Phosphorous in the moderately metal-poor bulge globular clusters NGC 6539 and NGC 6569

Morgan S. Camargo, Beatriz Barbuy, Heitor Ernandes +10

The distinct stellar populations of the Galactic bulge can be disentangled through detailed analysis of their chemical abundances and kinematical properties. Recent studies have su…

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…

Parameter Estimation for Open Clusters using an Artificial Neural Network with a QuadTree-based Feature Extractor

L. Cavallo, L. Spina, G. Carraro +7

With the unprecedented increase of known star clusters, quick and modern tools are needed for their analysis. In this work, we develop an artificial neural network trained on synth…

Chrono-chemodynamical analysis of the globular cluster NGC 6355: Looking for the fundamental bricks of the Bulge

Stefano O. Souza, Heitor Ernandes, Marica Valentini +7

The information on Galactic assembly time is imprinted on the chemodynamics of globular clusters. This makes them important probes that help us to understand the formation and evol…

A MUSE study of the inner bulge globular cluster Terzan 9: a fossil record in the Galaxy

H. Ernandes, B. Dias, B. Barbuy +5

Context. Moderately metal-poor inner bulge globular clusters are relics of a generation of long-lived stars that formed in the early Galaxy. Terzan 9, projected at 4d 12 from the G…

Another relic bulge globular cluster: ESO 456-SC38 (Djorgovski~2)

S. Ortolani, E. V. Held, D. Nardiello +7

The object ESO456-SC38 (Djorgovski 2) is one of the globular clusters that is closest to the Galactic center. It is on the blue horizontal branch and has a moderate metallicity of…
