    The stellar halo in Local Group Hestia simulations. I. The in situ component and the effect of mergers
    Theory suggests that mergers play an important role in shaping galactic discs and stellar haloes, which was observationally confirmed in the Milky Way (MW)...

    The stellar halo in Local Group Hestia simulations. III. Chemical abundance relations for accreted and in situ stars
    Stellar chemical abundances and kinematics provide key information for recovering the assembly history of galaxies. In this work we explore the chemo-chrono...
