A rounded view of Faraday

The Royal Institution & Michael Faraday: a Personal View

had completed by 1826. With the exception of Chemical Manipulation, all of Faraday's books had previously appeared in the periodical literature or else were transcriptions of public lectures. Like many another text, it arose out of a course, this one given at the Royal Institution as William Jensen describes in his "Michael Faraday and the Art and Science of Chemical Manipulation". Faraday had ...

A Bayesian view on Faraday rotation maps - Seeing the magnetic power spectra in galaxy clusters

We present a Bayesian maximum likelihood analysis of Faraday rotation measure (RM) maps of extended radio sources to determine magnetic field power spectra in clusters of galaxies. Using this approach, it is possible to determine the uncertainties in the measurements. We apply this approach to the RM map of Hydra A and derive the power spectrum of the cluster magnetic field. For Hydra A, we mea...

A View through Faraday ’ s Fog 2 : Parsec Scale Rotation Measures in 40 AGN

Results from a survey of the parsec scale Faraday rotation measure properties for 40 quasars, radio galaxies and BL Lac objects are presented. Core rotation measures for quasars vary from approximately 500 to several thousand rad m . Quasar jets have rotation measures which are typically 500 rad m or less. The cores and jets of the BL Lac objects have rotation measures similar to those found in...

Theory of the inverse Faraday effect in view of ultrafast magnetization experiments

We supplement the theory of the inverse Faraday effect, which was developed in the 1960s, to the conditions used today in ultrafast magnetization experiments. We show that assumptions used to derive the effective Hamiltonian and magnetization are not valid under these conditions. We extended the approach to be applicable to describe magnetization dynamics at femtosecond time scales. We show tha...
