Primordial Magnetic Fields in Cosmology

Understand

Magnetic fields have been observed in galaxies, clusters of galaxies and probably in superclusters.

• While mechanisms exist to generate these in the late universe, it is possible that magnetic fields have existed since very early times.
• This thesis is concerned with methods to predict the form of such imprints.
• We review in detail a standard, linearised cosmology before introducing an electromagnetic field.
