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 11 billion years ago are likely fed by similar cold streams.
- The study was published on the Astrophysical Journal: A Long Stream of Metal-Poor Cool Gas around a Massive Starburst Galaxy at z = 2.67. The discovery was built upon two previous studies led by our group:
- The multiwavelength data set associated with the study is available on my GitHub.
