Scientists find elusive gas from post-starburst galaxies hiding in plain sight
Scientists once thought that post-starburst galaxies scattered all of their gas and dust — the fuel required for creating new stars — in violent bursts of energy, and with extraordinary speed. Now, a team led by University of Washington postdoctoral researcher Adam Smercina reports that these galaxies don’t scatter all of their star-forming fuel after all. Instead, data from the Chile-based Atacama Large Millimeter/submillimeter Array, or ALMA, reveals a more complex process at work.
