JAY GORY, MANAGING EDITOR, science
Astronomers have finally spotted evidence for their long-standing suspicion that the larger a galaxy's central supermassive black hole, the faster star formation in that neighborhood ends. "This is the first direct observational evidence where we can see the effect of the black hole on the star formation history of the galaxy," co-author Jean Brodie, an astronomer at the University of California, Santa Cruz, said in a press release. Stars, of course, don't come with birth certificates, but scientists can measure their ages based on what their light fingerprint looks like. Then, the team behind the new paper compared those ages with the size of the supermassive black hole at the center of the galaxies those stars live in, which other scientists had previously calculated. read more
