Flat rotation curves measured in ancient dusty starburst galaxies
but they rotate more than 2x faster than the Milky Way
This study utilizes extremely deep high-resolution data from the Atacama Large Millimeter / submillimeter Array (ALMA). Various molecules (e.g., water, carbon monoxide) are detected in a pair of dusty starburst galaxies called ‘HXMM01’, a mega-merger that occurred 10 billion years ago (see news story on Los Angeles Times). In both...
