Mass of the dynamically hot inner stellar halo predicts the ancient accreted stellar mass
<jats:p>Galactic dynamical structures are fossil records of the assembly histories of galaxies. By analyzing the cosmological hydrodynamical simulation TNG50, we find that a dynamical structure that we call the "hot inner stellar halo", defined by stars on dynamically hot orbits with...
