Abstract

Les observations spectroscopiques de la galaxie de Seyfert NGC 5728 sont presentees. Le spectre de la region centrale est decompose en profils gaussiens. Les cartes d'intensite, de vitesse et de dispersion sont determinees et analysees. La presence d'une region a raies larges est etablie. NGC 5728 est proposee comme galaxie de Seyfert de (faible) type 1.
