Supergiant GCIRS 22 in the Milky Way Nuclear Star Cluster: Revised alpha abundances
B. Thorsbro, S. Khalidy, R. M. Rich +7
Context: The chemical abundances of alpha-elements in Galactic Centre (GC) supergiants provide key insights into the chemical enrichment and star formation history of the Milky Way…
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…
Chemical Abundances in the Nuclear Star Cluster of the Milky Way: alpha-Element Trends and Their Similarities with the Inner Bulge
N. Ryde, G. Nandakumar, M. Schultheis +15
A chemical characterization of the Galactic Center is essential for understanding its formation and structural evolution. Trends of alpha-elements, such as Mg, Si, and Ca, serve as…
The GALAH Survey: Data Release 4
S. Buder, J. Kos, E. X. Wang +36
The stars of the Milky Way carry the chemical history of our Galaxy in their atmospheres as they journey through its vast expanse. Like barcodes, we can extract the chemical finger…
Spectroscopic characterisation of gravitationally lensed stars at high redshifts
Emma Lundqvist, Erik Zackrisson, Calum Hawcroft +2
Deep imaging of galaxy cluster fields have in recent years revealed tens of candidates for gravitationally lensed stars at redshifts 1-6, and future searches are expecte…
Abundances of iron-peak elements in accreted and in situ born Galactic halo stars
P. E. Nissen, A. M. Amarsi, Á. Skúladóttir +1
Previous work on the abundances of C, O, Na, Mg, Si, Ca, Ti, Cr, Mn, Fe, Ni, Cu, and Zn in low-alpha (accreted) and high-alpha (in situ born) halo stars is extended to include the…
