The role of accreted and in situ populations in shaping the stellar halos of low-mass galaxies
Elisa A. Tau, Antonela Monachesi, Facundo A. Gomez +7
The stellar halos of dwarf galaxies are becoming an object of interest in the extragalactic community due to their detection in some recent observations. Additionally, new cosmolog…
Auriga Streams II: orbital properties of tidally disrupting satellites of Milky Way-mass galaxies
Nora Shipp, Alexander H. Riley, Christine M. Simpson +7
Galaxies like the Milky Way are surrounded by complex populations of satellites at all stages of tidal disruption. In this paper, we present a dynamical study of the disrupting sat…
Progenitor diversity in the accreted stellar halos of Milky Way-like galaxies
Sy-Yun Pu, Andrew P. Cooper, Robert J. J. Grand +2
Ongoing large stellar spectroscopic surveys of the Milky Way seek to reconstruct the major events in the assembly history of the Galaxy. Chemical and kinematic observations can be…
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…
Recovering chemical bimodalities in observed edge-on stellar disks: insights from AURIGA simulations
Francesca Pinna, Robert J. J. Grand, Marie Martig +1
We assessed the ability to recover chemical bimodalities in integral-field spectroscopy (IFS) observations of edge-on galaxies, using 24 Milky Way-mass galaxies from the AURIGA zoo…
The halo mass dependence of physical and observable properties in the circumgalactic medium
Andrew W. S. Cook, Freeke van de Voort, Rüdiger Pakmor +1
We study the dependence of the physical and observable properties of the CGM on its halo mass. We analyse 22 simulations from the Auriga suite of high resolution cosmological `zoom…
AuriDESI: Mock Catalogues for the DESI Milky Way Survey
Namitha Kizhuprakkat, Andrew P. Cooper, Alexander H. Riley +31
The Dark Energy Spectroscopic Instrument Milky Way Survey (DESI MWS) will explore the assembly history of the Milky Way by characterising remnants of ancient dwarf galaxy accretion…
Bar formation and evolution in the cosmological context: Inputs from the Auriga simulations
Francesca Fragkoudi, Robert Grand, Rüdiger Pakmor +3
Galactic bars drive the internal evolution of spiral galaxies, while their formation is tightly coupled to the properties of their host galaxy and dark matter halo. To explore what…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
Cosmological gas accretion history onto the stellar discs of Milky Way-like galaxies in the Auriga simulations -- (II) The inside-out growth of discs
Federico G. Iza, Sebastián E. Nuza, Cecilia Scannapieco +6
We investigate the growth of stellar discs in Milky Way-mass galaxies using the magnetohydrodynamical simulations of the Auriga Project in a full cosmological context. We focus on…
Cosmological evolution of metallicity correlation functions from the Auriga simulations
Zefeng Li, Robert J. J. Grand, Emily Wisnioski +7
We study the cosmological evolution of the two-point correlation functions of galactic gas-phase metal distributions using the 28 simulated galaxies from the Auriga Project. Using…
The role of AGN feedback on the evolution of dwarf galaxies from cosmological simulations: SMBHs suppress star formation in low-mass galaxies
Elena Arjona-Galvez, Arianna Di Cintio, Robert J. J. Grand
Aims. Recent observational studies suggest that feedback from active galactic nuclei (AGNs) may play an important role in the formation and evolution of low-mass dwarf galaxies, an…
Insight into the Galactic Bulge Chemodynamical Properties from Gaia DR3
Xiaojie Liao, Zhaoyu Li, Iulia Simion +4
We explore the chemodynamical properties of the Galaxy in the azimuthal velocity and metallicity [Fe/H] space using red giant stars from Gaia Data Release 3. The row-normaliz…
Overview and public data release of the augmented Auriga Project: cosmological simulations of dwarf and Milky Way-mass galaxies
Robert J. J. Grand, Francesca Fragkoudi, Facundo A. Gómez +4
We present an extended suite of the Auriga cosmological gravo-magnetohydrodynamical "zoom-in" simulations of 40 Milky Way-mass halos and 26 dwarf galaxy-mass halos run with the mov…
