Introduction CFHTLS-Deep
Par Genevieve Soucail - 22/08/2006
The CFHTLS Deep survey
Summary
Covering 4 square degrees in four MegaCam fields through the whole filter set (u*g’r’i’z’) with integration times ranging from 33 to 132 hours depending on the filter (u*:33 g’:33, r’:66, i’:132, z’:66), this survey will be sequenced over 5 years at an average rate of 5.25 nights a dark run for 5 runs in a row each year on each field. Aimed mainly at the detection and monitoring of as many as 2000 type I SNe and at the study of the galaxy distribution on images reaching r’ 28, this survey will allow a better understanding of the early universe as well as a determination of the dark energy parameter with an unprecedented accuracy. The galaxies and quasars will allow to build statistical samples bringing strong constraints on galaxy evolution and global star formation history. Thanks to the sequencing, transient phenomena and moving objects will be detected and followed up, providing a unique monitoring over five years of fields at various galactic and ecliptic latitudes.
A total of 202 nights is allocated to the CFHTLS Supernovae/Deep Survey.
