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…

Modelling the Milky Way's exoplanet population based on cosmological galaxy simulations

Chloé Padois, Daniel del Ser, Friedrich Anders +7

In this paper we aim to simulate realistic exoplanet populations across different regions of the MW by combining state-of-the-art cosmological simulations of our Galaxy with exopla…

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 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…

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…
