The UV galaxy luminosity function at z=3-5 from the CFHT Legacy Survey Deep fields

Understand

We measure and study the evolution of the UV galaxy Luminosity Function (LF) at z=3-5 from the largest high-redshift survey to date, the Deep part of the CFHT Legacy Survey.

• We also give accurate estimates of the SFR density at these redshifts.
• We consider ~100,000 Lyman-break galaxies at z~3.1, 3.8 & 4.8 selected from very deep ugriz images of this data set and estimate their rest-frame 1600A luminosity function.
• Due to the large survey volume, cosmic variance plays a negligible role.
