The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
Shoko Jin, Scott C. Trager, Gavin B. Dalton +212
WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree…
Asymmetrical tidal tails of open star clusters: stars crossing their cluster's prah challenge Newtonian gravitation
Pavel Kroupa, Tereza Jerabkova, Ingo Thies +14
After their birth a significant fraction of all stars pass through the tidal threshold (prah) of their cluster of origin into the classical tidal tails. The asymmetry between the n…
Dipolar dark matter simulations on galaxy scales with the RAMSES code
Clément Stahl, Benoit Famaey, Guillaume Thomas +2
We numerically explore on galaxy scales the Dipolar dark matter (DM) model based on the concept of gravitational polarization. This DM model has been proposed as a natural way to r…
The PAndAS View of the Andromeda Satellite System. III. Dwarf galaxy detection limits
Amandine Doliva-Dolinsky, Nicolas F. Martin, Guillaume F. Thomas +6
We determine the detection limits of the search for dwarf galaxies in the Pan-Andromeda Archaeological Survey (PAndAS) using the algorithm developed by the PAndAS team. The recover…
The Pristine survey XVIII: C-19: Tidal debris of a dark matter-dominated globular cluster?
Raphaël Errani, Julio F. Navarro, Rodrigo Ibata +12
The recently discovered C-19 stellar stream is a collection of kinematically associated metal-poor stars in the halo of the Milky Way lacking an obvious progenitor. The stream span…
The Pristine survey -- XVII. The C-19 stream is dynamically hot and more extended than previously thought
Zhen Yuan, Nicolas F. Martin, Rodrigo A. Ibata +22
The C-19 stream is the most metal poor stellar system ever discovered, with a mean metallicity . Its low metallicity dispersion ( 0.18 at…
