Mientras observaban una galaxia recién inactiva utilizando el Atacama Large Millimeter/submillimeter Array (ALMA) y el Telescopio Espacial Hubble (HST), un equipo científico descubrió que este había dejado de formar estrellas no porque hubiera agotado todo su gas, sino porque la mayor parte de su combustible para la formación de estrellas había sido expulsado del sistema cuando se fusionó con otra galaxia. Este resultado constituye una primicia para los astrónomos y astrónomas de ALMA. Además, si se demuestra que este resultado es común, podría cambiar la forma en que la comunidad científica entiende las fusiones y muertes de galaxias.

While observing a newly-dormant galaxy using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope (HST), scientists discovered that it had stopped forming stars not because it had used up all of its gas but because most of its star-forming fuel had been thrown out of the system as it merged with another galaxy. The result is a first for ALMA scientists. What’s more, if proven common, the results could change the way scientists think about galaxy mergers and deaths.

Post-starburst galaxies were previously thought to scatter all of their gas and dust—the fuel required for creating new stars—in violent bursts of energy, and with extraordinary speed.

Instead, after their supposed end, these dormant galaxies hold onto and compress large amounts of highly-concentrated, turbulent gas. But contrary to expectation, they’re not using it to form stars.
