Stars with fast Galactic rotation observed in Gaia TGAS: a signature driven by the Perseus arm?
Jason A. S. Hunt, Daisuke Kawata, Giacomo Monari +3
We report on the detection of a small overdensity of stars in velocity space with systematically higher Galactocentric rotation velocity than the Sun by about 20 km s in the…
Evidence of ongoing radial migration in NGC 6754: Azimuthal variations of the gas properties
L. Sánchez-Menguiano, S. F. Sánchez, D. Kawata +9
Understanding the nature of spiral structure in disk galaxies is one of the main, and still unsolved questions in galactic astronomy. However, theoretical works are proposing new t…
Properties of HI discs in the Auriga cosmological simulations
Federico Marinacci, Robert Grand, Rüdiger Pakmor +4
We analyse the properties of the HI gas distribution in the Auriga project, a set of magnetohydrodynamic cosmological simulations performed with the moving-mesh code AREPO and a ph…
The Auriga Project: the properties and formation mechanisms of disc galaxies across cosmic time
Robert J. J. Grand, Facundo A. Gómez, Federico Marinacci +6
We introduce a suite of thirty cosmological magneto-hydrodynamical zoom simulations of the formation of galaxies in isolated Milky Way mass dark haloes. These were carried out with…
The effects of bar-spiral coupling on stellar kinematics in the Galaxy
Giacomo Monari, Benoit Famaey, Arnaud Siebert +3
We investigate models of the Milky Way disc taking into account simultaneously the bar and a two-armed quasi-static spiral pattern. Away from major resonance overlaps, the mean ste…
Warps and waves in the stellar discs of the Auriga cosmological simulations
Facundo A. Gómez, Simon D. M. White, Robert J. J. Grand +3
Recent studies have revealed an oscillating asymmetry in the vertical structure of the Milky Way's disc. Here we analyze 16 high-resolution, fully cosmological simulations of the e…
Spiral-induced velocity and metallicity patterns in a cosmological zoom simulation of a Milky Way-sized galaxy
Robert J. J. Grand, Volker Springel, Daisuke Kawata +6
We use a high resolution cosmological zoom simulation of a Milky Way-sized halo to study the observable features in velocity and metallicity space associated with the dynamical inf…
Impacts of a Flaring Star-forming Disc and Stellar Radial Mixing on the Vertical Metallicity Gradient
D. Kawata, R. J. J. Grand, B. K. Gibson +3
Using idealised N-body simulations of a Milky Way-sized disc galaxy, we qualitatively study how the metallicity distributions of the thin disc star particles are modified by the fo…
