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…
Merger-Induced Metallicity Dilution in Cosmological Galaxy Formation Simulations
Sebastian Bustamante, Martin Sparre, Volker Springel +1
Observational studies have revealed that galaxy pairs tend to have lower gas-phase metallicity than isolated galaxies. This metallicity deficiency can be caused by inflows of low-m…
The stellar orbit distribution in present-day galaxies inferred from the CALIFA survey
Ling Zhu, Glenn van de Ven, Remco van den Bosch +16
Galaxy formation entails the hierarchical assembly of mass, along with the condensation of baryons and the ensuing, self-regulating star formation. The stars form a collisionless s…
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…
Metallicity Gradient of the Thick Disc Progenitor at High Redshift
D. Kawata, C. Allende Prieto, C. B. Brook +6
We have developed a novel Markov Chain Mote Carlo (MCMC) chemical "painting" technique to explore possible radial and vertical metallicity gradients for the thick disc progenitor.…
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…
The slight spin of the old stellar halo
Alis J. Deason, Vasily Belokurov, Sergey E. Koposov +4
We combine Gaia data release 1 astrometry with Sloan Digital Sky Survey (SDSS) images taken some ~10-15 years earlier, to measure proper motions of stars in the halo of our Galaxy.…
Magnetic field formation in the Milky Way-like disk galaxies of the Auriga project
Ruediger Pakmor, Facundo A. Gomez, Robert J. J. Grand +8
The magnetic fields observed in the Milky~Way and nearby galaxies appear to be in equipartition with the turbulent, thermal, and cosmic ray energy densities, and hence are expected…
