Titre |
Modelling the cosmic history of galactic magnetic fields |
|
Résumé |
Do all spiral galaxies exhibit coherent magnetic fields? How are galactic magnetic fields amplified and
maintained? What is the distribution of field strengths? How did this change with time? In this talk, I address
these questions using a model which computes the magnetic properties of a statistical sample of evolving
galaxies. It employs a semi-analytic model of galaxy formation to produce realistic time-varying galactic
properties and numerically solves the dynamo equations from the early universe until the present. I will also
discuss what are the prospects for observationally constraining this and similar models using a range of
tracers. |
