Schawinski was part of a team of researchers that used two renowned orbiting observatories, the Hubble Space Telescope and the Chandra X-Ray Observatory, to identify a population of black holes in galaxies at redshift 6, which corresponds to a time about 950 million years after the big bang.

Theorists now concur that massive stars must spew fantastic jets of energy into space when their cores collapse into black holes, but they disagree about what those jets look like.
