Scientists Discover Millions Of Hidden Black Holes Eating Hot DOGs

Scientists have detected millions of previously hidden supermassive black holes surrounding us, some of them busily eating newly discovered "extremely bright and extremely rare" galaxies called hot DOGs (Dust-Obscured Galaxies). Astronomy is fun!

Using NASA's Wide-Field Infrared Survey Explorer, astronomers have been able to locate a staggering amount of these supermassive black holes: about 2.5 million. These quasars were hidden before because of dust clouds, but NASA is quickly uncovering them thanks to WISE's Nuclear Spectroscopic Telescope Array (NuSTAR). According to Jet Propulsion Laboratory's Daniel Stern:

We've got the black holes cornered. WISE is finding them across the full sky, while NuSTAR is giving us an entirely new look at their high-energy X-ray light and learning what makes them tick.

Quasars start their life as dead colossal stars that collapse at the end of their lives, attracting mass around them until they grow into supermassive hungry beasts, feeding on whatever gas and dust surrounds them, becoming more and more massive in a never-ending cycle. As the quasar eats, it gets extremely hot, emitting light that can be captured by WISE's instruments.

These mighty black holes are also found in the hearts of these rare galaxies, so bright and hot that they emit 100 trillion times as much light as the Sun.

We couldn't see the blackholes or these galaxies with normal telescopes because they are obscured by dust. Only WISE, with its infrared instruments, has been able to detect these hidden fiery furnaces.

Both discoveries have been quite surprising. According to Jingwen Wu, a JPL scientist who lead one of the research papers, "we may be seeing a new, rare phase in the evolution of galaxies." So rare, in fact, that Peter Eisenhardt — project scientist for WISE at JPL — says that "these dusty, cataclysmically forming galaxies are so rare WISE had to scan the entire sky to find them. What is more amazing, according to Eisenhardt, is that they are seeing that some of the galaxies "may have formed their black holes before the bulk of their stars."

"The eggs may have come before the chickens."

So much talk about eggs, chickens and hog dogs just made me hungry. [NASA]

    Except Gravity is a dimension in which we can travel so a bunch of black holes mean they went that away...

      Not sure where you heard or read that gravity is a dimension that can be traveled, but I'd like to know which direction the so called dark flow is... well, flowing in..? :)

    My question is does this go some ways to explaining all the "missing" mater in the universe? Are the dark matter buffs collectively facepalming?

      +1 to this. Hey here's a fun thing to consider, what if the outward acceleration of the observable universe is the pull of all these black holes, and the "edge of the observable universe" is stuff getting sucked into them, and the CMB is actually a shitload of Hawking radiation ... and due to time dilation, we are unable to perceive that this "net" of black holes is closing in on the observable universe ... FUN :D

    There's a theory about White Holes which is the other end of the black hole that which emits all that has sucked through it's wormhole. They believe that white holes are in fact BIG BANGS that start entire universes. So in theory.... through every black hole is a whole new universe.

    In other words.... the big bang of our universe was created from a white hole.

      I think 'Stephen Hawking' would disagree, but I'm more inclined to believe that they (black Holes) empty out into the same bubble, or dimension or whatever and maybe explode from there into an actual Universe when they reach a critical mass or something. The product of just one black hole just wouldn't be enough to be a fully fledged Universe unless they're mini Universes... :)

      I don't believe black holes go anywhere or emit into anything as such. However, a universe could exist inside that black hole. Think of a tv screen, within a tv screen. The second tv screen can't exist without the first tv screen. But is still a closed system, within a closed system.

      Go read about super liquids and you will see that the physics inside behave in similar manner to the known universe. Perhaps, there is a "Secondary" event horizon within the black hole where the originating universes physics (all that compression) cease to exist and there is a reset of sorts where normal physics kick in again. Like the eye of a hurricane.

      Similar to what racemethorphan said, what if we exist inside one of these black holes as part of another bigger universe. What we are seeing as the expansion of our universe, is in fact just the edge of our black whole expanding as it sucks in more and more matter from the outside universe. Maybe most of this sucked in matter presents as dark matter that we can't see.

      Haha, but I'm waffling on now. Interesting topic.
