Nelson Caldwell, Matthew G. Walker, Mario Mateo +6
We present results from MMT/Hectochelle spectroscopy of red giant candidate stars along the line of sight to the recently-discovered Galactic satellite Crater 2. Modelling the join…
Wide binaries in ultra-faint galaxies: a window onto dark matter on the smallest scales
Jorge Peñarrubia, Aaron D. Ludlow, Julio Chanamé +1
We carry out controlled -body simulations that follow the dynamical evolution of binary stars in the dark matter (DM) haloes of ultra-faint dwarf spheroidals (dSphs). We find th…
Solo Dwarfs I: Survey introduction and first results for the Sagittarius Dwarf Irregular Galaxy
C. R. Higgs, A. W. McConnachie, M. Irwin +6
We introduce the Solitary Local Dwarfs Survey (Solo), a wide field photometric study targeting every isolated dwarf galaxy within 3 Mpc of the Milky Way. Solo is based on (u)gi mul…
