Notable astronomers

Name Country Born Died Notable for
Marc Aaronson United States 1950 1987 His work concentrated on three fields: the determination of the Hubble constant (H0) using the Tully–Fisher relation, the study of carbon rich stars, and the velocity distribution of those stars in dwarf spheroidal galaxies.

Aaronson was one of the first astronomers to attempt to image dark matter using infrared imaging. He imaged infrared halos of unknown matter around galaxies that could be dark matter.
