Abstract: Our team from LESIA (Observatoire de Paris) has just benefited from the installation of two new instruments: NAOS/CONICA, the VLT adaptive optics system and its infrared camera, and GriF, the 3-D spectrograph coupled with the CFHT adaptive optics system PUEO. In the quest for the detection of the internal morphological structures invoked by the unified model in active galactic nuclei (molecular disk, dust/gas torus, cusp, micro-bars and micro-spirals), high spatial resolution is mandatory since their predicted size, from 1 to 100 pc, even for the nearest AGNs (15 Mpc for example for NGC 1068) corresponds to subarcsecond dimensions. Thanks to adaptive optics, a spatial scale as small as 2.5 pc (resp. 6 pc) is now accessible on NGC 1068 in imaging and spectroscopy with NAOS/CONICA (resp. GriF). Recently, the long-slit spectroscopic mode of GriF was used for the first time to observe the central part of NGC 1068 and the first observations of AGNs made with NAOS/CONICA were performed on the Sombrero galaxy (M104) and NGC 3081 during commissionning phase. Preliminary results from these observations will be presented in a poster during this conference.
