Deep Lens Survey
(investigating mass distribution of the universe)
The Deep Lens Survey (DLS) was a survey of distant
galaxies, with the aim of finding gravitational lensing,
to assist in determining the universe's mass distribution.
It was a photometric-based
survey using four bands of seven 4-square-degree
fields. It was carried out between 2001 and 2006 on
the Mayall 4m Telescope at Kitt Peak and the Víctor M. Blanco Telescope
at the Cerro Tololo Inter-American Observatory.
In addition to its cosmology aim, it discovered
planetoids, comets, and supernovae.
