The central supermassive black hole of a recently discovered galaxy called SAGE0536AGN is far larger than should be possible, according to current theories of galactic evolution. The galaxy was found by accident with NASA’s Spitzer space telescope and is thought to be at least 9 billion years old. Time will tell whether SAGE0536AGN really is an oddball, or simply the first in a new class of galaxies.
Many galaxies blast huge, wide-angled flows of material outward from their centres, pushing to their outer edges enough dust and gas each year that otherwise would have formed more than a thousand stars the size of our Sun. A team led by University of Maryland scientists has found the driving force behind these massive molecular outflows.
