Bio
My work is mainly on the topic of clusters of galaxies. Galaxy clusters are the largest objects in the universe which are held together by gravity. They consist of hundreds to thousands of galaxies (each of which contains many billions of stars), moving through a very hot diffuse gas or plasma. This gas is known as the intracluster medium (ICM) and has a temperature of 10s of millions of degrees C. The hot gas emits X-rays which we can observe from observatories orbiting the Earth such as Chandra and XMM-Newton.
Some of the interesting scientific questions I am trying to address involve the interaction of the central supermassive black holes which lie in cluster cores with the surrounding intracluster medium. The intracluster medium in the cores of galaxy clusters should be cooling soon as it is emitting a lot of energy from X-rays. The problems I am working on include, How much gas is cooling in clusters?, Do the black holes stop the cooling of the ICM?, If they do, how do they stop cooling? To answer these questions I look at the nearest, brightest galaxy clusters in detail. Here is some information on recent research.
