Implications of a contracted dark matter halo for the Milky Way's inferred virial mass
Diego Dado, Shaun T. Brown, Azadeh Fattahi +2
We investigate how reliably the global properties of Milky Way-mass dark matter haloes can be recovered from dynamical data over a limited radial range, particularly $\lesssim 30~\…
LYRA ultra-faints: The emergence of faint dwarf galaxies in the presence of an early Lyman-Werner background
Shaun T. Brown, Azadeh Fattahi, Thales A. Gutcke +6
We present a suite of zoom-in cosmological hydrodynamical simulations of dwarf galaxies using the LYRA galaxy formation model with an extremely high mass resolution of $4\, \mathrm…
Co-evolution of baryons and dark matter halos of LYRA dwarf galaxies
Joaquin Sureda, Shaun T. Brown, Azadeh Fattahi +4
We use the extremely high-resolution () LYRA cosmological galaxy formation simulations of six dwarf galaxies with at…
Auriga Streams I: disrupting satellites surrounding Milky Way-mass haloes at multiple resolutions
Alexander H. Riley, Nora Shipp, Christine M. Simpson +8
In a hierarchically formed Universe, galaxies accrete smaller systems that tidally disrupt as they evolve in the host's potential. We present a complete catalogue of disrupting gal…
ARTEMIS emulator: exploring the effect of cosmology and galaxy formation physics on Milky Way-mass haloes and their satellites
Shaun T. Brown, Azadeh Fattahi, Ian G. McCarthy +3
We present the new ARTEMIS Emulator suite of high resolution (baryon mass of M) zoom-in simulations of Milky Way mass systems. Here, three ha…
