  MAORY is the Adaptive Optic (AO) module that will be installed at the E-ELT
at the first light of the telescope. It will provide two different types of AO
correction, a very high correction over a small FoV (diameter ~10 arcsec, SCAO
mode) and a moderate and homogeneous correction over a wide FoV (diameter ~60
arcsec, MCAO mode). Here we present a first collection of science cases for
MAORY feeding the E-ELT first light camera and spectrograph MICADO. Since the
general science cases for E-ELT have already been developed elsewhere, here we
focus on the design of specific observations, to explore the capabilities and
observing modes of the system.
