Explaining Gravitational Behaviors...

New Study Suggests 'Pac-Man-like' Mergers could explain Massive, Spinning Black Holes,
Rochester Institute of Technology, November 8, 2019.

MAIN POINTS

Black Holes within Massive Black Hole's Accretion Disk?
"The largest merger detected (by LIGO) so far seems to have defied previous models because it has a higher spin and mass than the range thought possible."

Impossible
or,
Black Holes Spinning Around Black Holes?
"...such large mergers could happen just outside supermassive black holes at the center of active galactic nuclei. Gas, stars, dust and black holes become caught in a region surrounding supermassive black holes known as the accretion disk. The researchers suggest that as black holes circle around in the accretion disk, they eventually collide and merge to form a bigger black hole, which continues to devour smaller black holes, becoming increasingly large in what O’Shaughnessy calls “Pac-Man-like” behavior."

"It offers a natural way to explain high mass, high spin binary black hole mergers and to produce binaries in parts of parameter space that the other models cannot populate. There is no way to get certain types of black holes out of these other formation channels."

More Data Coming
"As the LIGO and Virgo collaboration continue to hunt for gravitational waves, O'Shaughnessy and his fellow researchers hope to find signatures of large, spinning black holes that could help confirm their models."

Biggest Picture
"If their assumptions are correct, it could help us better understand how the cosmic web of galaxies assembles."

"It offers unique insight into how the centers of galaxies grow, which is of course essential to understanding how galaxies as a whole grow, which explains most of the structure in the universe."

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!
