The chosen few: the low-mass haloes that host faint galaxies
The chosen few: the low-mass haloes that host faint galaxies
Since reionization prevents star formation in most halos below 3 x 10^9 solar masses, dwarf galaxies only populate a fraction of existing dark matter halos. We use hydrodynamic cosmological simulations of the Local Group to study the discriminating factors for galaxy formation in the early Universe and connect them to …
