Jonathan Marr's Research

High Resolution, Radio-Wavelength Observations of Radio Galaxies.

In "laymen's terms":  I use satellite-dish-like telescopes around the world which operate simultaneously to detect and map the invisible light emitted by sub-atomic particles that move at relativistic speeds around strong magnetic field lines in regions of space millions to billions of light-years away in which supermassive black holes, millions to billions times as massive as the Sun, reside.
