Astronomer leverages supercomputers to study black holes, galaxies

Astronomer Stelios Kazantzidis leveraged the powerful resources of the Ohio Supercomputer Center to simulate and study several cosmological phenomena. His recent investigations revealed that supermassive black holes don't necessarily grow in relation to the mass of their host-galaxies when the galaxies merge, and small "disky dwarf" galaxies -- loaded with dark-matter -- often lose mass to their larger neighbor-galaxies and evolve from disk-shaped to spheroid.
