Scientific paper

The GOODS NICMOS Survey is a large Hubble Space Telescope programme to obtain deep H-band and J-band imaging over the GOODS-North and South fields. The total exposure time is 180 orbits within the F160W filter (H-band) in fields surrounding massive galaxies with log M>11 at 2>z<3. This survey covers 1/3 of a GOODS field, and reaches a depth of H = 26.5 AB. In this talk I will review the latest results from this survey, including examination of the mass assembly rates, merger rates, sizes, and black hole growth for massive galaxies at z<3. Science results I will present include the first measurement of the merger and pair fraction, and quantified size evolution history for massive galaxies at z<3, as well as how black holes in massive galaxies grown with time, as well as future activities measuring the star formation rates evolution in these galaxies.
