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…
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…
Structure and kinematics of tidally limited satellite galaxies in LCDM
Raphaël Errani, Julio F. Navarro, Rodrigo Ibata +1
We use N-body simulations to model the tidal evolution of dark matter-dominated dwarf spheroidal galaxies embedded in cuspy Navarro-Frenk-White subhalos. Tides gradually peel off s…
Satellite mass functions and the faint end of the galaxy mass-halo mass relation in LCDM
Isabel M. E. Santos-Santos, Laura V. Sales, Azadeh Fattahi +1
The abundance of the faintest galaxies provides insight into the nature of dark matter and the process of dwarf galaxy formation. In the LCDM scenario, low mass halos are so numero…
The Pristine survey XIV: chemical analysis of two ultra-metal-poor stars
C. Lardo, L. Mashonkina, P. Jablonka +15
Elemental abundances of the most metal-poor stars reflect the conditions in the early Galaxy and the properties of the first stars. We present a spectroscopic follow-up of two ultr…
