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…

Differences in the Physical Properties of Satellite Galaxies within Relaxed and Disturbed Galaxy Groups and Clusters

F. Aldás, Facundo A. Gómez, C. Vega-Martínez +2

Galaxy groups and clusters are the most massive collapsed structures in the Universe. Those structures are formed by collapsing with other smaller structures. Groups and cluster me…

Galaxy evolution in compact groups II. Witnessing the influence of major structures in their evolution

Gissel P. Montaguth, Antonela Monachesi, Sergio Torres-Flores +15

Compact groups (CGs) of galaxies are extreme environments for morphological transformations and the cessation of star formation. Though initially considered isolated, it is now rec…

The distant Milky Way halo from the Southern hemisphere: Characterization of the LMC-induced dynamical-friction wake

Manuel Cavieres, Julio Chanamé, Camila Navarrete +6

The infall of the Large Magellanic Cloud (LMC) into the Milky Way's halo impacts the distribution of stars and dark matter in our Galaxy. Mapping the observational consequences of…

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…

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…
