Calán/Tololo Survey
| Target | supernovae |
|---|---|
The Calán/Tololo Supernova Survey was a
CTIO with a CCD
camera. This was one of the first studies done in astronomy where the telescope time was scheduled to observe objects not yet discovered.
The survey discovered 50 supernovae between 1990 and 1993, of which 32 were
accelerated expansion of the universe
in 1998.
The calibration of Type Ia supernovae as standard candles led to the precise measurements of the
Hubble flow measurements both by the High-Z Supernova Search Team and the Supernova Cosmology Project. Their pioneering work was cited in the award of the 2011 Nobel Prize in Physics[11]
