Black holes are firing a triple-threat of speedy particles at us

Black holes have the weirdest kids. Three types of the highest energy particles in the cosmos could all be born in the chaos near a supermassive black hole  

Mystery Deepens "About Link Between Supermassive Black Holes and Cosmic Islands We Call Galaxies"

"The Earth, like many planets and stars, has a magnetic field that sprouts out of the North Pole, circles the planet and goes back into the South Pole," says Chris Packham, associate professor of physics and astronomy at The University...        

"Radio Monsters" --Some Supermassive Black Holes Blast Matter and Radio Waves Back Into Space Near Speed of Light

Black holes absorb light and all other forms of radiation, making them impossible to detect directly. But the effects of black holes, in particular accretion disks where matter is shredded and superheated as it spirals down into the black hole,...        

How We Know Black Holes Exist [Science Video]

This video is about the astronomical amount of astronomical evidence for black holes, ranging from x-ray binaries with accretion disks, supermassive infrared-radiating galactic nuclei black holes, orbital characteristics of high mass binaries, and direct gravitational wave detection of inspiraling merging black hole binaries with LIGO.

Black hole spin cranks-up radio volume

(National Institutes of Natural Sciences) Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly...Show More Summary

Black hole spin cranks-up radio volume

Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves and other radiation across the universe.

360-degree video puts you at the center of the galaxy

A newly released 360-degree video lets you explore the galactic center of the Milky Way from the perspective of the supermassive black hole at the heart of our galaxy, Sagittarius A (Sgr A). The immersive simulation visualizes how aShow More Summary

Researchers catch supermassive black hole burping—twice

A team led by CU Boulder researchers has caught a supermassive black hole in a distant galaxy snacking on gas and then "burping"—not once, but twice.

Mysterious series of fast radio bursts may have been twisted by extreme environment

Astronomers watching a fast-radio burst flashing from more than 3 billion light-years away say that its source lies in an extreme environment with a powerful magnetic field — perhaps a supermassive black hole, or the remains of a supernova. The findings about the phenomenon known as FRB 121102,...

Supermassive Black Holes 'Spawn' Dwarf Galaxies --"Outnumber Larger Galaxies Like Our Milky Way 50 to One"

"Dwarf galaxies outnumber larger galaxies like the Milky Way 50 to one," says lead researcher Dr Samantha Penny, of the University of Portsmouth Institute of Cosmology and Gravitation. "So if we want to tell the full story of galaxies, we...        

How massive is Supermassive? Astronomers measure more black holes, farther away

Today, astronomers from the Sloan Digital Sky Survey (SDSS) announced new measurements of the masses of a large sample of supermassive black holes far beyond the local Universe.

Black hole research could aid understanding of how small galaxies evolve

(University of Portsmouth) Scientists have solved a cosmic mystery by finding evidence that supermassive black holes prevent stars forming in some smaller galaxies.

"Beyond Comprehension!" --Collision of Two Supermassive Black Holes Will Dwarf the LIGO Gravitational-Wave Discovery (Today's Most Popular)

"They absolutely dwarf the black hole mergers detected by LIGO," the Laser Interferometer Gravitational-Wave Observatory, which first detected gravitational waves from colliding black holes in February 2016, "and will be detected within 10 years," says Chiara Mingarelli, a Marie Curie...        

Supermassive Black Holes Stop Galaxies From Making New Stars

The galaxies of the universe grow up kind of like we do. When they’re young, they’re very active, producing new stars out of clouds of dust at a rapid rate. As they age, the churning slows down and eventually stops. No more new stars. The galaxies settle into some relative peace and quiet.

Supermassive Black Holes May Eventually Sterilize Galaxies

A team led by UC Santa Cruz's Ignacio Martín-Navarro says supermassive black holes are playing a critical role in extinguishing galaxies. The post Supermassive Black Holes May Eventually Sterilize Galaxies appeared first on ExtremeT...

the geometry of nuclear black hole accretion disks

Supermassive black holes with millions or even billions of solar-masses of material are found at the nuclei of most galaxies, including our Milky Way. A torus of dust and gas orbits around the black hole (at least according to most theories)...Show More Summary
