Smoothed particle magnetohydrodynamics for simulations of galaxy and cosmic structure formation
Orestis A. Karapiperis, Matthieu Schaller, Nikyta Shchutskyi +2
We introduce a novel formulation of cosmological smoothed particle magnetohydrodynamics (SPMHD), designed to model magnetic field physics in a vast array of nonlinear astrophysical…
Kinematic dynamos and resolution limits for Smoothed Particle Magnetohydrodynamics
Nikyta Shchutskyi, Matthieu Schaller, Orestis A. Karapiperis +2
Understanding the origin and evolution of magnetic fields on cosmological scales opens up a window into the physics of the early Universe. Numerical simulations of such fields requ…
Traces of the evolution of cosmic void galaxies: An Integral Field Spectroscopy based analysis
AgustÃn M. RodrÃguez-Medrano, Dante J. Paz, Damián Mast +2
Galaxies in the most underdense regions of the Universe, known as cosmic voids, exhibit astrophysical properties that suggest a distinct evolutionary path compared to galaxies in d…
Gravitational to Coulomb force ratio and the origin of the Cosmic magnetic field
Nelson D. Padilla, Juan Racker, Ignacio J. Araya +1
The origin of the seeds of galactic magnetic fields is a subject that remains under debate. Here we will explore a simple source based on tiny charge asymmetries in slowly rotating…
The electric charge of black holes within galaxies
Nelson D. Padilla, Ignacio J. Araya, Federico Stasyszyn
We present improved estimates of the electric charge that black holes could hold when these are embedded in the ionised plasma within galaxies. We have implemented the spontaneous…
