An international team of scientists, including the University of Kentucky's Renbin Yan, have uncovered a new class of galaxies, called "red geysers," with supermassive black hole winds so hot and energetic that stars can't form.
Over the last few billion years, a mysterious kind of "galactic warming" has caused many galaxies to change from a lively place where new stars formed every now and then to a quiet place devoid of fresh young stars. But the mechanism that produces this dramatic transformation and keeps galaxies quiet has been one of the biggest unsolved mysteries in galaxy evolution.
"These galaxies have the necessary ingredients for forming new stars but they are not doing it -- why?" said Yan, an assistant professor of physics and astronomy at UK
**********
Red geysers are old galaxies hosting low-energy supermassive black holes which drive intense interstellar winds. These winds suppress star formation by heating up the ambient gas found in galaxies and preventing it from cooling and condensing into stars.

Non-sense! Human caused globull warming! That is all!
On the other hand, interesting, and goes to show how little we know of our universe.
“galactic warming”
With a term like galactic warming you can quadruple the size of your grant request and walk around knowing that the odds of approval fall into the “lead pipe cinch” category. Outstanding!
well, if there’s GALACTIC warming going on, then we can safely stop listening to Al Gore’s krapola scam about mere, unimportant, tiny, teenyweeny “global warming”
Cosmic CO2. How can we blame the rich, capitalist planets?
Many of the stars in those galaxies identify as brown dwarfs, further complicating a number of interstellar issues.
“galactic warming”
Oh crap...we’re screwed.”
No lo sweato Senor, Los Greenies have a sure 5 light year long plan to get rid od the “REDS”....
“Supermassive black holes in ‘red geyser’ galaxies cause galactic warming”
Women and children suffer the most.
Or, maybe it happened long, long ago and far, far away and we’ve just become aware of it. Worth a grant? Probably when you look at some things which get grants. At least this actually happened and might teach us something.
Damned “fossil” fuels!
See what they’ve done now!
Guess our scientists will now consensus that the center of these galaxies contain coal plants and automobile engines.
We have complicated the universe?
Would I be correct in assuming that women and minorities will be hardest hit?
Criminy! Galatic warming is WAY worse than global warming, right?
I'm obviously not physicist material - the "low-energy supermassive black holes" bit flummoxed me.
Red geezer = Bernie
You are probably better material than you give yourself credit. All they had to revise and correct their statement would have been to say “comparatively low energy”.
Thanks JimSEA, extra to APoD.
