The star formation histories of dwarf galaxies in Local Group cosmological simulations
Ruth Digby, Julio F. Navarro, Azadeh Fattahi +6
We use the APOSTLE and Auriga cosmological simulations to study the star formation histories (SFHs) of field and satellite dwarf galaxies. Despite sizeable galaxy-to-galaxy scatter…
The distinct stellar metallicity populations of simulated Local Group dwarfs
Anna Genina, Carlos S. Frenk, Alejandro Benitez-Llambay +4
A number of Local Group dwarf galaxies are known to have two spatially segregated stellar metallicity populations, a centrally concentrated metal-rich population and a more extende…
Subhalo destruction in the Apostle and Auriga simulations
Jack Richings, Carlos Frenk, Adrian Jenkins +7
N-body simulations make unambiguous predictions for the abundance of substructures within dark matter halos. However, the inclusion of baryons in the simulations changes the pictur…
No cores in dark matter-dominated dwarf galaxies with bursty star formation histories
Sownak Bose, Carlos S. Frenk, Adrian Jenkins +10
Measurements of the rotation curves of dwarf galaxies are often interpreted as requiring a constant density core at the centre, at odds with the "cuspy" inner profiles predicted by…
