Calán/Tololo Supernova Survey

(Calán/Tololo Supernova Search, Calán/Tololo Survey)
(late 1980s to early 1990s search to redshift 0.1)

The Calán/Tololo Supernova Survey (Calán/Tololo Supernova Search or just Calán/Tololo Survey) was a survey from 1989 to 1995 at the Cerro Tololo Inter-American Observatory aiming at supernovae out to redshift 0.1, to find Type Ia supernovae in order to make a more precise estimate of the Hubble constant. It was instrumental in establishing the acceleration that motivates the concept of dark energy.

An earlier (1980s) Calán Tololo Survey searched for Seyfert galaxies, emission line galaxies and quasars.
