MAIN POINTS

A Lively Supercluster
"A billion light-years from Earth lies one of the universe’s most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies known as Abell 2597. At the core of the central galaxy, a supermassive black hole is powering the cosmic equivalent of a monumental fountain, drawing in vast stores of cold molecular gas and spraying them back out again in an ongoing cycle."
(For nine billion years. see CHANDRA main points, below.)

Engine of Life & Death
“According to the researchers, this entire system operates via a self-regulating feedback loop. The infalling material provides power for the fountain as it “drains” toward the central black hole, like water entering the pump of a fountain. This infalling gas then causes the black hole to ignite with activity, launching high-velocity jets of super-heated material that shoot out of the galaxy. As it travels, this material pushes out clumps and streamers of gas into the galaxy’s expansive halo, where it eventually rains back in on the black hole, triggering the entire process anew.”

A Big Engine…
“In total, about three billion solar masses of molecular gas is part of this fountain, forming a filamentary nebula that spans the innermost 100,000 light-years of the galaxy.”

A Composite Image
“The ALMA and MUSE data were combined with a new, ultra-deep observation of the cluster by NASA's Chandra X-ray Observatory…,” with each revealing an aspect of the structure, ALMA the cold gas, MUSE the warm gas, and Chandra, the, “hot phase.”

“This multiwavelength approach offers an uncommonly complete picture of this system. ”

Photo Caption
"The yellow is ALMA data of the cold gas. The red is data from the Very Large Telescope showing the hot hydrogen gas in the same region. The extend purple is the extended hot, ionized gas as imaged by the Chandra X-ray Observatory."

NASA, CHANDRA, March 4, 2015.

MAIN POINTS

“The Chandra data indicate that the regulation of this precipitation has been going on for the last 7 billion years or more.”

"This study revealed that an unusual form of cosmic precipitation enables a feedback loop of cooling and heating, stifling star formation in the middle of these galaxy clusters."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
