Quasar hosts: Growing up with monstrous middles

摘要

The Hubble Space Telescope has shown us the homes of nearby quasars in revealing detail,and has dealt us surprising answers to some of our long-standing questions about quasar hostgalaxy morphology. However, like all cutting-edge instruments, HST has taught us that the veryquestions we were asking were not necessarily the most interesting ones. Exploring the latterwill require a combination of ground- and space-based work over the remaining lifetime of HST.and beyond. Such studies promise to give us insight into the formation and evolution of galaxieslike our own over the whole history of the Universe.
