High Signal-to-Noise Ratio Mid-Infrared Quasar Spectral Templates

Allison R. Hill, S. C. Gallagher, R. P. Deo +2

Mid-infrared (MIR) quasar spectra exhibit a suite of emission features including high ionization coronal lines from the narrow line region (NLR) illuminated by the ionizing continu…

Characterizing Quasars in the Mid-infrared: High Signal-to-Noise Spectral Templates

Allison R. Hill, S. C. Gallagher, R. P. Deo +2

Mid-infrared (MIR) quasar spectra exhibit a suite of emission features including high ionization coronal lines from the narrow line region illuminated by the ionizing continuum, br…

Why a Windy Torus?

S. C. Gallagher, M. M. Abado, J. E. Everett +2

Mass ejection in the form of winds or jets appears to be as fundamental to quasar activity as accretion, and can be directly observed in many objects with broadened and blue-shifte…

Sweeping Away the Mysteries of Dusty Continuous Winds in AGN

S. K. Keating, J. E. Everett, S. C. Gallagher +1

An integral part of the Unified Model for Active Galactic Nuclei (AGNs) is an axisymmetric obscuring medium, which is commonly depicted as a torus of gas and dust surrounding the c…

Looking for the Wind in the Dust

S. C. Gallagher, J. E. Everett, S. K. Keating +2

The blue-shifted broad emission lines and/or broad absorption lines seen in many luminous quasars are striking evidence for a broad line region in which radiation driving plays an…

CIV Emission and the Ultraviolet through X-ray Spectral Energy Distribution of Radio-Quiet Quasars

Nicholas E. Kruczek, Gordon T. Richards, S. C. Gallagher +6

In the restframe UV, two of the parameters that best characterize the range of emission-line properties in quasar broad emission-line regions are the equivalent width and the blues…
