ALMA

Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of researchers reports the first-ever detection of molecular gas -- the fuel for star formation -- in two galaxies that were previously rocked by gamma ray bursts (GRBs), the brightest explosions in the Universe. These new observations revealed that the molecular gas was concentrated toward the centers of the galaxies, while the GRBs occurred in unusual environments that were surprisingly bereft of gas yet rich in dust.
