Fluctuations in galactic bar parameters due to bar-spiral interaction

T. Hilmi, I. Minchev, T. Buck +10

We study the late-time evolution of the central regions of two Milky Way-like simulations of galaxies formed in a cosmological context, one hosting a fast bar and the other a slow…

The Strength of the Dynamical Spiral Perturbation in the Galactic Disk

Anna-Christina Eilers, David W. Hogg, Hans-Walter Rix +4

The mean Galactocentric radial velocities of luminous red giant stars within the mid-plane of the Milky Way reveal a spiral signature, which could plaus…

The effects of cosmic rays on the formation of Milky Way-mass galaxies in a cosmological context

Tobias Buck, Christoph Pfrommer, Rüdiger Pakmor +2

We investigate the impact of cosmic rays (CR) and different modes of CR transport on the properties of Milky Way-mass galaxies in cosmological magneto-hydrodynamical simulations in…

Local photoionization feedback effects on galaxies

Aura Obreja, Andrea V. Macciò, Benjamin Moster +5

We implement an optically thin approximation for the effects of the local radiation field from stars and hot gas on the gas heating and cooling in the N-body SPH code GASOLINE2. We…

On the origin of the chemical bimodality of disk stars: A tale of merger and migration

Tobias Buck

The Milky Way's stellar disk exhibits a bimodality in the [Fe/H] vs. [/Fe] plane, showing a distinct high- and low- sequence whose origin is still under debate. We examine…

NIHAO-UHD: The properties of MW-like stellar disks in high resolution cosmological simulations

Tobias Buck, Aura Obreja, Andrea V. Macciò +3

Simulating thin and extended galactic disks has long been a challenge in computational astrophysics. We introduce the NIHAO-UHD suite of cosmological hydrodynamical simulations of…
