Chemical clocks and their time zones: understanding the [s/Mg]--age relation with birth radii
Bridget Ratcliffe, Ivan Minchev, Gabriele Cescutti +5
The relative enrichment of s-process to -elements ([s/]) has been linked with age, providing a potentially useful avenue in exploring the Milky Way's chemical evolution. Howe…
Galactic ArchaeoLogIcaL ExcavatiOns (GALILEO) II. t-SNE Portrait of Local Fossil Relics and Structures
Mario Ortigoza-Urdaneta, Katherine Vieira, José G. Fernández-Trincado +7
Based on high-quality APOGEE DR17 and Gaia DR3 data for 1,742 red giants stars within 5 kpc of the Sun and not rotating with the Galactic disc ( 100 km s), we use the…
Beyond Gaia DR3: Tracing the [/M]-[M/H] bimodality from the inner to the outer Milky Way disc with Gaia-RVS and convolutional neural networks
G. Guiglion, S. Nepal, C. Chiappini +17
In June 2022, Gaia DR3 has provided the astronomy community with about one million spectra from the Radial Velocity Spectrometer (RVS) covering the CaII triplet region. However, on…
Unveiling the time evolution of chemical abundances across the Milky Way disk with APOGEE
Bridget Ratcliffe, Ivan Minchev, Friedrich Anders +12
Chemical abundances are an essential tool in untangling the Milky Way's enrichment history. However, the evolution of the interstellar medium abundance gradient with cosmic time is…
Spectroscopic age estimates for APOGEE red-giant stars: Precise spatial and kinematic trends with age in the Galactic disc
F. Anders, P. Gispert, B. Ratcliffe +12
Over the last few years, many studies have found an empirical relationship between the abundance of a star and its age. Here we estimate spectroscopic stellar ages for 178 825 red-…
The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151
The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
