3. COSMOS Goals
Study the assembly of visible and dark matter up to scales of 1014h-1 M as a function of redshift.
Study the evolution of galaxies and AGNs as a function of the environment and redshift.

5. Area As large as possible ! Wide area is time consuming
Need to have a variety of environment at all redshift.
Wide area is time consuming
2 square degrees
50 Mpc at z = 0.5
88 Mpc at z = 1
137 Mpc at z = 2
170 Mpc at z = 3
