Cosmological beam plasma instabilities

Shalaby, Mohamad (University of Waterloo, 2017-08-24)

Blazars are the main source of extragalactic very high energy gamma-rays. These gamma rays annihilate on the extragalactic background light, producing electron-positron pair beams with TeV energies. The pair beams are very ...
The Nature and Impact of Active Galactic Nuclei

Tiede, Paul (University of Waterloo, 2021-08-12)

The gravitational interaction around the event horizon of black holes presents theoretical challenges. With the advent of the Event Horizon Telescope (EHT), we are now entering an era in physics where we can probe the ...
The Relationship Between Active Galactic Nuclei and Metal-enriched Outflows in Galaxy Clusters

Kirkpatrick, Charles (University of Waterloo, 2012-01-25)

Clusters of galaxies are host to powerful Active Galactic Nuclei (AGN) that greatly affect the thermal history of clusters. By keeping X-ray emitting gas from cooling, massive, run away star formation does not occur in the ...
