Magnetic fields origins from Primordial Black Holes

Federico Stasyszyn (Universidad de Cordoba)

We will introduce the problem of magnetogésis which still is an open question. Within our current understanding of possible solutions, we explore the magnetic field creation during early epoch of the Universe where primordial black holes (PBH) are generated. After studying the statistics of PBH mass distributions we can derive the corresponding magnetic power spectrum from general formalisms of magnetic field generation. In particular we study the plausibility of two particular field generation mechanisms that could have given rise to the expected seed fields according to current observational constraints.
