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…
Drivers of disc tilting I: Correlations and possible drivers for Milky Way analogues
Samuel W. F. Earp, Victor P. Debattista, Andrea V. Macciò +3
The direction of the spin vectors of disk galaxies change over time. We present the tilting rate of a sample of galaxies in the NIHAO suite of cosmological hydrodynamical simulatio…
NIHAO XVIII: Origin of the MOND phenomenology of galactic rotation curves in a LCDM universe
Aaron A. Dutton, Andrea V. Macciò, Aura Obreja +1
The phenomenological basis for Modified Newtonian Dynamics (MOND) is the radial-acceleration-relation (RAR) between the observed acceleration, , and the accelerat…
