza, Domenico Nardiello +6

The assembly history of the Galactic bulge is intimately tied to the formation of the proto-Milky Way, yet reconstructing this early phase is difficult because mergers and secular…

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…

Tracing back a second-generation star stripped from Terzan 5 by the Galactic bar

Stefano O. Souza, Marica Valentini, Cristina Chiappini +6

The Galactic bulge hosts the Milky Way's oldest stars, possibly coming from disrupted globular clusters (GCs) or the bulge's primordial building blocks, making these stars witnesse…
