The oldest Milky Way stars: New constraints on the age of the Universe and the Hubble constant
Elena Tomasetti, Cristina Chiappini, Samir Nepal +6
We exploit the most robust, old, and cosmology-independent age estimates of individual stars from Gaia DR3 to place a lower bound on the age of the Universe, . These constrain…
The impact of radial migration on disk galaxy star formation histories I. Biases in spatially resolved estimates
I. Minchev, K. Attard, B. Ratcliffe +9
Knowledge of the spatially resolved star formation history (SFH) of disk galaxies provides crucial insight into disk assembly, quenching, and chemical evolution. However, most reco…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +209
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
The Spheroidal Bulge of the Milky Way: Chemodynamically Distinct from the Inner-Thick Disc and Bar
Samir Nepal, Cristina Chiappini, Angeles Pérez-Villegas +7
Studying the composition and origin of the inner region of our Galaxy -- the "Galactic bulge" -- is crucial for understanding the formation and evolution of the Milky Way and other…
Tracing the Milky Way: Calibrating chemical ages with high-precision Kepler data
G. Casali, J. Montalbàn, A. Miglio +10
Chemical clocks offer a powerful tool for estimating stellar ages from spectroscopic surveys. We present a new detailed spectroscopic analysis of 68 Kepler red giant stars to provi…
Early Co-formation of the Milky Way's Thin and Thick Disks at Redshift z > 2
Lais Borbolato, Silvia Rossi, Hélio D. Perottoni +8
The Milky Way serves as a template for understanding the formation and evolution of late-type massive disk galaxies since we can obtain detailed chemical and kinematic information…
