Cosmological gas accretion history onto the stellar discs of Milky Way-like galaxies in the Auriga simulations -- (I) Temporal dependency
Federico G. Iza, Cecilia Scannapieco, Sebastián E. Nuza +5
We use the 30 simulations of the Auriga Project to estimate the temporal dependency of the inflow, outflow and net accretion rates onto the discs of Milky Way-like galaxies. The ne…
Possibilities and Limitations of Kinematically Identifying Stars from Accreted Ultra-Faint Dwarf Galaxies
Kaley Brauer, Hillary Diane Andales, Alexander P. Ji +4
The Milky Way has accreted many ultra-faint dwarf galaxies (UFDs), and stars from these galaxies can be found throughout our Galaxy today. Studying these stars provides insight int…
Is the core-cusp problem a matter of perspective: Jeans Anisotropic Modeling against numerical simulations
Wenting Wang, Ling Zhu, Zhaozhou Li +14
Mock member stars for 28 dwarf galaxies are constructed from the cosmological Auriga simulation, which reflect the dynamical status of realistic stellar tracers. The axis-symmetric…
The stellar halo in Local Group Hestia simulations III. Chemical abundance relations for accreted and in-situ stars
Sergey Khoperskov, Ivan Minchev, Noam Libeskind +10
Since the chemical abundances of stars are the fossil records of the physical conditions in galaxies, they provide the key information for recovering the assembly history of galaxi…
The stellar halo in Local Group Hestia simulations II. The accreted component
Sergey Khoperskov, Ivan Minchev, Noam Libeskind +12
In the Milky Way, recent progress in the exploration of its assembly history is driven by the tremendous amount of high-quality data delivered by Gaia, which has revealed a number…
The stellar halo in Local Group Hestia simulations I. The in-situ component and the effect of mergers
Sergey Khoperskov, Ivan Minchev, Noam Libeskind +12
Theory suggests that mergers play an important role in shaping galactic discs and stellar haloes, which was observationally confirmed in the MW thanks to Gaia data. In this work, a…
