The Galactic inner spiral arms revealed by the Gaia ESO Survey chemical abundances. Metallicity and [Mg/Fe] ratios
C. Viscasillas Vázquez, L. Magrini, E. Spitoni +5
Recent observational advances, such as Gaia DR3 GSP-Spec, have highlighted the potential of chemical abundances in tracing and revealing the structure of spiral arms. Building on t…
Contribution of young massive star clusters to Galactic diffuse -ray emission
Stefano Menchiari, Giovanni Morlino, Elena Amato +3
Context: Young massive stellar clusters (YMSCs) have emerged as potential -ray sources, after the recent association of a dozen YMSCs with extended -ray emission. The large…
The Gaia-ESO Survey: 3D dynamics of young groups and clusters from GES and Gaia EDR3
Nicholas J. Wright, R. D. Jeffries, R. J. Jackson +9
We present the first large-scale 3D kinematic study of ~2000 spectroscopically-confirmed young stars (<20 Myr) in 18 star clusters and OB associations (hereafter groups) from the c…
The Gaia-ESO Survey DR5.1 and Gaia DR3 GSP-Spec: a comparative analysis
M. Van der Swaelmen, C. Viscasillas Vazquez, L. Magrini +10
(abridged) The third data release of Gaia, has provided stellar parameters, metallicity [M/H], [α/Fe], individual abundances, broadening parameter from its RVS spectra for about 5…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
