The Pristine Dwarf-Galaxy survey -- V. The edges of the dwarf galaxy Hercules
Nicolas Longeard, Pascale Jablonka, Giuseppina Battaglia +6
We present a new spectroscopic study of the dwarf galaxy Hercules (d ~ 132 kpc) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together with the Two Deg…
The Pristine survey -- XV. A CFHT ESPaDOnS view on the Milky Way halo and disc populations
R. Lucchesi, C. Lardo, P. Jablonka +14
We present a one-dimensional, local thermodynamic equilibrium (1D-LTE) homogeneous analysis of 132 stars observed at high-resolution with ESPaDOnS. This represents the largest samp…
The Complexity of the Cetus Stream Unveiled from the Fusion of STREAMFINDER and StarGO
Zhen Yuan, Khyati Malhan, Federico Sestito +16
We combine the power of two stream-searching tools, STREAMFINDER and StarGO applied to the Gaia EDR3 data, to detect stellar debris belonging to the Cetus stream system that forms…
Gemini/GRACES Spectroscopy of Stars in Triangulum II
K. A. Venn, E. Starkenburg, L. Malo +2
The chemical abundance ratios and radial velocities for two stars in the recently discovered Triangulum II faint dwarf galaxy have been determined from high resolution, medium sign…
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…
Building Blocks of the Milky Way's Accreted Spheroid
Pim van Oirschot, Else Starkenburg, Amina Helmi +1
In the CDM model of structure formation, a stellar spheroid grows by the assembly of smaller galaxies, the so-called building blocks. Combining the Munich-Groningen semi-analyti…
