Using absorption lines in the spectra of two background quasars and deep ALMA observations in CO, our group discovered a cold gas stream in a massive dark matter halo. The stream is made of gas that is extremely poor in heavy elements. The detection signifies that massive starburst galaxies existed... [Read More]

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... [Read More]
