Relaxed blue ellipticals: accretion-driven stellar growth is a key evolutionary channel for low mass elliptical galaxies
(2023-04-30)
How elliptical galaxies form is a key question in observational cosmology. While the formation of massive ellipticals is strongly linked to mergers, the low mass (M⋆/M⊙ < 10^9.5 regime remains less well explored. In ...
Introducing the NewHorizon simulation : Galaxy properties with resolved internal dynamics across cosmic time
(2021-07-28)
Hydrodynamical cosmological simulations are increasing their level of realism by considering more physical processes and having greater resolution or larger statistics. However, usually either the statistical power of such ...
