Post-starburst galaxy 0379 a unique find

Scientists studying post-starburst galaxies, or PSBs, found that they don't behave as expected. PSBs were previously believed to scatter their gas as they become dormant. New observations have revealed that these galaxies actually hang onto this gas and compact it near to their centers. PSB 0379.579.51789 is the one exception in the study. Here, radio data of the galaxy overlaid on optical images from the Hubble Space Telescope reveal that while the galaxy did hold onto its star-forming fuel, the collection of gas is located off-center.
