Relativistic Jets from Active Galactic Nuclei by Blandford, Roger, Meier, David, Readhead, Anthony

“…The nuclei of most normal galaxies contain supermassive black holes, which can accrete gas through a disk and become active. These active galactic nuclei…”

Star Clusters Across Cosmic Time by Krumholz, Mark R, McKee, Christopher F, Bland-Hawthorn, Joss

“…Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational dynamics, stellar evolution, and cosmology. Here, we review…”
