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…
How homogeneous was the chemical enrichment of the Milky Way 13 gigayears ago?
Riano E. Giribaldi, Laura Magrini, Martina Rossi +3
We reanalyze the chemical composition of the metal-poorest tail of the Galactic halo using highly accurate atmospheric parameters Giribaldi et al. (2021, 2023) and cutting-edge 3D…
The metal-poorest tail of the Galactic halo: hypothesis on its origin from precise spectral analysis
Riano E. Giribaldi, Laura Magrini, Martina Rossi +3
The origin of the Galactic halo is one of the fundamental topics linking the study of galaxy formation and evolution to cosmology. We aim at deriving precise and accurate stellar p…
The earliest phases of CNO enrichment in galaxies
Martina Rossi, Donatella Romano, Alessio Mucciarelli +3
Context. The recent detection of nitrogen-enhanced, metal-poor galaxies at high redshift by the James Webb Space Telescope has sparked renewed interest in exploring the chemical ev…
