Supermassive black holes in 'red geyser' galaxies cause galactic warming
Science Daily ^ | 5/25/2016 | University of Kentucky

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.

Akira's gravity pulls Tetsuo's gas into its central supermassive black hole, fueling winds that have the power to heat Akira's gas. Because of the action of the black hole winds, Tetsuo's donated gas is rendered inert, preventing a new cycle of star formation in Akira.

Obviously they didn’t listen to Al Gore.

Somehow I do not believe this theory. It sounds too much like global warming and probably a propaganda piece. Think like taking water out of one of a swimming pool and putting it in the other except this time it is heat.

Just like Hollywood.

Maybe there is global warming, maybe there isn’t. What I do know is that Man doesn’t have a damn thing to do with it.

I think Al Gore is causing galactic warming with his tin mines in Tenn.

Black holes in red geysers. The racism abounds.

Yeah why do they have call them black holes and red geysers. That’s racess.

Stop Anthropomorphic Galactic Warming!

[Little humor there.]

Supermassive black holes in ‘red geyser’ galaxies only cause galactic warming because whites are racist...

They need to start selling black hole wind credits, ASAP. Or the whole universe will die.

Relax our galaxy has several billion years to go so you’ll have ample time to get your affairs in order.
