Astronomy [Image] New Spitzer Discovery--"Flat Galaxies"

New observations from NASA’s Spitzer Space Telescope provide strong evidence that the slender, bulgeless galaxies can, like their heftier counterparts, harbor supermassive black holes at their cores. Previously, astronomers thought that a galaxy without a bulge could not have a supermassive black hole. In this illustration, jets shooting away from the black holes are depicted as thin streams.

The findings are reshaping theories of galaxy formation, suggesting that a galaxy’s core does not determine whether it will be harbor a supermassive black hole.
