The dependence of cosmic ray driven galactic winds on halo mass
Svenja Jacob, Rüdiger Pakmor, Christine M. Simpson +2
Galactic winds regulate star formation in disk galaxies and help to enrich the circum-galactic medium. They are therefore crucial for galaxy formation, but their driving mechanism…
The multiplicity and anisotropy of galactic satellite accretion
Shi Shao, Marius Cautun, Carlos S. Frenk +4
We study the incidence of group and filamentary dwarf galaxy accretion into Milky Way (MW) mass haloes using two types of hydrodynamical simulations: EAGLE, which resolves a large…
Simulating Gamma-ray Emission in Star-forming Galaxies
C. Pfrommer, R. Pakmor, C. M. Simpson +1
Star forming galaxies emit GeV- and TeV-gamma rays that are thought to originate from hadronic interactions of cosmic-ray (CR) nuclei with the interstellar medium. To understand th…
Origin of chemically distinct discs in the Auriga cosmological simulations
Robert J. J. Grand, Sebastián Bustamante, Facundo A. Gómez +7
The stellar disk of the Milky Way shows complex spatial and abundance structure that is central to understanding the key physical mechanisms responsible for shaping our Galaxy. In…
Quenching and ram pressure stripping of simulated Milky Way satellite galaxies
Christine M. Simpson, Robert J. J. Grand, Facundo A. Gómez +5
We present predictions for the quenching of star formation in satellite galaxies of the Local Group from a suite of 30 cosmological zoom simulations of Milky Way-like host galaxies…
Lessons from the Auriga discs: The hunt for the Milky Way's ex-situ disc is not yet over
Facundo A. Gómez, Robert J. J. Grand, Antonela Monachesi +7
We characterize the contribution from accreted material to the galactic discs of the Auriga Project, a set of high resolution magnetohydrodynamic cosmological simulations of late-t…
