Local Group Dwarf Galaxies: Nature And Nurture [PDF]
, 2011 We investigate the formation and evolution of dwarf galaxies in a high resolution, hydrodynamical cosmological simulation of a Milky Way sized halo and its environment.

NIHAO XV: the environmental impact of the host galaxy on galactic satellite and field dwarf galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We study the impact of the host on dwarf galaxy properties using four new Milky Way-like, ultra high-resolution simulations, ($N_{\rm part} >10^7$) from the NIHAO project. We split our sample in satellite ($R 2.5 R_{\rm 200}$) galaxies.

The Astrophysical Journal, 2023 Dwarf galaxies located in extremely underdense cosmic voids are excellent test beds for disentangling the effects of large-scale environments on galaxy formation and evolution. We present the first results of the Dwarfs in Void Environments Survey, which

On the dynamics of the Sagittarius dwarf galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 We use numerical simulations to test the feasibility of the suggestion by Ibata et al. (1994) that the excess population of stars which they discovered in the Sagittarius region may be the disrupted remains of a dwarf spheroidal galaxy. We find that a Fornax-like model for the pre-disruption system can indeed reproduce the data.

The PAndAS View of the Andromeda Satellite System. IV. Global Properties
The Astrophysical Journal, 2023 We build a statistical framework to infer the global properties of the satellite system of the Andromeda galaxy (M31) from the properties of individual dwarf galaxies located in the Pan-Andromeda Archaelogical Survey (PAndAS) and the previously ...

Pushing back the limits: detailed properties of dwarf galaxies in a ΛCDM universe [PDF]
Astronomy & Astrophysics, 2018 We present the results of a set of high-resolution chemo-dynamical simulations of dwarf galaxies in a ΛCDM cosmology. Out of an original (3.4 Mpc/h)3 cosmological box, a sample of 27 systems are re-simulated from z = 70 to z = 0 using a zoom-in technique.

Target Selection and Sample Characterization for the DESI LOW-Z Secondary Target Program
The Astrophysical Journal, 2023 We introduce the DESI LOW- Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method.
