The UV spectrum of the Seyfert 1 galaxy NGC 7469.

B. A. M. Westin

Abstract

Resultats de l'etude de 32 spectres IUE de la galaxie de Seyfert 1 NGC 7469. Au cours des observations, faites de juin 1978 a decembre 1982, le continuum a 1500 A a varie d'un facteur 2. Les raies d'emission fortes sont larges et asymetriques. Lyman α presente les variations d'intensite les plus intenses. On a identifie quelques raies d'absorption, intrinseques aussi bien que galactiques. NGC 7469 est un fort emetteur Fe II dans la region UV. L'etendue de la region emettrice de C IV est de l'ordre de 0,02 pc
