Cosmic magnetism seeds tracers in LSS
Federico Stasyszyn
The origin of cosmic magnetic fields in the Universe remains as an open question in astrophysics. Cosmological magnetohydrodynamics (MHD) simulations have been proven as an effective tool to understand the cosmic structure formation process and the magnetic field evolution that we can infer from observations. In this work, we present results from a novel set of cosmological simulations aimed to study 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 of the enhancement of magnetic fields and confirm previous results obtained with structure formation models. Therefore, with these simulations, we are able to study the distribution of magnetic fields inside the different cosmic structures embedded within the cosmic web. In particular, we observe some differences between several seeding mechanisms or magnetogenesis models and build mock observations to distinguish between them within the currently available observational limits.
