UCI astronomers analyze second-most distant quasar

Using three observatories on Maunakea in Hawaiʻi, astronomers at the University of Arizona have discovered the second-most distant quasar ever found. As part of an international effort to confirm and study the newly discovered object, a team at UCI and UC Santa Barbara used the Keck II 10-meter telescope to perform a spectroscopic analysis. The […]

Astronomers from UCI and Texas A&M peer into distant black hole’s ‘sphere of influence’

Astronomers at UCI and Texas A&M University have obtained the most detailed view yet of an inner cold gas disk around a distant supermassive black hole. Studying the giant elliptical galaxy NGC 3258 with the Atacama Large Millimeter/submillimeter Array – a powerful radio telescope array in the high desert of northern Chile – the scientists […]
