Abstract / Description of output

We present results from very high signal-to-noise spectropolarimetric observations of the Seyfert 1 galaxy NGC 3783. Position angle (PA) changes across the Balmer lines show that the scatterer is resolving the broad emission-line region (BLR). A broad component seen in polarized light and located bluewards from the Hβ line very likely corresponds to He II λ4686. The lack of PA changes across this line suggests that the region responsible for this emission appears to the scatterer as unresolved as the continuum source, in agreement with the stratified BLR structure determined from reverberation mapping.
