Investigating the Structure of the Windy Torus in Quasars
S. C. Gallagher, J. E. Everett, M. M. Abado +1
Thermal mid-infrared emission of quasars requires an obscuring structure that can be modeled as a magneto-hydrodynamic wind in which radiation pressure on dust shapes the outflow.…
Active Galactic Nuclei, Neutrinos, and Interacting Cosmic Rays in NGC 253 & NGC 1068
Tova M. Yoast-Hull, J. S. Gallagher, Ellen G. Zweibel +1
The galaxies M82, NGC 253, NGC 1068, and NGC 4945 have been detected in gamma-rays by Fermi. Previously, we developed and tested a model for cosmic ray interactions in the starburs…
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…
Winds, Clumps, and Interacting Cosmic Rays in M82
Tova M. Yoast-Hull, John E. Everett, J. S. Gallagher +1
We construct a family of models for the evolution of energetic particles in the starburst galaxy M82 and compare them to observations to test the calorimeter assumption that all co…
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…
The Interaction of Cosmic Rays with Diffuse Clouds
John E. Everett, Ellen G. Zweibel
We study the change in cosmic-ray pressure, the change in cosmic-ray density, and the level of cosmic-ray induced heating via Alfven-wave damping when cosmic rays move from a hot i…
