Primary fields of research
Dark matter particle properties, and characteristics of dark matter structures.
Current research
I am presently trying to understand and measure properties of equilibrated dark matter structures such as density and velocity anisotropy profiles. I also search an understanding of the origin of hot gas properties, such as temperature and density profiles.
