NASA: Webb telescope reveals links between galaxies
UC physicist contributes to analysis of distant galaxies
NASA talked to a University of Cincinnati physicist about the significance of imaging extremely young galaxies using the James Webb Space Telescope.
UC College of Arts and Sciences postdoctoral researcher Keunho Kim was co-author on a research team that published a study in January in the Astrophysical Journal Letters. They examined compact galaxies undergoing high rates of star formation called “green peas.”

According to NASA, these galaxies depict colors — greens and reds — created by brightly glowing gas clouds.
“Peas may be small, but their star-formation activity is unusually intense for their size, so they produce bright ultraviolet light,” Kim told NASA. “Thanks to ultraviolet images of green peas from Hubble and ground-based research on early star-forming galaxies, it’s clear that they both share this property.”
The telescope was launched into orbit more than a year ago. It's offering the best look to date at distant phenomena in the universe.
Kim's research group presented its findings at the annual meeting of the American Astronomical Society in Seattle.
