Interpretation of Blazar Flux Variations as Music. Dr. James R. Webb Department of Physics Florida International University.
Blazars are believed to be distant galaxies in the process of formation. They emit electromagnetic radiation (light) over the entire electromagnetic spectrum from radio waves to gamma-rays. The emission varies with time in most frequency ranges and the causes for the variation are yet to be adequately explained. Astronomers have been monitoring these objects with optical telescopes for over 50 years now and we have collected a large database of brightnesses over these fifty years.
This paper presents some of these light curves, and adopts a computational method to translate the brightness fluctuations into musical tones. These tones are then converted to sound using a midi synthesizer on a PC.
The music you are hearing is the converted light curve from Active Galactic Nucleus 3C 120. This source is extremely energetic and variable and is located about 1 billion parsecs from Earth.
