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 MartÃnez-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…
The JWST Galactic Center Survey -- A White Paper
Rainer Schoedel, Steve Longmore, Jonny Henshaw +111
The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…
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…
Cluster Ages to Reconstruct the Milky Way Assembly (CARMA). II. The age-metallicity relation of Gaia-Sausage-Enceladus globular clusters
Fernando Aguado-Agelet, Davide Massari, Matteo Monelli +8
We present the age determination of 13 globular clusters dynamically associated with the Gaia-Sausage-Enceladus (GSE) merger event, as part of the CARMA project effort to trace the…
Characterisation of local halo building blocks: Thamnos and Sequoia
Emma Dodd, Tomás Ruiz-Lara, Amina Helmi +5
A crucial aspect of galaxy evolution is the pace at which galaxies build up their mass. We investigate this hierarchical assembly by uncovering and timing accretion events experien…
