Nuevos estudios espectroscópicos de galaxias IRAS

Observations of four IRAS objects are presented. From their optical spectral characteristics they are classified according to their degree of nuclear activity: two of them as Seyfert 1.9 types and one as an HII region-like galaxy; the remaining one turns out to be a star. Electron temperature and de...
