CBS News: Physicists discover galaxy formed in early universe

UC physics professor Matthew Bayliss co-authored study on billions-year-old galaxy

CBS News in Chicago highlighted a physics study that identified a galaxy that formed in the early formation of the universe.

The international discovery was confirmed by observations from the Magellan telescopes in Chile and the Gemini North telescope in Hawaii.

University of Cincinnati physicist Matthew Bayliss, an assistant professor in UC's College of Arts and Sciences, was a study co-author. The lead author, Gourav Khullar, is a physics student at the University of Chicago.

Bayliss got his doctoral and master's degrees from the University of Chicago, where he worked as a research and teaching assistant before joining Harvard University as a research fellow.

Bayliss said they date the galaxy to when the universe was 1.2 billion years old – or about 10% of the universe's current age.

"This means that we will be able to use this galaxy to make much-higher-quality measurements of the properties of galaxies at such early times than had previously been possible," Bayliss said. "Finding a highly magnified galaxy like this gives us a great place to point our best observatories."

Researchers expect to get more data on this ancient galaxy from the Hubble Space Telescope and Chandra X-ray Observatory, Bayliss said.

The study was published in the Astrophysical Journal.
