My Academic Tree: I’m a descendant of the discoverer of X-rays!

My research field is Extragalactic X-ray Astronomy. In particular, I study the formation of large scale structure in the Universe: galaxy clusters, superclusters, and filaments. Structure formation involves energetic collisions of massive objects that produce a ~100 million Kelvin plasma as well as relativistic protons and electrons. These in turn produce a characteristic X-ray signature that I use to study the physics of structure formation. Recent work has been in the area of galaxy evolution in groups and clusters, cosmic ray acceleration in galaxy cluster mergers, and the discovery of a new class of objects called Dark X-ray Galaxies.

I am editing a special issue on “High Energy Emission from Clusters, Groups, and Filaments: Current Observations and Future Prospects” in the journal, Universe. Submissions and inquiries are welcome. Follow the link for more information.
