JWST Sees the Most Distant Active Supermassive Black Hole - by spacewriter
Finding black holes in the early universe in early galaxies opens up our understanding of that time in cosmic history. It is shortly after the Big Bang. For example, this newly found CEERS galaxy and its active supermassive black hole surprised astronomers. CEERS 1019 existed at a time when the first galaxies were forming. So, they should be small and relatively featureless, right? And, if they have black holes at that early epoch, those should be relatively low-mass .
So, how do CEERS 1019 and its black hole measure up? The galaxy itself appears as three bright clumps without a disk. So, it’s really still assembling itself and. “We’re not used to seeing so much structure in images at these distances,” said CEERS team member Jeyhan Kartaltepe, an associate professor of astronomy at the Rochester Institute of Technology in New York.
Interestingly, the black hole turns out to be more like Sagittarius A*, the one in the center of the Milky Way. And, that’s exciting even while it’s still puzzling. “Looking at this distant object with this telescope is a lot like looking at data from black holes that exist in galaxies near our own,” said Rebecca Larson, a recent Ph.D. graduate at UT Austin, who led the study of these objects.
