The emission spectrum of the strong Fe II emitter BAL Seyfert 1 galaxy IRAS 07598+6508

M. -P. Veron, M. Joly, P. Veron +3

The narrow-line Seyfert 1 galaxy IRAS 07598+6508 is known to be a stong Fe II emitter. The analysis of several high S/N ratio spectra shows that its spectrum is dominated by a rela…

Blueshifted [O III] Emission: Indications of a Dynamic NLR

Todd Boroson

The [O III] 5007 line is commonly used as an indicator of the systemic redshift of AGNs. Also, recent studies have used the width of this emission line as a proxy for the stellar v…

Does the Narrow [O III] 5007 Line Reflect the Stellar Velocity Dispersion in AGN?

Todd A. Boroson

It has been proposed that the width of the narrow [O III] 5007 emission line can be used as a surrogate for the stellar velocity dispersion in active galaxies. This proposition is…

Black Hole Mass and Eddington Ratio as Drivers for the Observable Properties of Radio-Loud and Radio-Quiet QSOs

Todd A. Boroson

Recent studies of black holes in the nuclei of both active and normal galaxies have yielded relationships that permit a physical interpretation of the principal components of the s…

A Faint Luminous Halo that May Trace the Dark Matter around Spiral Galaxy NGC~5907

Penny D. Sackett, Heather L. Morrison, Paul Harding +1

The presence of unseen halos of ``dark matter'' has long been inferred from the high rotation speeds of gas and stars in the outer parts of spiral galaxies. The volume densit…
