Aletheia: Emulating the non-linear matter power spectrum in the context of evolution mapping
Ariel G. Sanchez, Andrés N. Ruiz, Facundo Rodriguez +7
We present Aletheia, a new emulator of the non-linear matter power spectrum, , built upon the evolution mapping framework. This framework addresses the limitations of traditi…

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…
