Hints of a disrupted binary dwarf galaxy in the Sagittarius stream
Elliot Y. Davies, Stephanie Monty, Vasily Belokurov +1
In this work, we look for evidence of a non-unity mass ratio binary dwarf galaxy merger in the Sagittarius stream. Simulations of such a merger show that, upon merging with a host,…
The Pristine Inner Galaxy Survey (PIGS) VIII: Characterising the orbital properties of the ancient, very metal-poor inner Milky Way
Anke Ardern-Arentsen, Giacomo Monari, Anna B. A. Queiroz +19
The oldest stars in the Milky Way (born in the first few billion years) are expected to have a high density in the inner few kpc, spatially overlapping with the Galactic bulge. We…
Disrupted dwarf binary merger as the possible origin of NGC 2419 and Sagittarius stream substructure
Elliot Y. Davies, Vasily Belokurov, Stephanie Monty +1
Using -body simulations, we demonstrate that satellite dwarf galaxy pairs which undergo significant mixing ( Gyr) can have their respective most bound particles separate…
Pyxis: A ground-based demonstrator for formation-flying optical interferometry
Jonah T. Hansen, Samuel Wade, Michael J. Ireland +6
In the past few years, there has been a resurgence in studies towards space-based optical/infrared interferometry, particularly with the vision to use the technique to discover and…
The odd bunch: chrono-chemo-dynamics of sixteen unusual stars from Kepler
Arthur Alencastro Puls, Luca Casagrande, Stephanie Monty +4
In this study we combine asteroseismic, spectroscopic and kinematic information to perform a detailed analysis of a sample of 16 stars from the Kepler field. Our selection focuses…
The GeMS/GSAOI Galactic Globular Cluster Survey (G4CS) II: Characterization of 47 Tuc with Bayesian Statistics
Mirko Simunovic, Thomas H. Puzia, Bryan Miller +5
We present a photometric analysis of globular cluster 47 Tuc (NGC\,104), using near-IR imaging data from the GeMS/GSAOI Galactic Globular Cluster Survey (G4CS) which is in operatio…
Peeking beneath the precision floor -- II. Probing the chemo-dynamical histories of the potential globular cluster siblings, NGC 288 and NGC 362
Stephanie Monty, David Yong, Davide Massari +8
The assembly history of the Milky Way (MW) is a rapidly evolving subject, with numerous small accretion events and at least one major merger proposed in the MW's history. Accreted…
