Description
Primordial magnetic fields (PMF) may represent the "progenitors"
of the fields we observe in large scale structures and their
study could open a new observational window on the early universe. The
Cosmic Microwave Background, thanks to its different probes,
represents one of the best laboratory to investigate and constrain the
nature of PMF. I will present the Planck 2015 constraints on the
amplitude and spectral index of a stochastic background of PMF derived
using different methods.
