HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
MgAl burning chain in M 54: the globular cluster-like properties of a nuclear star cluster
D. A. Alvarez Garay, A. Mucciarelli, P. Ventura +2
In this study, we present the chemical abundances of Fe, Mg, Al, Si, and K for a sample of 233 likely member stars of M 54. All the stars were observed with the FLAMES high-resolut…
HST+IGRINS synergy to characterise the newly discovered metal-rich bulge globular cluster Patchick 126
Elisa R. Garro, Davide Massari, José G. Fernández-Trincado +10
We present the first comprehensive spectroscopic and deep photometric study of the globular cluster (GC) candidate Patchick~126. The spectroscopic analysis is based on high-resolut…
The Hubble Missing Globular Cluster Survey. II. Survey membership tools and kinematic analysis of NGC 6749
L. Rosignoli, M. Libralato, R. Pascale +15
The Hubble Missing Globular Cluster Survey has secured high quality astro photometric data in two bands for 34 clusters never observed with HST. When combined with Gaia positional…
Dynamical mirages: how bar-induced resonant trapping can mimic substructure clustering in dynamical parameter spaces
Michele De Leo, Davide Massari, Michele Bellazzini +3
The complex task of unraveling the assembly history of the Milky Way is in constant evolution with new substructures identified continuously. To properly validate and characterise…
A Walk on the Retrograde Side (WRS) project. II. Chemistry to disentangle in situ and accreted components in Thamnos
E. Ceccarelli, D. Massari, M. Palla +3
We present the results of the first systematic and dedicated high-resolution chemical analysis of the Thamnos substructure, a candidate relic of the process of hierarchical merger…
