A new astrophysical solution to the Too Big To Fail problem: Insights from the MORIA simulations

Verbeke, R; Papastergis, E; Ponomareva, Anastasia; Rathi, S; De Rijcke, Sven


Aims. We test whether or not realistic analysis techniques of advanced hydrodynamical simulations can alleviate the Too Big To Fail problem (TBTF) for late-type galaxies. TBTF states that isolated dwarf galaxy kinematics imply that dwarfs live in halos with lower mass than is expected in a A cold dark matter universe. Furthermore, we want to identify the physical mechanisms that are responsible for this observed tension between theory and observations. Methods. We use the MORIA suite of...[Show more]
