New survey finds 'Peter Pan' radio galaxies that may never grow up

A team of astronomers has doubled the number of known young, compact radio galaxies — galaxies powered by newly energized black holes. The improved tally will help astronomers understand the relationship between the size of these radio sources and their age, as well as the nature of the galaxy itself. In particular, it will help astronomers understand why there are so many more young radio galaxies than old.
