The discovery of the faintest known Milky Way satellite using UNIONS
Simon E. T. Smith, William Cerny, Christian R. Hayes +14
We present the discovery of Ursa Major III/UNIONS 1, the least luminous known satellite of the Milky Way, which is estimated to have an absolute V-band magnitude of $+2.2^{+0.4}_{-…
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…
The effect of a disc on the population of cuspy and cored dark matter substructures in Milky Way-like galaxies
Raphaël Errani, Jorge Peñarrubia, Chervin F. P. Laporte +1
We use high-resolution -body simulations to study the effect of a galactic disc on the dynamical evolution of dark matter substructures with orbits and structural parameters ext…
