Galaxy clusters and
superclusters are the largest coherent structures in the Universe and,
as such, provide a unique test bed for evaluation of many of the core
principles of modern cosmology. In particular, multi-wavelength
investigations of clusters allow us to probe the dynamical state of the
large-scale structure and give as a cosmic “barometer” with which to
measure the “weather” in the Universe. Dr Melanie Johnston-Hollitt is
involved in a variety of projects centred on observations of clusters
and superclusters, these include but are not limited to:
 Observations
of Radio Relics and Halos
Magnetic
Fields in Galaxy Clusters
Spectroscopic
Observations of Superclusters

potential research projects please have a look at the opportunities page or write to Melanie.
