Astrophysics of Gaseous Nebulae and Active Galactic Nuclei
TL;DR: In this paper, a comparison of theory with observations internal dynamics of gaseous nebulae interstellar dust H II regions in the galactic context is presented. But the results are limited to the case of active galactic nuclei.
Journal ArticleDOI
Spectral classification of emission - line galaxies
TL;DR: In this paper, a revised method of classification of narrow-line active galaxies and H II region-like galaxies is proposed, which involves the line ratios which take full advantage of the physical distinction between the two types of objects and minimize the effects of reddening correction and errors in the flux calibration.
Journal ArticleDOI
The spectra of narrow-line Seyfert 1 galaxies.
TL;DR: In this article, measurements of a group of active galactic nuclei with all the properties of Seyfert 1 or 1.5 galaxies, but with unusually narrow H I lines are presented.
Journal Article
Active galactic nuclei.
TL;DR: On passe en revue les observations relatives a la structure des noyaux galactiques actifs and aux conditions physiques qui y regnent, principalement les donnees optiques.
