The Location of a Galaxy's Gas Plays a Role in Star Formation
Galaxies are stellar factories generating stars at different speeds—some working at a breakneck pace while others trickling along! We have known for a long time that the availability of raw materials makes a difference to stellar formation, but according to a new paper which surveyed 1,000 galaxies the location of the matter plays a role too. Those with a high stellar formation rate seem to have a high volume of gas reserves in the heart of their densest star clusters with the highest concentration of stars.
