Lecture 28: Groups & Clusters of Galaxies
from Astronomy 162 - Stars, Galaxies, & the Universe · host Richard Pogge
Galaxies are found in groups and clusters, and these are only the start of a hierarchy of cosmic structures up to the largest scales observed. This lecture introduces the properties of groups and clusters of galaxies, superclusters (clusters of clusters), and large scale structure with filaments of superclusters surrouning vast voids. We start with our Local Group, and then expand our view to encompass the depths of intergalactic space. Recorded 2006 February 14 in 1008 Evans Laboratory on the Columbus campus of The Ohio State University.
