Research Interests

Cluster Plasma Physics

The intracluster medium (ICM) is comprised of hot plasma (ionized gas). Our knowledge of fluid dynamics and plasma physics can be applied to the study of the ICM.

AGN feedback Cooling & Heating

Active galactic nuclei (AGN) are the engines of the cooling and heating cycles taking place at the centers of galaxy clusters.

Cluster outskirts & Cosmology

Galaxy clusters represent the final stage of the hierarchical formation, and they are potent laboratories for testing models of structure formation.

Early-type galaxies & X-ray Binaries

Present day early-type galaxies tend to contain substantial atmospheres of hot gas. The thermal and chemical properties of this gas reservoir preserve much of the history of the galaxy.
