Science Requirements Impacting AO Architecture Claire Max Architecture Meeting July

2 Science Cases Considered Most strongly determinant of NGAO system design –Galactic Center: general relativity measurements –High-redshift field galaxies –Planets around low-mass stars –Black hole mass measurements in nearby AGNs –Distant galaxies lensed by galaxies Other science cases –Asteroid size and shape –Asteroid companions –Debris disks and protostellar objects –Moons of the giant planets –QSO host galaxies Special case: NGS observations of Uranus and Neptune

3 Summary of AO Architecture Requirements from Science Cases (all)

4 AO Requirements Roll-Up for First Five Science Cases

5 Instrument requirements, first six science cases

6 Other comments If we want to do NGS observations of Neptune and Uranus, WFS needs to be able to accept large objects –Neptune of order 1 arc sec –Uranus of order 4 arc sec
