A two-stage settling of the Milky Way disk revealed by precise ChronoGal ages

David Mirabal, Carme Gallart, Tomás Ruiz-Lara +9

The spatial distribution of Galactic disk stars of different ages and metallicities encodes its dynamical evolution history and formation pathways. The lack of precise ages for lar…

Evidence of a massive accretion event 1.8 billion years before the Gaia-Sausage-Enceladus merger

Davide Massari, Chiara Zerbinati, Cristiano Fanelli +15

The merger history of the Galaxy has been traced back firmly to redshift 2 (10 Billion years ago). While evidence for the existence of at least one more significant merger before t…

Is Crater II disrupting?

A. Katherina Vivas, Alistair Walker, Clara Martínez-Vázquez +5

Crater~II (CraII) is a very intriguing, low-surface brightness and extended galaxy in the vicinity of our Milky Way. Motivated by its huge area and the number of RR Lyrae stars (RR…

Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal): IV. On the inner Milky Way stellar age distribution

Tomás Ruiz-Lara, David Mirabal, Carme Gallart +15

The Milky Way's inner region is dominated by a stellar bar and a boxy-peanut shaped bulge. However, which stellar populations inhabit the inner Galaxy or how star formation proceed…

Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal) II. Unveiling the formation and evolution of the kinematically selected Thick and Thin Discs

Emma Fernández-Alvar, Tomás Ruiz-Lara, Carme Gallart +16

Understanding the formation and evolution of the Milky Way's thin and thick discs is crucial to galaxy formation studies. We derive age and metallicity distributions of the kinemat…

Chronology of our Galaxy from Gaia CMD-fitting (ChronoGal): the early formation of the Milky Way disk and the impact of Gaia-Sausage-Enceladus

C. Gallart, E. Fernández-Alvar, S. Cassisi +7

The derivation of precise stellar ages is considered the current major challenge to reconstruct the chronology of the Milky Way. Color-magnitude diagram (CMD)-fitting offers a robu…
