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…
First evidence of a collision between two unrelated open clusters in the Milky Way
Andrés E. Piatti, Khyati Malhan
We report the first evidence of an on-going collision between two star clusters in our Galaxy, namely IC 4665 and Collinder 350. These are open clusters located at a distance of ~3…
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…
Uncovering fossils of the distant Milky Way with UNIONS: NGC 5466 and its stellar stream
Jaclyn Jensen, Guillaume Thomas, Alan W. McConnachie +9
We examine the spatial clustering of blue horizontal branch (BHB) stars from the -band of the Canada-France Imaging Survey (CFIS, a component of the Ultraviolet Near-In…
The Pristine Dwarf-Galaxy survey -- IV. Probing the outskirts of the dwarf galaxy Boötes I
Nicolas Longeard, Pascale Jablonka, Anke Arentsen +12
We present a new spectroscopic study of the dwarf galaxy Bootes I (Boo I) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together with the Two Degree Fi…
The Pristine survey XIII: Uncovering the very metal-poor tail of the thin disc
Emma Fernández-Alvar, Georges Kordopatis, Vanessa Hill +9
We evaluate the rotational velocity of stars observed by the Pristine survey towards the Galactic anticentre, spanning a wide range of metallicities from the extremely metal-poor r…
