Simulating Galactic Magnetohydrodynamics: The Role of Magnetic Fields in Galaxy Evolution
The origin of cosmic magnetic fields in the Universe remains an open question in astrophysics. Cosmological magnetohydrodynamics (MHD) simulations have been proven to be an effective tool for understandingthe cosmic structure formation process and the magnetic field evolution, which we can infer from observations. We present results from a novel set of cosmological simulations aimed at studying different magnetogenesis scenarios. Our set of runs have been obtained using the MHD version of the smoothed particle hydrodynamics code SWIFT and explores different mass resolutions, seeding mechanisms and astrophysical models. We focus on different astrophysical processes responsible for enhancing magnetic fields and confirm previous results obtained with structure formation models. Therefore, with these simulations, we can study the distribution of magnetic fields inside the different cosmic structures embedded within the cosmic web. In particular, we observe differences in the alignment between the spin of galaxies and their magnetic fields between two different magnetogenesis models.
