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.

UC students plan documentary in Eastern Europe during the war 

December 2, 2022

As global media descends on Eastern Europe to cover Russia’s war in Ukraine, two University of Cincinnati students are planning to cover the region from a different angle. Hunter Shallcross and Tanmay Srivastava, both digital media collaborative majors in the College of Arts and Sciences, have planned a trip to multiple European countries to film their own documentary, titled “The Edge of Chaos.” The trip is scheduled for May of 2023.  The pair became friends through their passion for film, and soon started partnering on projects. Last February, Shallcross and Srivastava became interested in the way culture and art are changing in countries on the edge of Europe due to the war, and decided to develop the idea into a documentary. “Everybody is flocking to Eastern Europe to document what is going on. We want it to show the artistic side,” says Shallcross. “The shots, the camera angles, and the narrative we want to tell about relationships and personal issues that go beyond war.”  They began pitching their documentary idea to various professors and making any connections they could to bring their idea to life. Last May, they even attended the Cannes Film Festival, to get some first-hand film experience, while networking with people there.
