Can we really pick and choose? Benchmarking various selections of Gaia Enceladus/Sausage stars in observations with simulations
Andreia Carrillo, Alis J. Deason, Azadeh Fattahi +2
Large spectroscopic surveys plus Gaia astrometry have shown us that the inner stellar halo of the Galaxy is dominated by the debris of Gaia Enceladus/Sausage (GES). With the richne…
Unravelling the mass spectrum of destroyed dwarf galaxies with the metallicity distribution function
Alis J. Deason, Sergey E. Koposov, Azadeh Fattahi +1
Accreted stellar populations are comprised of the remnants of destroyed galaxies, and often dominate the `stellar haloes' of galaxies such as the Milky Way (MW). This ensemble of e…
Energy wrinkles and phase-space folds of the last major merger
Vasily Belokurov, Eugene Vasiliev, Alis J. Deason +5
Relying on the dramatic increase in the number of stars with full 6D phase-space information provided by the Gaia Data Release 3, we discover unambiguous signatures of phase-mixing…
Galactic tides and the Crater II dwarf spheroidal: a challenge to LCDM?
Alexandra Borukhovetskaya, Julio F. Navarro, Raphael Errani +1
The unusually low velocity dispersion and large size of Crater II pose a challenge to our understanding of dwarf galaxies in the Lambda Cold Dark Matter (LCDM) cosmogony. The low v…
Using the Multi-Object Adaptive Optics demonstrator RAVEN to observe metal-poor stars in and towards the Galactic Centre
Masen Lamb, Kim Venn, David Andersen +16
The chemical abundances for five metal-poor stars in and towards the Galactic bulge have been determined from H-band infrared spectroscopy taken with the RAVEN multi-object adaptiv…
The oldest and most metal poor stars in the APOSTLE Local Group simulations
Else Starkenburg, Kyle A. Oman, Julio F. Navarro +5
We examine the spatial distribution of the oldest and most metal poor stellar populations of Milky Way-sized galaxies using the APOSTLE cosmological hydrodynamical simulations of t…
